Top 20 Aluminum Extrusion Machining Service Factories by Production Need

Last updated: October 2026

The best aluminum extrusion machining service factories depend on the part: Neville suits long-profile machining, Bonnell combines machining with welding, Mifa focuses on small precision sections, and 80/20 modifies framing-system components. Zhenling Metal offers drawing-based machining of extrusion stock. Start by deciding whether you need a new extrusion or secondary work on an existing profile.

A factory working with aluminum profiles can still be the wrong supplier for the finished holes, mounting faces or coating. On the other hand, a capable machining manufacturer may purchase the extrusion and leave the pressing to someone else. This analysis will separate those different routes in your list to reflect what you’re actually ordering.

Disclosure: This guide is published by Zhenling Metal. We list ourselves first because this is our website, not because we claim to be the market leader. The other 19 manufacturers are grouped by what they’re best for, in no particular order within each group.

How We Selected These Extrusion Machining Factories

Each company listed here qualifies by aluminum profile machining or fabrication capabilities, with aluminum extrusion manufacturing included where the company describes that route of production. Information was confirmed against the company website and other public sources in October 2026. Trading companies, distributors, sourcing platforms, directories, media websites and used-equipment dealers were excluded. The focus here’s on companies in North America and Europe as well as China, with machining specialists that process extrusion stock.

The top aluminum extrusion companies listed here are application-based, and not ranked by estimated revenues, capacity, or quality of product. Other companies can also qualify; a company not included in this list hasn’t been ranked inferior. Descriptions are based on the published capabilities of companies, with certification statements attributed to the company and facility in question, and scope retained where stated.

Location labels distinguish a headquarters, a manufacturing site and a registered office where the sources differ. Company origins can also differ from legal incorporation: Neville’s registry records 2004, while its history describes a 2006 business restructuring. The distinction avoids giving every date and address a meaning its source doesn’t support.

20 Aluminum Extrusion Machining Factories Compared

The Extrusion-to-Part Supplier Map compares manufacturers by production responsibility and the order each manufacturer is best suited to handle. Aluminum extrusion design and subsequent manufacturing processes define that order. The best-for and limitation columns should be used together. The longest machine, smallest quoted tolerance, or the widest service range only helps when it matches the profile and finished features you need.

Profile Machining and Long-Part Specialists

Machining specialists suit buyers who already have extrusion stock or want secondary processing arranged around an established profile. The factories in this group emphasize long parts, repeated features or drawing-based component manufacture. Their value lies in the machining route, while responsibility for making a new extrusion must be identified separately.

1. Zhenling Metal: Best for drawing-based machining of supplied or sourced extrusion stock

Location: Jiashan, Zhejiang, China (manufacturing plant); founded in Shanghai · Founded / origins: 2006 · Type: Custom component machining manufacturer

Official website: https://zhenlingmetal.com/

Main products: CNC-milled and turned aluminum parts, drilled and bored components

Certifications / stated scope: CE and ASME certification stated on its website for pressure-related work

Zhenling's published aluminum machining service accepts plate, bar or extrusion stock, so it fits a buyer who already has a profile design and needs mounting faces, bores, threaded holes or other finished features added to it. The company describes machining, welding and inspection at its own Jiashan plant, with 3-, 4- and 5-axis machining available according to the part geometry. Its CE and ASME statements concern pressure-related work. A new extrusion die and press run require a separately agreed supply route because this is a machining-led offer.

2. Neville Precision Engineering: Best for long aluminum profiles machined without re-indexing

Location: Pinxton, Nottinghamshire, UK · Founded / origins: 2004 legal incorporation; 2006 business restructuring described by the company · Type: Aluminum-profile CNC machining manufacturer

Official website: https://www.nevilles.ltd/

Main products: Long machined aluminum extrusions and custom fixtures

Certifications / stated scope: ISO 9001, ISO 14001 and ISO 45001, according to its website

Neville specializes in precision CNC machining for aluminum extrusions, including long parts whose hole positions would otherwise require moving the workpiece between setups. According to its website, its 4- and 5-axis equipment handles parts from 50 mm to 8000+ mm, and parts over 1000 mm can be machined in one operation without re-indexing. The Pinxton operation accepts free-issue material or sources profiles for the order, a useful route when purchasing already has an extrusion supplier but needs a machining company for the finished features. The business specializes in CNC machining; profile manufacture remains a separate supply responsibility.

