Product Description

Preform injection molding machine is a machine specially used to produce plastic preforms. The preform injection molding machine in China is developed with the filling of mineral water, purified water and carbonated beverages. With the expansion of the application range of the preform, higher requirements are put forward for the preform injection molding machine. ZOWEI injection molding machine seized this opportunity and developed a preform injection molding machine specially used to produce plastic preforms.

Preform Injection Molding Machine

What is a preform?

The preform is processed by injection molding, filling the raw materials into the gun mold of the mold at a specific temperature and pressure, and is formed under the working conditions of the injection molding machine. After injection molding, it is a semi-finished product of the intermediate, and then processed into a final product by blow molding.

The related equipment needed are: injection molding machine, mold, production workshop, purification workshop, mixer, grinder, oven.

Related materials are: PVC/PET/PS/PP.

Uses of preforms: preforms are injection-molded products and intermediates. After blow molding, they become end products. The end products include plastic bottles, oil drums, cosmetic boxes, shampoo plastic bottles, spray bottles and other packaging containers. A must-have product for daily life needs.

What is the working principle of the preform injection molding machine?

Seeing that the preform injection molding machine has such a complicated composition, do you think that the working principle of the preform injection molding machine is also very complicated? In fact, the working principle of the injection molding machine is actually very simple. Simply put, it is very similar to the working principle of the syringe used for injection in the hospital. The injection molding machine needs a screw to provide thrust, inject the molten plastic into the closed mold cavity, and then take it out after the mold is solidified and shaped, so that the desired product can be obtained.

Among them, injection molding is a very important link. Injection molding is a cyclical process in the entire work. The main process of each cycle is to first carry out quantitative feeding, then melt and plasticize the added material, and then apply pressure to inject and connect. After the mold is closed and cooled, the mold can be opened to take out the parts. After taking out the plastic part, the mold is closed again for the next cycle.
