Mold Performance

1. Low density: Plastic has a low density, which is of great significance for reducing the weight of mechanical equipment and energy conservation, especially for vehicles, ships, aircraft, and spacecraft.
2. Higher specific strength and 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（ σ B/ ρ)、 Specific stiffness (E/ ρ) Quite high. Especially reinforced plastics made with various high-strength fibrous, sheetlike, and powdered metal or non-metal fillers have higher specific strength and stiffness than metals.
3. Good chemical stability: The vast majority of plastics have good resistance to acids, alkalis, salts, water, and gases. Under normal conditions, they do not undergo chemical reactions with these substances.
4. Good electrical insulation, thermal insulation, and sound insulation performance.
5. Good wear resistance and self-lubrication: Plastic has low friction coefficient, good wear resistance, good self-lubrication, high specific strength, and low transmission noise. It can effectively work in liquid media, 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 situations with low rotational speeds and low loads.
6. Strong bonding ability.
7. Good molding and coloring performance.
