POM (Acetal / Delrin) in CNC Machining
POM (polyoxymethylene), also called acetal, is a strong, dimensionally stable engineering thermoplastic with good machinability and wear performance. RapidDirect offers POM for CNC machining and injection molding for automotive, electronics, consumer products, and industrial machinery.
- Strength and rigidity: POM supports functional parts under mechanical loads.
- Dimensional stability: The material helps maintain precise dimensions.
- Wear performance: POM suits moving components and repeated contact.
- Machinability: CNC machining produces detailed custom POM parts.
Selection note: POM’s combination of strength, dimensional stability, and machinability makes it suitable for precision mechanical components. Delrin is a familiar brand name for acetal grades.
