POM CNC Machining

POM (Polyoxymethylene) is an engineering thermoplastic product that demonstrates superb dimensional stability, tightness impact, and temperature level 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. Along with its remarkable mechanical buildings, CNC-machined acetal offers superior dimensional security that makes it perfect for high-precision parts.

POM materials are typically used in the manufacture of pipeline elements, equipment bearings, household devices, automotive components, consumer electronic devices, 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.
