Take you to understand the performance of the mold;


1. Small density: the density of plastic is small, which 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 relative strength of plastic is not as high as metal, but the density of plastic is small, so the specific strength (σb/ρ), specific stiffness (E/ρ) is quite high. In particular, with a variety of high degree of fiber, flake and powder metal or non-metal filler made of reinforced plastic, its specific strength and specific stiffness is higher than metal.


3. Good: The vast majority of plastics have good resistance to acid, alkali, salt, water and gas, under normal conditions, they do not react with these substances.


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


5 wear-resistant and self-lubrication: plastic friction coefficient is small, good wear resistance, has a good self-lubrication, plus high specific strength, transmission noise is small, it can work in liquid medium, half dry and even dry friction conditions. It can be made into bearings, gears, cams and pulleys and other machine parts, very suitable for low speed, small load occasions.


6. Strong bonding ability.


7. Good molding and coloring performance.
