POM CNC Machining
POM (Polyoxymethylene) is an engineering thermoplastic product that demonstrates superb dimensional stability, tightness, impact resistance, and temperature resistance.
The material is also referred to as acetal or Delrin. Delrin is the DuPont brand name for homopolymer acetal. It has far better mechanical residential properties than acetal copolymer with a notable renovation in influence resistance.
Learn the difference between acetal and Delrin.
Along with its remarkable mechanical buildings, CNC-machined Delrin offers superior dimensional security that makes it perfect for high-precision parts.
POM materials are typically used to manufacture pipeline elements, equipment bearings, household devices, automotive components, consumer electronics, and more.

Cost-saving Design Tips
Acetal (Delrin) is one of the extra expensive plastics on the market. It is essential to adhere to the cost-saving principles listed below.
1. Design to basic dimensions:
Acetal is generally provided in sheets of standard densities or in extruded kinds such as strong bars.
2.Do not go for minimum wall surface density:
Although possible, minimum wall surface densities may be tough to component and reproduce without flex, warp, or chatter, and can drive prices up.
FAQs
Yes, because Delrin can easily be removed by the laser beam, it is especially useful for laser cutting or engraving.
Nylon is a strong and durable plastic, applicable to a wide variety of purposes, however it is not as strong as Delrin.