3. ABL Aluminium Components: Best for very long profiles with repeated drilled or punched features

Location: Wednesbury, West Midlands, UK (registered office) · Founded / origins: 1998 (current legal entity incorporated) · Type: Aluminum component fabrication manufacturer

Official website: https://www.ablcomponents.co.uk/

Main products: CNC-machined, drilled, punched and bent aluminum components

ABL combines CNC machining with cutting, drilling, punching and bending, giving buyers more than one way to produce repeated features in an aluminum profile. Its fabrication page describes component sizes from 25 mm to 14 m and tools designed internally for the work, including processing of extrusion, casting and sheet metal inputs. That combination is relevant to long rails or sections with a stable pattern of holes, where production may mix a CNC operation with a dedicated punch instead of milling every feature individually. The sheet metal fabrication offer sits alongside its profile work. Dedicated punches and fixtures are a less natural fit for designs that change frequently, so CNC processing is the more flexible route within that offer.

4. MA5 Fabrication: Best for lineal-profile operations alongside metal fabrication

Location: Santa Fe Springs, California, USA · Founded / origins: Not stated in reviewed company information · Type: Metal fabrication and machining manufacturer

Official website: https://ma5fab.com/

Main products: Extruded Aluminum Machining, Welding, and Fabrication

MA5’s service menu lists aluminum extrusion machining, CNC milling, CNC turning, welding, laser cutting and tube bending. Milling and turning have different build envelopes, minimum feature sizes and design rules. A buyer evaluating this CNC machine shop route can quote the machining and fabrication operations separately, with the required part geometry stated for each process.

Integrated Extrusion and Assembly Manufacturers

Custom aluminum extrusion services can connect the profile with later fabrication, machining or assembly. These integrated manufacturing services are suited for programs where the cross-section and finished shape are developed conjointly, or where purchasing wants several operations in a given supply route. The comparison remains at plant level, since group capabilities can be dispersed over several plants.

5. Hydro: Best for multi-region extrusion programs with downstream fabrication

Location: Oslo, Norway · Founded / origins: 1905 · Type: Integrated aluminum producer and extruder

Official website: https://www.hydro.com/

Main products: Extruded profiles with machining, forming and joining

Hydro's machining and fabrication offer starts with the profile design and continues through downstream operations, including forming and joining. For a purchasing team placing aluminum extrusion projects across regions, that creates a route to discuss how the extrusion geometry can simplify later machining instead of treating the press and machine shop as unrelated purchases. Its broad aluminum business also makes it relevant when the program needs continuity between material supply, custom extrusion and fabricated components. The practical limitation is plant scope: a group-wide service description doesn’t mean that every Hydro facility has the same machining equipment, finishing operations or assembly capacity.

6. Bonnell Aluminum: Best for North American extrusion programs needing machining and robotic welding

Location: Newnan, Georgia, USA (division headquarters in company history) · Founded / origins: 1950s (William L. Bonnell entity formed) · Type: Aluminum extrusion and fabrication manufacturer

Official website: https://bonnellaluminum.com/

Main products: Machined extrusions and welded aluminum assemblies

Bonnell Aluminum lists 3-, 4- and 5-axis CNC machining with custom clamping, together with robotic welding for fabricated aluminum components. Those capabilities make its offer relevant to a North American program that buys an extrusion as part of a welded or assembled product, where the machining and joining sequence affects the delivered part. A procurement team can therefore compare an integrated robotic welding and CNC machining route with buying separate fabrication services, while keeping the same drawing revision and inspection scope. Availability belongs to the plant assigned to the program; the group description isn’t a promise that every facility performs every operation.

