Service Performance of Mould

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

2. High specific strength and specific stiffness: the absolute strength of plastic is not as high as 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 a variety of high-strength fibrous, flaky and powdered metal or non-metal as fillers have higher specific strength and stiffness than metal.

3. Good chemical stability: the vast majority of plastics have good acid, alkali, salt, water and gas resistance, under general conditions, they do not chemically react with these substances.

4. Electrical insulation, heat insulation, sound performance is good.

5. Good wear resistance and self-lubrication: the friction coefficient of plastic is small, good wear resistance, has a good self-lubrication, plus the specific strength is high, the transmission noise is small, it can work effectively in liquid medium, semi-dry or even 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.

6. Strong bonding ability.

7. Good forming and coloring performance.
