Delrin® Machining

Delrin® is a brand name for the material known as polyoxymethylene, polyacetal, or just acetal. It’s a low friction polymer that is quite strong and stiff.  As a result of these properties it has the benefit of being dimensionally stable. Delrin is naturally white in color but it is available in different pigmented colors.

Some of the reasons for choosing Delrin® include:

  • Relatively low cost
  • Wide temperature range
  • High mechanical strength and rigidity
  • Good insulator for electrical applications
  • Excellent fatigue endurance
  • Resists moisture, solvents, gas, and numerous neutral chemicals
  • Resilience and resistance to creep
  • Can resist multiple impacts
  • Lubricity

Custom Delrin® Parts for a Variety of Applications 

Delrin is a popular choice for manufacturing many precision components as it is relatively soft but retains stiffness during CNC machining. Finished parts retain their dimensions because of its high stability across a large temperature range.

Machining Delrin plastic is often used to produce:

  • Gears
  • Safety restraints
  • Medical devices.
