CNC Machining Polycarbonate Delrin and Nylon

In the precisiondriven world of part manufacturing, material selection is as critical as the machining process itself. For components requiring exceptional dimensional stability, specific mechanical properties, and resistance to various environmental factors, engineering plastics like Polycarbonate (PC), Delrin (POM), and Nylon (PA) are outstanding choices. As a professional onestop CNC machining service, we specialize in transforming these versatile polymers into highperformance, reliable parts that drive innovation across industries.

Polycarbonate (PC): Unmatched Toughness and Clarity

Polycarbonate is renowned for its incredible impact strength and optical clarity. It is significantly stronger than acrylic and offers good heat resistance, making it ideal for applications that demand durability and transparency. Common uses include protective guards, lenses, light diffusers, and medical device components. However, PC is susceptible to scratching and can be attacked by certain chemicals. Our CNC machining expertise allows us to work with PC efficiently, minimizing internal stresses and achieving the required optical quality or structural integrity without compromising the material's inherent properties.

Delrin (POM): The Precision Machinist's Dream

Delrin, or Polyoxymethylene, is a highperformance acetal homopolymer. It is the goto material for parts requiring low friction, high stiffness, and excellent dimensional stability. Delrin machines exceptionally well, producing clean, sharp edges and smooth surfaces with minimal postprocessing. Its low moisture absorption makes it perfect for components that must operate reliably in humid environments. Typical applications include gears, bearings, bushings, and intricate insulators. Our CNC mills and lathes are perfectly suited to harness Delrin's properties, delivering parts with tight tolerances and superior wear resistance.

Nylon (PA): Versatile Strength and Wear Resistance

Nylon is a family of synthetic polymers known for their good strength, toughness, and excellent resistance to abrasion and wear. With various grades available (such as PA 6, PA 66, and MC Nylon), it offers a wide range of properties, including the ability to be fiberglassfilled for added rigidity. Nylon parts often serve in demanding applications like custom fasteners, pulleys, and structural components. A key consideration is its tendency to absorb moisture, which can affect dimensions. Our skilled machinists understand how to manage this, often performing secondary drying processes or factoring in moisture expansion to ensure final parts meet exact specifications.
