Plastic resin pellets are loaded into the hopper, where it travels into the barrel of the injection molding machine. Through both heat and pressure, the plastic pellets are melted into a molten material that is ready to be injected. As the screw turns it creates pressure which will help push the molten plastic through the nozzle and into the mold.

Before we jump into the injection molding pitfalls you should avoid, here’s a quick review of the Injection Molding Process, Injection Molding Basics, and Rapid Injection Molding.
High quality, efficient tooling relies heavily on good part design as well as advanced skills in mold design and the manufacturing of the tool. An injection mold is a highly precision tool that must be rugged enough to withstand hundreds of thousands of high pressure molding cycles.
The result is an extremely efficient process resulting in delivery of injection molded components in less than fifteen (15) business days on average at a very
