The plastics injection process is a complex mix of many parameters such as Material, Temperature, Injection Location, Injection Time, Pressure, Packing Time. Introducing a new series of plastic injection molding basics articles developed to give our readers a better understanding of plastic injection molding manufacturing including information on the presses, processes and pitfalls in our industry.
