## What is Injection Molding?
Injection molding is a manufacturing process for producing parts by injecting molten material into a mold. It is most commonly used for thermoplastic and thermosetting polymers, with a wide variety of other materials such as metals, glasses, elastomers, and confections also being used.
### The Process Steps:
1. **Clamping**: The two halves of the mold are clamped together by the molding machine.
2. **Injection**: Plastic pellets are melted and injected into the mold cavity under high pressure.
3. **Cooling**: The molten plastic cools and solidifies within the mold.
4. **Ejection**: The mold opens, and the solidified part is ejected.
### Common Applications:
* Automotive components (dashboard parts, interior trim)
* Medical devices (syringes, surgical instruments)
* Consumer electronics (phone cases, remote controls)
* Packaging (bottle caps, containers)
Injection molding offers high precision, repeatability, and cost-effectiveness for mass production.
