When mechanical equipment operates, it exerts strong and rapid forces, requiring its components to be sturdy and stable. If plastic materials are chosen for these components, they must possess the characteristics of high mechanical strength and wear resistance. Compared to traditional metal parts, plastic parts offer advantages such as good insulation, non-magnetic properties, immunity to signal interference, and resistance to corrosion. Depending on specific requirements, modified engineering plastics can be used to further enhance strength, impact resistance, or temperature resistance.

Commonly used materials include:

1.PC (Polycarbonate): Used for transparent parts, gears, instrument panels, mechanical components, and contour-machined parts.
2.PP (Polypropylene): Suitable for containers, pump bodies, guide rails, and mechanical components with lower strength requirements.
3.PA (Nylon): Applied in gears, bearings, seals, guide rails, and more.
4.PBT (Polybutylene Terephthalate): Utilized for gears, electronic components, textile machine parts, connectors, and guide rails.
5.POM (Polyoxymethylene): Used in gears, spur gears, mechanical connectors, pistons, robotic arms, guide rails, bearings, housings, and more.
Substituting plastic materials for metal parts is a common practice in the mechanical industry to reduce costs.
