Injection Molding

Plastic Injection Molding

Viking Plastics uses plastic injection molding to create a wide range of components and products, from quick connects and shipping caps to battery cases, commercial appliance parts, and caps and closures. Our processes are designed for high volume — thousands or even millions of units — and consistent quality.


The Process

Raw plastic (in pellet or granule form) is heated and mixed in the barrel of a molding machine until it is soft enough to be injected into the mold with a ram- or screw-style plunger. The mold, often designed by our engineers and made of steel or aluminum by a toolmaker, can have a single cavity or multiple cavities to produce several of the same unit per shot. When the plastic has cooled and hardened to the configuration of the cavity, the part is ejected from the mold, and the process is repeated.


There are a wide variety of applications for parts produced with plastic injection molding:
