The plastic is first heated and melted in the barrel of the injection machine, then pushed by the screw or plunger of the injection machine, the plastic enters the mould cavity through the injection nozzle and the pouring system of the mould, the plastic is cooled and hardened, and the product is released from the mould. The structure usually consists of moulding parts, pouring system, guiding parts, pushing mechanism, temperature regulation system, exhaust system, support parts and other parts. The materials used for manufacturing plastic moulding steel modules are usually carbon structural steel, carbon tool steel, alloy tool steel, high speed steel, etc. The injection moulding process is usually only applicable to the production of thermoplastic products. The plastic products produced by the injection moulding process are very extensive, from daily necessities to all kinds of complex machinery, electrical appliances, transport parts, etc. are all moulded by injection moulding, which is one of the most widely used processing methods in the production of plastic products.
