What are the Basics of Plastic Injection Molding Process?

What is Injection molding？

TEAM MFG Injection molding is a manufacturing process used for the mass production of identical plastic parts. It’s a method of plastic injection where molten plastic is inserted into a mold to produce a part in the shape of the mold cavity, creating a physical representation of modeled plastic parts.

What is plastic injection molding process?

Our basic process for plastic injection molding includes important design considerations to help improve part moldability, enhance cosmetic appearance, and reduce overall production time.
The plastic injection molding process produces custom prototypes and end-use production parts with standard lead times as fast as 7 days. We use aluminum molds that offer cost-efficient tooling and accelerated manufacturing cycles, and stock about 200 different thermoplastic resins.

What are the most common types of injection molding processes?

Injection molding manufactures high quantities of parts, faster than other manufacturing methods (machining or 3D-printing).
•    Thermoset injection molding
•    Overmolding
•    Gas-assisted injection molding
•    Co-injection & Bi-injection molding
•    Microcellular injection molding
•    Powder injection molding (PIM)

Common applications for plastic injection molding:

•    low-volume production
•    bridge tooling
•    pilot runs
•    functional testing and prototyping
