High Strength Plastic Gears, Small Plastic Wheel Gears, Gear Mould

The high strength plastic gears, small plastic wheel gears, and gear mould discussed here are made from nylon PA6 sheets and rods. These products are manufactured by Guangzhou Engineering Plastics Industries (Group) Company using 100% virgin raw material. The nylon PA6 sheets and rods exhibit excellent performance characteristics such as toughness even at low temperatures, high hardness on the surface, mechanical shock resistance, and abrasion resistance. Additionally, they possess good insulation and chemical properties, making them widely used in various mechanical structures and spare parts.


  1. Good tensile strength
  2. High impact and notching impact strength
  3. High heat deflection temperature
  4. High strength and stiffness
  5. Good glide and limp home characters
  6. Good chemical stability against organic solvents and fuels
  7. Resistant to thermal aging (applicable temperature between -50°C and 110°C)
  8. Size alternation by humidity absorption must be considered


  • Nylon PA6 products from Guangzhou Engineering Plastics Industries (Group) Company are widely used as wear parts of mechanical equipment or as quick-wear parts instead of copper and alloy.
  • They can be used for shaft sleeves, bearing bushes, linings, lining plates, gears, worm gears, roller copper guide rails, piston rings, seal rings, slide blocks, spheric bowls, impellers, blades, cams, nuts, valve plates, pipes, stuffing boxes, racks, belt pulleys, pump rotors, and more.
