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.

Delrin CNC Machining FAQs

Common questions about CNC machining Delrin / POM parts, including tolerances, applications, materials, and quote requirements.

Is Delrin suitable for CNC machining?

Yes. Delrin, also known as POM or acetal, is one of the most commonly machined engineering plastics. It machines cleanly, holds good dimensional accuracy, and is suitable for gears, bushings, rollers, spacers, guides, and other functional mechanical parts.

What tolerances can CNCTAL achieve for Delrin parts?

For many Delrin CNC machined parts, we can achieve tight tolerances up to ±0.01 mm depending on the part structure, wall thickness, feature size, and drawing requirements. For plastic parts, we always recommend confirming critical dimensions before production.

What are the advantages of Delrin compared with other plastics?

Delrin offers low friction, good wear resistance, high stiffness, stable dimensions, and low moisture absorption compared with many general plastics. It is often selected for moving parts or precision plastic components that need smooth operation.

Can you machine both white and black Delrin?

Yes. We can machine natural white Delrin and black Delrin depending on your application and appearance requirements. Other POM grades may also be available based on project needs.

What file formats should I send for a Delrin CNC machining quote?

Please send 3D files such as STEP or STP, together with 2D drawings in PDF format if tolerances, threads, surface finish, or inspection requirements are important. Quantity, material color, and application details will help us quote more accurately.

Do you support prototype and small batch Delrin parts?

Yes. CNCTAL supports one-off prototypes, small batch production, and repeat orders for Delrin CNC machined parts. This is useful for product testing, machine maintenance, custom equipment, and low-volume industrial components.
