POM is suitable for CNC machined plastic parts that require low friction, wear resistance, good stiffness and stable dimensional performance.
Low friction – Suitable for sliding and moving components.
Wear resistance – Commonly used for bushings, rollers and guide parts.
Good machinability – Suitable for CNC milling, turning, drilling and tapping.
Dimensional stability – Useful for precision plastic components when tolerances are reviewed properly.
Delrin is a brand name for acetal homopolymer, while POM is the general material family name for acetal plastics. Both are used for precision machined plastic parts with good stiffness, low friction and wear resistance.
Material selection depends on mechanical strength, dimensional stability, application environment and customer drawing requirements.
POM parts are more sensitive to temperature, humidity and part structure than metal parts. General tolerances are usually around ±0.05 mm to ±0.10 mm, while tighter tolerances such as ±0.02 mm may be possible for selected features after engineering review.
Xintao checks key dimensions, holes, threads and fitting surfaces before shipment, with inspection reports available when required.
