What is Delrin (POM)?

Delrin, also known as POM (Polyoxymethylene) or Acetal, is a high-performance engineering thermoplastic widely used in precision CNC machining.

It offers an excellent balance of mechanical strength, low friction, and dimensional stability, making it an ideal choice for tight-tolerance components across automotive, industrial, and consumer applications.

High Strength

Excellent stiffness and toughness for structural parts.

Low Friction

Ideal for moving components and wear-resistant applications.

Dimensional Stability

Maintains tight tolerances even in varying environments.

Low Moisture Absorption

Performs reliably in humid or wet conditions.

Delrin (POM) CNC Machining Capabilities

CNC Milling

3-axis, 4-axis, and 5-axis milling for complex geometries and tight tolerances.

CNC Turning

Precision turning for shafts, bushings, bearings, and custom cylindrical parts.

Complex Geometries

Expert at undercuts, threads, slots, holes, and intricate features.