7. Taber Extrusions: Best for wide extrusion sections with value-added machining

Location: Russellville, Arkansas, USA; also Gulfport, Mississippi · Founded / origins: 1973 · Type: Aluminum extrusion and precision-machining manufacturer

Official website: https://taberextrusions.com/

Main products: Wide solid and hollow profiles, machined aluminum components

Certifications / stated scope: ISO 9001 and AS 9100 stated on its website

Taber has a distinct starting point for wide sections: its published history describes solid profiles up to 31 inches wide, and its technology material discusses rectangular-billet extrusion. The company also describes a Haas VF-12 machining center and friction stir welding, so its relevance extends beyond selling an unfinished aluminum shape to buyers evaluating a fabricated structural component. Wide solid and hollow profiles are the reason to investigate this route when a narrow standard extrusion can’t provide the required section. The extrusion width capability doesn’t establish the machining envelope or accuracy of every finished part; those are separate characteristics of the production route.

8. Pennex: Best for extrusion-to-assembly programs with long-bed machining

Location: Pennsylvania, USA; Wellsville operations · Founded / origins: 1979 · Type: Vertically integrated aluminum manufacturer

Official website: https://www.pennex.com/

Main products: Cast billet, extruded profiles, fabricated and assembled aluminum parts

Pennex brings billet casting, extrusion, fabrication and assembly into one manufacturing offer, and its fabrication page specifically lists long-bed 5-axis and horizontal machining centers. The company explains that it extrudes the parts itself and can shape the profile to simplify later fabrication, which is useful when an engineer can still alter wall positions or add material around a mounting feature before the die is released. Buyers comparing finished aluminum parts can therefore discuss both the original profile and the secondary operations within the same program. Its described stretch-forming route uses T4 aluminum, making the temper part of the forming decision as well as the material specification.

9. Exlabesa: Best for large-format profiles with multi-axis machining

Location: Valga and Padrón, Galicia, Spain (Spanish manufacturing centers) · Founded / origins: 1966 · Type: Aluminum extrusion and fabrication manufacturer

Official website: https://exlabesa.com/

Main products: Custom extruded profiles and machined structural components

Certifications / stated scope: ISO 9001:2015 and ISO 14001 displayed for its Spanish manufacturing centers

Exlabesa publishes unusually specific machining information: 34 machining stations with 3, 4 or 5 axes and a maximum envelope of X 21000, Y 600 and Z 310 mm. That gives buyers of long structural profiles a concrete starting point for matching their part length and cross-section to a fabrication route instead of relying on the word large alone. Its Spanish manufacturing centers display ISO 9001:2015 and ISO 14001, while the machining page separates machining capability from saw-cut information. A 21 m axis travel is not a whole-part tolerance guarantee, so the usable envelope and the dimensional acceptance of a finished component remain different specifications.

10. MMG Engineered Extrusions: Best for integrated extrusion, robotic welding and downstream assembly

Location: Franklin, New Hampshire, USA · Founded / origins: 1986 (as Jarl Extrusions) · Type: Integrated aluminum extrusion manufacturer within Momentum Manufacturing Group

Official website: https://mmgextrusions.com/

Main products: Extruded components, fabricated structures and assemblies

Certifications / stated scope: ISO 9001:2015, according to its website

MMG Engineered Extrusions traces its extrusion business to Jarl Extrusions in 1986 and describes a 50,000-square-foot addition in 2020 for machining, fabrication and assembly. The current capabilities include large-format CNC work, robotic welding, tube laser cutting, bending and coating, which make the business relevant when an extrusion becomes a larger fabricated structure. A buyer comparing welding and CNC machining services can examine a combined supply route instead of arranging each operation as an unrelated purchase. The range spans group capabilities, so the production location and process route assigned to the part determine which operations are included in the actual offer.

