Nylon in CNC: Learn About All Types and Applications

nylon parts for CNC

Nylon is a widely used synthetic polymer, known for its strength, durability, and chemical resistance. In CNC machining, nylon offers versatility across various applications. Here’s a streamlined overview of the key nylon types and their properties.

Nylon 6 (PA 6): Lightweight and Tough

Nylon 6 is synthesized from caprolactam and is known for its tensile strength, abrasion resistance, and elasticity. However, it absorbs moisture, which may impact dimensional stability. With a melting point of 428°F (220°C), it’s ideal for:

  • Gears and bushings
  • Automotive engine covers and intake manifolds
  • Electrical insulators and connectors

Nylon 6/6 (PA 66): Superior Strength and Wear Resistance

PA 6/6, made from adipic acid and hexamethylenediamine, offers higher tensile strength, reduced moisture absorption, and a melting point of 500°F (260°C). Applications include:

  • High-performance mechanical components
  • Glass-filled options for enhanced strength

Nylon 6/12 (PA 6/12): Moisture-Resistant

With alternating monomers, PA 6/12 absorbs less moisture, making it dimensionally stable. Common uses:

  • Fuel lines and electrical sheathing
  • Zippers and outdoor equipment

Nylon 11 (PA 11): Sustainable and Impact Resistant

Derived from castor oil, PA 11 is eco-friendly and excels in flexibility, UV resistance, and low-temperature impact resistance. It’s often used in:

  • Sporting goods
  • Snap-fit parts and hinges

Nylon 12 (PA 12): Chemically Resistant

PA 12 is a linear aliphatic polyamide with excellent chemical resistance and dimensional stability. Applications include:

  • Medical components and automotive fuel systems
  • Enclosures and fixtures

Enhancing Nylon Properties: Fillers

Fillers such as glass and minerals improve strength and dimensional stability. Popular options include:

  • Glass-filled nylon for mechanical strength (e.g., Vydyne R533H)
  • Mineral-filled nylon for stiffness (e.g., Minlon 10B40)
  • UV-stabilized and impact-modified nylons

Choosing the Right Nylon in CNC

Nylon’s adaptability makes it a preferred material for CNC machining. Consulting with your manufacturing team ensures optimal material selection for your project, minimizing wear and maximizing performance.
