The four stages of injection molding are clamping, injection, cooling, and ejection.
Here's a breakdown of each stage:
- Clamping: Before the plastic material is injected, the two halves of the mold must be securely closed. This process is called clamping.
- Injection: Plastic pellets are fed into the injection molding machine via a hopper. The plastic is then melted and injected into the mold.
- Cooling: The molten plastic needs to cool and solidify inside the mold to take the shape of the desired part.
- Ejection: Once the plastic has cooled and solidified, the mold opens, and the finished part is ejected.
