POM / Delrin acetal
- Alternative Designations: Acetal homopolymer
Colors:
- Black
- White
Description:
This material is an easy resin for molding. It has a relatively high tensile strength as well as high resistance to wear, creep and warp. It is generally durable and tough with low moisture absorption. Furthermore, it is resistant to chemicals such as hydrocarbons and solvents. It is used for a wide range of industrial and mechanical parts such as pumps, valves, bearings, fittings etc.

CNC machined part without surface finishes (3D render, aluminium)Bead blasting (3D render)
Bead blasting
Bead blasting involves spraying a pressurised stream of tiny beads of media, plastic or glass beads, from a nozzle onto the surface of the part. This removes the burrs and imperfections, leaving a smooth finish.
Notes:The recommended part size is 6-600 mm in both height and width. Smaller parts are hard to hold and tough to produce an even surface.
Final result:
- Uniform, matte or satin-like appearance
- Slightly grainy in the touch
-
SPI
SPI finishes are a set of standard mould finishes with different polished textures for enhanced properties.
Notes:A1, A2, A3, B1, B2, B3, C1, C2, C3, D1, D2, D3
Final result:
- Heavily polished, to semi-gloss to fine and coarse matte depending on the selection
-
VDI
VDI is an international standard for mould texturing of matte surfaces. It is mainly processed by Electrical Discharge Machining (EDM) when mould machining.
Notes:VDI12, VDI15, VDI18,VDI21, VDI 24, VDI27, VDI30, VDI33, VDI36, VDI39, VDI42, VDI45
Final result:
- Fine-to-coarse grain depending on the selection
-
Custom Finishing
If you select a custom finish in the Instant Quoting Engine it will require manual review. Manual quoting usually takes 1-2 business days.
Notes:Submitting for manual review with a custom request does not guarantee a quote.