11. Alexandria Industries: Best for aluminum assemblies that also need molded components

Location: Alexandria, Minnesota, USA · Founded / origins: 1966 · Type: Extrusion and multi-process component manufacturer

Official website: https://www.alexandriaindustries.com/

Main products: Extruded aluminum, precision-machined parts and mixed-material assemblies

Alexandria Industries combines aluminum extrusion and precision machining with plastic injection molding, foam molding, welding and assembly. That’s a useful distinction for a product containing an extruded body plus molded covers or other nonmetal components, because its offer is broader than custom CNC machining of the aluminum alone. Its company-location information separately identifies Alexandria Precision Machining as a 19,000-square-foot facility, illustrating how the group organizes specialized production rather than treating every operation as one machine cell. A mixed-material assembly therefore involves a route across the relevant facilities, which matters when comparing the scope of finished assemblies with a quote for machined aluminum only.

12. FONNOV Aluminium: Best for long profiles supplied as fabricated and finished parts

Location: Zaozhuang, Shandong, China (published contact address) · Founded / origins: 2004 · Type: Aluminum extrusion and fabrication manufacturer

Official website: https://www.fonnovaluminium.com/

Main products: Custom profiles, machined components and assembled structures

Certifications / stated scope: ISO 9001 quality system stated on its website

FONNOV lists CNC machining for profiles up to 30 meters long and describes trial assembly and testing of large structural components. For buyers ordering fabricated profiles from China, that combination is relevant when the delivery needs to include drilled, machined and finished members that fit together, rather than raw lengths that will be processed after arrival. The manufacturer also lists ISO 9001 and positions its service around custom aluminum extrusion profiles with downstream operations. Its published 750 mm width capability applies to suitable shapes, so the maximum width should not be read as an unrestricted cross-section allowance for every long-profile design.

13. Wellste: Best for custom extruded and machined profiles ordered by production weight

Location: Zhenjiang, Jiangsu, China · Founded / origins: Not stated in reviewed company information · Type: Aluminum extrusion and fabrication manufacturer

Official website: https://www.wellste.com/

Main products: Profiles, tubing, heat sinks and fabricated aluminum components

Certifications / stated scope: ISO 9001 and ISO 14001 stated on its About page

Wellste publishes 35 extrusion lines alongside CNC machining, bending, stamping and welding, with aluminum products including profiles, tubing and heat sinks. The company also describes anodizing and powder coating resources, giving a buyer a basis for discussing a finished component rather than a bare extrusion plus separately purchased machining solutions. Its About page lists ISO 9001 and ISO 14001. The published 500 kg minimum for custom extrusion can dominate a small finished-part requirement, even when the individual machining features are simple, so this route fits a production-weight purchase better than a handful of trial pieces.

14. GSH Industries: Best for programs combining aluminum profiles with plastic or rubber components

Location: Strongsville, Ohio, USA · Founded / origins: 1986 · Type: Custom extrusion and fabrication manufacturer

Official website: https://www.gshindustries.com/

Main products: Aluminum, plastic and rubber profiles with secondary fabrication

GSH combines aluminum extrusion fabrication with plastic and rubber extrusion, which makes it relevant to assemblies that use a metal frame together with seals, flexible sections or polymer profiles. Its aluminum page lists 6063, 6061, 6463 and 6105, plus CNC milling, cutting, punching, bending, welding and deburring as secondary operations. Buyers can use that material and process range to evaluate a coordinated component program instead of choosing an aluminum extruder without considering the nonmetal pieces of the assembly. The published aluminum profile envelope reaches 10 inches in diameter, which sets a practical boundary for this option when the cross-section becomes larger.

Custom Profiles and Secondary Operations

Custom-profile specialists are relevant when the starting section needs a particular size, wall or precision approach. Published offerings of these plants are very heterogeneous. For complex aluminum parts, match the extrusion envelope to the drawing and the secondary operation before selecting a route.

15. Mifa Aluminium: Best for miniature thin-wall precision profiles with secondary machining

Location: Venlo, Netherlands · Founded / origins: 1975 · Type: Precision extrusion manufacturer within Aalberts

Official website: https://mifa.eu/

Main products: Precision aluminum profiles with machining and surface treatment

Certifications / stated scope: AS 9100D stated on its website

Mifa focuses on precision aluminum extrusion and publishes small-profile capabilities that include diameters from 3 to 180 mm, wall thickness from 0.25 mm and extrusion tolerances starting at ±0.02 mm. Machining, surface treatment and assembly extend that offer into precision machined parts, which is useful when a small, repeated section would otherwise require substantial material removal from solid stock. Its website states AS 9100D, and the business identifies itself within Aalberts, with company origins in 1975. The starting extrusion tolerance depends on the profile; it isn’t a blanket tolerance for every feature of an assembled or machined part.

