Langhe Casting provides high-precision POM CNC machining services tailored for performance-critical applications. Known commercially as Delrin or Acetal, POM offers excellent dimensional stability, low friction, and high wear resistance—ideal for engineering components where metal replacement is desired.
Polyoxymethylene (POM) is a semi-crystalline thermoplastic offering strength, stiffness, and machinability similar to soft metals. It performs exceptionally well in low-lubrication environments, making it ideal for parts such as gears, bushings, and valve components.
