Injection Molding Process
What is injection Molding
Injection molding is the process of obtaining moulded products via injecting heat-molten plastics into a mould. Then cooling parts down and solidifying them in the cavity. The way is applied for the high volume of products with complex forms and is largely involved in the field of plastic industry. The injection moulding method consists of 6 main steps as follows. The method is carried out as described above and the products are carried out in succession by repetition of the run.
How does injection molding work?
The injection molding process consists of six steps: 1. Clamping 2. Injection 3. Dwelling 4. Cooling 5. Opening 6. Ejection. Each stage is indispensable and needed to be set with the right parameter.
A molding machine has three basic components: the mold, the tightening unit, and the injection unit. The high-resistance clamp works by keeping both halves of the injection mold together during injection and cooling. Tightening is carried out with the help of hydraulic or electrical pressure.
