How Plastic Injection Moulding Works
Direct Answer
Plastic injection moulding involves melting plastic resin, injecting it into a precision mould, cooling the material until it solidifies, ejecting the finished component, and performing quality inspection before packaging.
Step 1: Material Preparation
Plastic granules are selected according to product requirements.
Common materials include:
- ABS
- Polypropylene (PP)
- Polycarbonate (PC)
- Nylon
- HDPE
- PVC
The raw material is dried to remove moisture before processing.
Step 2: Injection Moulding Process
The plastic pellets are heated until molten and injected into a steel mould under controlled pressure.
The mould is cooled until the plastic solidifies.
The finished component is then ejected automatically.
Modern machines use computer-controlled systems to ensure high precision and repeatability.
Step 3: Quality Inspection and Packaging
Finished products undergo:
- Dimensional inspection
- Surface finish evaluation
- Functional testing
- Color consistency checks
- Assembly verification
- Packaging inspection
Only approved products proceed to dispatch.