16. Profile Precision Extrusions: Best for miniature extrusions and small machined features

Location: Phoenix, Arizona, USA · Founded / origins: 1982 roots; current Profile Precision Extrusions name from 2001 · Type: Miniature aluminum extrusion and machining manufacturer

Official website: https://profileprecisionextrusions.com/

Main products: Small custom extrusions, medical profiles and machined components

Profile Precision Extrusions describes three extrusion presses at its Phoenix factory, with a third press added during its move into a larger facility, and offers machining for miniature custom profiles. Its fabrication page distinguishes small-part 3-axis work from a separate 4-axis machine for profiles up to 14 feet long, so a buyer can identify the route that matches the part instead of comparing only the longest advertised length. The page associates a 0.0002-inch figure with the small-part setup, while its history separates 1982 business roots from the current name adopted in 2001. That small-part figure must not be transferred to the long-bed machining route.

17. Richardson Metals: Best for small and medium runs of compact custom profiles

Location: Colorado Springs, Colorado, USA · Founded / origins: 1980 · Type: Custom extrusion and precision-machining manufacturer

Official website: https://www.richardsonmetals.com/

Main products: Custom aluminum profiles and machined precision parts

Richardson Metals builds its offer around compact custom shapes and low- to medium-volume work, with a published 550-ton extrusion press. Its current About page describes added 4- and 5-axis CNC machines, extending the route from custom profile manufacture into machined precision components rather than requiring the buyer to source the secondary work separately. The listed extrusion diameter range reaches 4 inches, making the company relevant to smaller sections whose custom cross-section can reduce rough machining. Alloy, shape, wall thickness and weight still constrain that envelope, so this is a compact-profile option rather than a large structural-extrusion substitute.

18. PSI Industries: Best for profiles with finishing and light assembly

Location: Irving, Texas, USA; extrusion facility in Olney, Texas · Founded / origins: 1985; first extrusion press built in 1987 · Type: Custom aluminum extruder and fabricator

Official website: https://www.psiextrusions.com/

Main products: Extruded and machined aluminum parts with anodizing, coating and assembly

Certifications / stated scope: ISO 9001:2015 and AS9100D stated on its website

PSI describes an in-house route covering extrusion, 3- and 4-axis machining, lathes, anodizing, coating and light assembly, with its corporate location in Irving and extrusion production in Olney. The company website lists ISO 9001:2015 and AS9100D, while its history distinguishes the 1985 opening from construction of its first extrusion press in 1987. That combination suits a buyer who needs custom profiles delivered with secondary features and a specified surface condition. Its coating information describes a 30-foot oven but parts only up to 12 feet long, so the oven dimension cannot be used as the maximum finished-part length.

19. Anaheim Extrusion: Best for slide-fit and snap-fit profiles with drilled and tapped features

Location: Anaheim, California, USA (facility location) · Founded / origins: Not stated in reviewed company information · Type: Extrusion and fabrication division of Universal Molding Company

Official website: https://www.anaheimextrude.com/

Main products: Tubing, bars, rods and slide-fit or snap-fit electronic profiles

Anaheim Extrusion identifies itself as a division of Universal Molding Company and lists in-house cutting, drilling, countersinking, punching, notching, tapping and welding. Its product range includes tubing, bars and rods as well as slide-fit and snap-fit electronic profiles, with both short and long runs described on the website. A buyer whose component needs a custom section plus straightforward holes and assembly features can therefore compare it with a CNC-focused supplier on the actual required operations. Custom shapes involve a separate die-engineering and tooling step: the company makes dies to the buyer’s specifications using the supplied design files.

