Why Choose POM for CNC Machining?

  • Exceptional Machinability
    POM stands out with its ease of machining, which includes CNC operations, injection molding, and extrusion. This quality makes it possible to achieve high precision and complex geometries effortlessly.
  • Superior Mechanical Properties
    With outstanding tensile strength and impact resistance, POM can handle high-load applications making it ideal for manufacturing robust mechanical components.
  • Low Friction Coefficient
    The low friction coefficient of POM allows for operation under unlubricated conditions, minimizing wear and extending the lifespan of components.
  • Excellent Chemical Resistance
    POM’s resistance to various chemicals, fuels, and lubricants enhances its durability and suitability across multiple environments without the risk of corrosion.

Advanced POM Machining Techniques

  • Milling and Turning
    Remove excess material with precision using advanced milling and turning processes, perfect for crafting intricate parts and prototypes.
  • Laser Cutting
    For complex patterns and fine details, laser cutting offers a high-precision method that ensures smooth, clean edges.
  • Injection Molding
    Ideal for mass production, this technique involves melting and injecting POM pellets into molds to quickly and efficiently create large volumes of complex parts.

POM Parts with Expert Finishing Techniques

  • Sandblasting
    This process treats the surface of POM parts to create a uniform matte finish that increases friction and enhances tactile qualities.
  • Polishing
    Achieve a smooth and glossy surface through mechanical, chemical, or electrochemical polishing methods that enhance the aesthetic and tactile appeal of POM components.
  • Spraying
    Apply paints or coatings to POM surfaces to introduce color variety, improve protection, and boost aesthetic value.
  • Laser Engraving
    For durable and precise markings, laser engraving allows adding custom patterns, text, or logos to POM parts, combining high accuracy with resistance to wear.
