HDPE Machining vs Molding Cost Planner
Use actual supplier quotes to calculate the economic crossover. No universal volume is assumed.

Molding total at quantity

Calculated crossover
—
Enter both supplier routes to compare totals.
Formula: crossover quantity = (molding one-time cost − machining one-time setup) ÷ (machining unit cost − molding unit cost). The model compares quoted cost only; geometry, material equivalence, draft, tolerances, qualification, scrap, logistics and capacity still require review.
Need a machining quote for the comparison? Send the same revision, material, quantities and acceptance state used in the molding RFQ.
