Engineering plastics guide for lightweight custom parts

Why use engineering plastics

Engineering plastics can reduce weight, provide insulation, lower friction or protect mating metal components in assemblies.

Selection checklist

  • Define temperature, chemical and moisture exposure.
  • Avoid applying metal-style tolerances to unstable plastic features without review.
  • Choose material based on wear, stiffness, friction and machinability.

Typical parts

Examples include sliding guides, spacers, electrical insulators, bearing pads, protective blocks and low-volume housings.
