Technical Features of Plastic Injection Molding
Plastic injection molding is a manufacturing process for producing plastic parts by injecting molten plastic into a mold cavity. The process is suitable for producing high-volume parts in a short period of time. Below is a comparison of the key technical features involved in plastic injection molding:
| Feature | Description |
|---|---|
| Plasticization | Feeding plastic material in the form of pellets into a heating chamber to melt. |
| Injection | Melting plastic inside the barrel and injecting it into the mold at high pressure. |
| Packing | Keeping the mold closed under high pressure to avoid internal stresses. |
| Cooling | Allowing the molten plastic to cool and solidify inside the mold. |
| Ejection | Opening the mold and ejecting the finished plastic part. |
Types of Plastic Injection Molding
There are several types of plastic injection molding processes, each suited for different applications and materials. Below is a comparison of the various types:
| Type | Description |
|---|---|
