How to Identify the Plastic material?

Plastic material identification Judging thermoplastics and thermosets: All thermosets have no softening process when heated or burned, only become brittle and coked; All thermoplastics, which are heated or burned, undergo a soft melting process, but different plastics burn. The phenomenon…

Gas-assisted injection molding

Gas-assisted injection molding is an innovative technology developed on traditional injection molding. GIM (Gas-assisted injection molding) was adopted in production in the 1980s. The gas-assisted injection molding system directly injects inert gas (usually nitrogen) into the melted plastic in the…

Hot runner system for injection mold

A plastic mold hot runner system is a system used in the injection molding of plastics. The system injects molten plastic into the mold cavity through a heated runner system. This system is used to produce molded parts with intricate…

PMMA injection molding

Acrylic is also called polymethyl methacrylate (PMMA). Due to the defects , such as low surface hardness, easy scratching, low impact resistance and poor molding fluidity, the modification of PMMA appears alot. Such as copolymerization of methyl methacrylate with styrene…

cool of plastic mold

The plastic mold can be viewed as an exchanger that carries the heat of the hot melt away from the plastic mold by the circulating refrigerant. The cooling system plays an important role More than two-thirds of the thermoplastic injection…
