The principle of injection molding is to heat the plastic raw material to a molten state, then use the injection system to inject it into the mold, and then cool and solidify it to form the desired product. The specific process is as follows:
Raw material preparation: Select the appropriate plastic raw material and dry it through a dryer to ensure that the dryness of the raw material meets the requirements.
Heating and melting: Put the dried plastic particles into the barrel of the injection molding machine and heat them to a molten state through a heating device.
Injection molding: Under the action of the injection system, the molten plastic is injected into the mold at high pressure and a certain injection speed is maintained.
Cooling and solidification: In the mold, the molten plastic is cooled through the cooling channel to quickly solidify and form.
Open the mold and take out the parts: After cooling, open the mold and take out the molded plastic products.
Post-processing: According to needs, the molded products are post-processed, such as trimming, spraying, printing, etc., to improve the appearance and performance of the products.
