Acetal homopolymer — an engineering plastic that machines cleanly with sharp tools, holds tight tolerances well, and has low friction and good dimensional stability. Common for gears, bushings, and low-friction wear parts. Sensitive to excess heat from dull tools or high speeds.
These are the preset values this tool starts from — every one is editable in the settings panel once you load a file. They're cncquoter's own defaults, not a market survey.
A plain 40 × 30 × 10mm block in Delrin (Acetal), 3mm stock allowance per side, 2 estimated setups, cncquoter's default shop rate ($95/hr, 25% margin) — computed live by the same cost model at each quantity:
| Quantity | Price / part | Total |
|---|---|---|
| 1 | $125.72 – $209.54 | $125.72 – $209.54 |
| 10 | $13.28 – $22.14 | $132.84 – $221.40 |
| 100 | $2.04 – $3.40 | $203.98 – $339.96 |
This is one fixed sample shape for comparison across materials — your actual part's size, geometry, and setups will change every number here.
