Basics and Benefits of Custom Plastic Injection Molding:
Injection molding is a manufacturing technique where plastic pellets are melted down and injected into a mold to form specific shapes. It’s a highly efficient process, allowing for rapid production of large quantities of identical parts with impressive accuracy.
Steps involved in injection molding:
- Material Melting: Plastic pellets are heated until they become molten.
- Injection: Molten plastic is injected into a mold cavity to take its shape.
- Cooling: The plastic solidifies as it cools within the mold.
- Ejection: Once solidified, the part is ejected from the mold for further processing.
