Acetal / POM (Delrin)

A precision engineering plastic molded for parts that need to hold tight dimensions and slide smoothly.

Example: molded Acetal / POM (Delrin)

What is it?

A low-friction, dimensionally stable engineering plastic, molded rather than machined for higher-volume parts.

Key behavior

Excellent dimensional stability and a naturally slick surface, ideal for parts that move against each other.

Why choose it

Gears, bushings, and snap-fits that need to hold precise dimensions and low friction at volume.

Applications

Precision gears, snap-fit assemblies, bearings, medical device components.

Processing notes

Higher mold shrinkage than many plastics — tooling needs to account for this during design.