Framing-System Machining

Framing-system machining typically relies on a catalog of structural profiles and connections rather than a completely free-form custom section. This method can be useful for equipment frames, guards and workstations when a large portion of the structure is standard, and the remaining features are custom. This allows the buyer to adapt components in an established assembly system.

20. 80/20: Best for T-slot framing components with in-house custom machining

Location: Columbia City, Indiana, USA · Founded / origins: 1989 · Type: Modular framing manufacturer with in-house custom machining

Official website: https://8020.net/

Main products: T-slot profiles, brackets, fixtures and custom machined components

80/20 combines a modular framing catalog with an in-house custom machining team that can modify profiles, brackets and fixtures without outsourcing the machining. Its published offer covers more than 200 stock structural shapes and states no minimum charges or minimum runs for custom machining, making it relevant to machine frames, workstations and other industrial and commercial applications built around a known framing system. Company history places its founding in 1989 and later move to Columbia City, Indiana, giving a clear identity behind the familiar system name. Selecting and modifying catalog sections is a different purchasing route from commissioning an unrestricted custom extrusion die.

How to Choose an Extrusion Machining Factory

Select an extrusion machining factory based on the finished part and the route to make it. Begin with who supplies the profile, and then evaluate access to machining, dimensions, finish, and delivery. A short list connects responsibility to a named facility and a drawing, rather than comparing vague statements of precision manufacturing.

For a broader search across aluminum parts cut from plate, bar or billet, use our aluminum CNC machining factory comparison. The criteria below address the additional questions created by an extruded starting shape.

1. State what starting material the factory will use. Will the factory buy a standard section, create a custom die, or machine free-issue profiles? A custom aluminum extrusion manufacturer and a secondary processor can quote the same part with different materials and tooling responsibility.
2. Separate profile size from machine access. Supply the cross-section, finished length and feature locations. Automotive or equipment-assembly requirements should be expressed as drawing features and acceptance criteria rather than industry labels alone. Exlabesa’s published X 21000 mm travel and Mifa’s small-profile range answer different questions; neither figure alone establishes whether a particular pocket, end face or angled hole can be reached.
3. Define dimensions in their finished condition. Identify datums and critical relationships between features, including dimensions measured across separate setups. Our comparison of three-, four- and five-axis machining explains why axis count should be tied to geometry and access.
4. State alloy and temper. For a general-purpose industrial profile order from China, GB/T 6892-2023 is a relevant standard to identify with the supplier. The official version states it is the current version. ASTM B221-21 is a different specification that is shown as currently active by ASTM. Do not assume they are interchangeable or that naming either establishes conformity.
5. Define responsibilities for finishing and joining. Make decisions about which facility will weld, anodize, or coat a component, and what will be done in-house. A full-service description requires the assignment of a process route. Provide information about the treatment of cosmetic surfaces, masked holes, and bonded areas, as these determine the sequence of machining operations.
6. Verify once. Check evidence at the supplier-approval level. Review the current certificate scope, the first article inspection plan, the material traceability, and any special processes outsourced. Management system certification belongs to a named organization and scope; it doesn’t by itself certify that every machined product or dimensional claim is dimensionsally correct.
7. Compare the material commitment with the part release schedule. A minimum profile purchase by weight can exceed an initial order for finished components. Wellste’s published 500 kg custom-extrusion minimum illustrates why the extrusion order and the machining batch should appear separately.
8. Include delivery conditions. Deburring and surface protection, as well as the requirements for packing and inspection should be included along with the part price. Long finished profiles may require a different delivery arrangement than short blanks, especially when exposed faces of the long profiles must be ready for assembly.

How do I specify surface finish for a machined aluminum extrusion?

Specify the required appearance and dimensions of the finished part. Indicate visible faces, contact surfaces, and threads. Indicate areas to be masked. An extrusion surface and a freshly machined face may have differing textures, so the name of the color alone may not indicate the required appearance of the assembled part.

For an anodized part, state whether machining precedes anodizing and whether any features need protection or later processing. Include a sample or agreed visual reference when appearance matters, and state any corrosion resistance requirement separately from color. Our anodizing service information provides context for discussing surface treatment alongside dimensional requirements. Powder coating belongs in the same drawing review when coverage, masking or assembled fit is important.

