The Plastic Injection Molding Process
1.Mold Design
A detailed mold design is created based on the specifications of the part to be manufactured.
2. Mold Fabrication:
The mold is fabricated using high-quality materials and precision CNC machining techniques.
3. Material Preparation
Plastic resin pellets are melted down and injected into the mold cavity under high pressure.
4.Injection
The molten plastic is injected into the mold cavity, filling it completely and taking the shape of the desired part.
5. Cooling
The mold is cooled to solidify the plastic and allow it to take its final form.
7. Finishing
Any additional finishing processes, such as trimming or surface treatment, may be applied to the part as needed.
6. Ejection
Once the plastic has cooled and solidified, the mold opens and the part is ejected from the mold cavity.
8. Inspection
The finished parts undergo rigorous inspection to ensure they meet quality standards and specifications.
