>Material properties: corrosion resistance, excellent electrical insulation (especially high-frequency insulation), can be chlorinated, irradiated, modified, and can be reinforced with glass fiber to melt the melting point, rigidity, hardness and strength of polyethylene High pressure, low water absorption, good electrical properties and radiation resistance. High pressure polyethylene has good flexibility, elongation, impact strength and permeability. Ultra-high molecular weight polyethylene has high impact strength, fatigue resistance and wear resistance. Low pressure polyethylene has good flexibility, elongation, impact strength and permeability. Ethylene is suitable for making corrosion-resistant parts and insulating parts. High-voltage polyethylene is suitable for making films and other ultra-high molecular weight polyethylene. It is suitable for making shock-absorbing, wear-resistant and transmission parts. It has low moisture absorption, does not need to be fully dried, and has extremely fluidity. Good fluidity is sensitive to pressure. When molding, it is better to use high-pressure injection. The material temperature is uniform, the filling speed is fast, and the pressure is sufficient to maintain. It is better to use a direct gate to prevent uneven shrinkage and increase in internal stress. Select the gate location carefully to prevent shrinkage cavities and The deformation shrinkage range and shrinkage value are large, and the directionality is obvious. It is easy to deform and warp but the speed should be slow. The mold should be equipped with a cold material cavity and a cooling system. The heating time should not be too long, otherwise it will decompose and burn the plastic parts
When there are shallow side grooves, forced demoulding is possible
Melt rupture may occur, and it is not suitable to come into contact with organic solvents to prevent cracking
