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.

Continue ReadingUndercuts achieve complex plastic part designs for the injection molding process. For example, overmolding and insert molding.
An undercut is any indentation or protrusion that prohibits part ejection from a mold. It is a feature that the cavity and core cannot capture alone. It is die-locked which prevents the part from being ejected from the cavity.
Continue ReadingOvermolding is a two-shot injection molding process that creates a single part by combining two separate but complimentary thermoplastic materials. The first shot, called …
Continue ReadingMaterials for medical and the healthcare industry must meet more stringent criteria than perhaps other industries as there are regulations that mesh with required performance criteria for various healthcare applications. This document provides insight to regulations, known material performance criteria, and related medical/healthcare considerations that should be considered when applying materials to an injection molding process for part production.
Continue ReadingHigh 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.
