Plastic molding is a processing method commonly used by plastic barrel manufacturers. Products formed by plastics have the advantages of light weight, good strength, corrosion resistance, good insulation performance, bright color, beautiful appearance, etc .; the molding equipment is easy to operate, high productivity, and the production process is easy to realize mechanization, automatic plastics can add 200 liters barrel

Plastic molding is a processing method commonly used by plastic barrel manufacturers. Products molded from plastic have the advantages of light weight, good strength, corrosion resistance, good insulation performance, bright color, beautiful appearance, etc .; molding equipment is easy to operate, high productivity, production process is easy to achieve mechanization, automatic plastic can be processed into any shape The cost of the products is lower under mass production conditions. Due to the excellent technical and economic characteristics of plastic barrel manufacturers, plastic molding plays an important role in the production of plastic products and even the plastic industry. There are many types of plastic molding, including various molding, lamination and calendering.

Among them, there are many types of molding, and commonly used molding processing methods such as injection molding, compression molding, transfer molding, extrusion molding, pneumatic molding, etc., account for more than 90% of the processing of all plastic products. Their common feature is the use of molds to form plastic products with a certain shape and size (referred to as plastic parts or products). The mold for molding plastic products is called a plastic molding mold.

Injection molding is based on the principle of metal die casting molding. The basic principle is to use the squeezability and moldability of plastics to first send loose granular or powdery molding materials from the hopper of the injection machine to the high-temperature barrel for heating 、 Melting and plasticizing to make it into a viscous melt, then under the high pressure of the plunger or screw, it is injected at a high flow rate through the nozzle at the front of the barrel into a closed mold with a lower temperature, and is cooled and shaped After that, the shape and size given by the mold cavity can be maintained. The mold opening and closing mechanism opens the mold, and the injection molded plastic parts can be taken out under the action of the pushing mechanism. The principle of injection molding and its corresponding production process.
