POM (Delrin/Acetal) FAQs

  • Can Delrin be machined?

    Delrin can be used in cnc machining. It is a good plastic for applications that will experience lots of friction, require tight tolerances, or need a high stiffness material.
  • Can you laser cut Delrin?

    Yes, because Delrin can easily be removed by the laser beam, it is especially useful for laser cutting or engraving.
  • How do you cut Delrin plastic?

    It’s possible to cut Delrin with a bandsaw, RAS, miter saw, or lathe.
  • Is Delrin stronger than nylon?

    Nylon is a strong and durable plastic, applicable to a wide variety of purposes, however it’s not as strong as Delrin.
