Precision plastic molds have good wear resistance and self-lubrication: plastics have small friction coefficient, good wear resistance, good self-lubrication, high specific strength and low transmission noise. Works effectively in dry or even dry rubbing conditions.

1. Low density: The low density of plastic is of great significance for reducing the weight of mechanical equipment and saving energy, especially for vehicles, ships, aircraft, and spacecraft.

2. High specific strength and specific stiffness: the absolute strength of plastic is not as high as that of metal but the density of plastic is small, so the specific strength (σb/ρ) and specific stiffness (E/ρ) are quite high. In particular, reinforced plastics made of various high-strength fibrous, flake and powdered metals or non-metals as fillers have higher specific strength and specific stiffness than metals.

3. Good chemical stability of precision plastic molds: Most plastics have good resistance to acid, alkali and salt, water and gas, and they do not chemically react with these substances under normal conditions.

4. Good electrical insulation, heat insulation and sound insulation performance.

5. Good wear resistance and self-lubrication: plastic has small friction coefficient, good wear resistance, good self-lubrication, plus high specific strength and low transmission noise, it can be used in liquid media, semi-dry or even Works effectively under dry friction conditions. It can be made into machine parts such as bearings, gears, cams and pulleys, and is very suitable for occasions where the speed is not high and the load is not large.
