Nylon Injection Molding

Molded nylon parts provide high strength, temperature, and chemical resistance

There are many types of molded nylon materials, each with its own advantages. For example, nylon 6/6, offers great hardness, stiffness, and abrasion resistance, while nylon 6 is extremely hard and tough at low temperatures, and nylon 6/12 has better impact strength.

  • Nylon 66: General purpose nylon, with a tensile strength of approximately 12,000 psi, high melting point, and mold temperatures ranging from 100 °F-225 °F (38 °C-107 °C)
  • Nylon 46: Heat stabilized and RoHS compliant injection molding processing nylon with very high thermal detection, melting temperature, and mold temperature
  • Filled nylons: High stiffness-to-weight ratio, strong mechanical properties, one of the strongest plastics available for the molding process
    • Mineral-filled nylon: 40% mineral reinforced nylon 66 with a melting point of 505 °F (263 °C), >600 electrical CTI, and HB (‘self-extinguishing’) flammability rating
    • Glass-filled nylons: Options include 13%, 14%, 15%, 20%, 33%, 35% filled and offer high tensile strength and Rockwell hardness with extremely high melting points

Nylon Applications

The PA nylon material is strong, with high-temperature strength, especially when reinforced. This material family offers wear resistance and chemical resistance—except to strong acids and bases—and is electrically conductive and shielding, making it useful for electrical and automotive applications including:

  • Cameras
  • Under-hood components
  • Pump parts
  • Gears and bearings
  • Sprockets
  • Fan blades
  • Latches
  • Manifolds
  • Thin-walled features
  • Combs
  • Spools
  • Screws
  • Structural parts (glass filled)
