Finishes for Acetal CNC Machined Parts
Acetal parts typically have a smooth, glossy finish straight from machining due to the material’s natural properties. Common finishing options include:
Bead Blasting
Metals or plastics parts surface is left with a smooth, matte appearance, with no thickness removal specified.
As Machined
This finish retains visible tool marks and is suitable for both metals and plastics. There is no specific thickness removed in this finish.
Painting
Available for metals and plastics, this finish can be matte, gloss, or textured, with color matching possible.
What is Acetal?
Acetal, chemically known as polyoxymethylene (POM), is a high-strength, crystalline thermoplastic prized for its exceptional stiffness, low friction, and dimensional stability.
Commonly sold under trade names like Delrin®, Tecaform®, and Sustarin®, Acetal is widely used for precision CNC-machined components such as gears, bushings, bearings, and pump parts across automotive, electronics, and industrial applications.