When Does Extrusion Plus Machining Beat Billet Milling?

Extrusion and subsequent machining may be economical compared to milling a billet if a significant amount of rough machining is required. Continuous profile is created by a custom die, and local features (pockets and details at the end of the part) are machined afterwards. The commercial choice depends on the design, tooling commitment and repeat demand; there is no universal break-even quantity.

The aluminum extrusion process forms a section that repeats along its length. If your part is made up of this section along its length, a near-net shape may require less material to be removed during the finishing operations (aluminum machining). A constant section does not create every finished feature, however: cross-holes, localized pockets and many end connections still need separate operations.

Billet milling is easier to compare when the design is changing, the order is small or there’s no useful repeated cross-section. The buyer avoids committing to an extrusion die, although the machining route may remove more material. Our CNC milling service covers drawing-based parts for which a solid starting shape remains a practical option.

A prototype should answer the design question that really matters. A billet machined sample can help check the fit, but it does not demonstrate the exact extrusion surface, profile tolerances or production sequence of a later extruded part. Keep that distinction visible when moving from a sample into volume production, particularly if the design includes thin walls or a cosmetic anodized face.

What Should an Extrusion Machining Quote Include?

An extrusion machining quote should encompass the price of a completed part, including material, tooling, other operations, and delivery. Provide a cross section of the profile and a drawing of the completed part. Separate one-time costs from recurring costs, and show the planned order quantities and releases to allow suppliers to compare equivalent manufacturing routes.

Start with the latest drawing revision and a model where available. Mark the dimensions that control assembly, then describe the alloy and temper, finish and quantity schedule. For parts with angled access or several machined faces, the five-axis machining service scope is useful context for a drawing review; buying more axes isn’t an objective by itself.

• Material and tooling: standard or custom profile, alloy, temper, extrusion-die cost, machining fixtures and ownership of reusable tooling.
• Operations: cut lengths, milling, drilling, tapping, deburring, forming, welding, finishing and any light assembly.
• Quantity: minimum extrusion purchase, initial finished-part batch, expected repeat quantities and release schedule.
• Approval: sample or first-article scope, critical inspection records and the drawing revision used for acceptance.
• Commercial delivery: recurring unit price, lead times, packaging, shipment and responsibility for outsourced processes.

How much does custom aluminum extrusion cost?

The cost of a custom extrusion includes the extrusion profile and tooling, and other downstream operations. A quotation for a profile may not include CNC machining, surface finishing, inspection and packing, and a quotation for a completed part may include those operations. Separate the extrusion die and machining fixtures, and evaluate recurring costs at the same quantity.

Small batches of repeated orders and large production runs create different material requirements, even with an identical drawing for the completed part. For mass production orders, ask for those commitments to be clearly stated, rather than inferring them from a unit price. Quick turnaround also needs a defined starting point: available stock, an approved die and a new custom die are different production situations.

An analysis of purchases is helpful without a speculative savings percentage. Place the offers next to the same drawing, and determine what each includes. Sometimes there appears to be a price difference due to missing operations or different levels of inspection. Comparability of prices of metal manufacturing becomes evident once scope differences are understood.

Frequently Asked Questions

Typical sourcing questions are about long profiles, the distinction between extrusions and machining, the size of the companies, and the route of manufacture. The following distinguish suppliers’ published capabilities from the judgment of the purchaser. They are intended to help narrow a shortlist before a drawing-based quotation, without assigning one factory’s dimensions or conditions to another.

Request a Drawing-Based Machining Review

Zhenling Metal can review a drawing for custom manufacturing of finished components from aluminum extrusion stock. Send the profile cross-section, part drawing, material, finish and quantity schedule so the discussion starts with the required result. If the project needs a new extrusion die, identify that requirement separately from the machining and finishing scope.

Our aluminum CNC machining service describes the materials and operations available for a drawing review. You can also read about the Jiashan manufacturing operation behind that service. The next useful step is a defined part and an agreed supply route, rather than choosing a factory solely from a headline capacity.
