If I had an accident or a medical emergency, there would be no one there to help me. Multi-cavity co-injection molding offers a great deal of flexibility in terms of part development. Nature of Duties: Operate hoist to set and remove tooling from injection molding machines Set up molding machines and equipment to predetermined specifications to produce needed parts. Injection molding relies on pumping molten plastic into a cavity that is the exact shape of the part you want (actually, the cavity is a little larger to allow for plastic shrinkage as it cools). Process Plastic: Injection Molding In its broadest terms, thermoplastic injection molding forms a part by forcing (injecting) a liquid resin (either as a hot, molten thermoplastic, or a thermo set that is still in liquid form) into a closed mold, under pressure, until the part has cooled or cured and can be ejected from the mold. In comparison to regular injection molding, the cavity of the molding tool is not closed completely at the beginning of the process.
