FAQs About Custom POM (Delrin/Acetal) CNC Machining Parts
What is POM (Delrin/Acetal)?
POM is a high-performance engineering thermoplastic known for its strength, stiffness, and low friction.
What are the differences between POM-H (homopolymer) and POM-C (copolymer)?
POM-H has higher strength and stiffness, while POM-C offers better thermal stability and chemical resistance.
Can POM parts be used in food or medical applications?
Yes, FDA-compliant POM grades are available for safe contact with food and medical devices.
Can POM (Polyoxymethylene) be laser-cut?
POM can technically be laser-cut, but it is generallynot recommended. When exposed to a laser, POM may releaseformaldehyde gas, which is hazardous and can damage equipment. For precision parts,CNC machining (milling or turning)is the preferred and safer manufacturing method.
Is Delrin stronger than nylon?
In many cases,Delrin (POM)is stronger and stiffer than nylon. It offershigher dimensional stability, lower friction, and better wear resistance. However, nylon typically hasbetter impact resistance and higher temperature tolerance, depending on the specific grade.
Can POM be used for outdoor applications?
POM can be used outdoors forshort-term applications, but it haslimited UV resistance. Long-term exposure to sunlight may cause degradation and reduced mechanical properties. For outdoor use,UV-stabilized grades or protective coatingsare recommended.
How does POM differ from other plastics (such as ABS or nylon) in terms of processing properties?
POM machines very well and producesclean chips and smooth surfaces during CNC machining. Compared with ABS, POM hashigher strength, stiffness, and wear resistance. Compared with nylon, POM haslower moisture absorption and better dimensional stability, making it ideal for precision mechanical components.
Is POM suitable for high-temperature environments?
POM is not ideal for high-temperature environments. Its typicalcontinuous service temperature ranges from about 80°C to 100°C, depending on the grade. At higher temperatures, the material maydeform or lose mechanical strength.
Which colors of POM are available for CNC machining?
Common POM colors for CNC machining includenatural (white or milky), black, and sometimes blue or other custom colorsdepending on the manufacturer. Natural and black POM are themost widely used grades for industrial applications.

The manufacturer is strongly recommended. In the past few years of cooperation we have ordered several machined products from aluminum and stainless steel. These products are manufactured in compliance with tolerance requirements and require product finish. Now I have ordered another one. The service is excellent and any questions can be answered and resolved in time.
2021-05-13
The dimensions are all customized according to my drawings no tolerance issues and the parts are delivered on time. I am very satisfied with it.
2021-04-06
I pay much attention to the surface treatment aspect of this product. I was a little worried about the cooperation at the beginning. I am very satisfied with the product now and hope to cooperate for a long time.
