There was once was a time when building parts for vehicles, machines, building materials, and mechanical parts was time-consuming and very labor intensive. This was especially true when the parts or components being manufactured were very small., but that was changed with the creation of injection molding. The process literally created a more advanced and economical way to produce parts.
Everything from toys to engine parts can be created through the process of injecting molten material into a mold, and the process can be done using a variety of materials. Metals are just one of the many materials used, but polymers, thermoplastics, glasses, and even confections can be used as materials in the molding process.
Once a part has been designed, a metal mold is created and a molding injection machine is later used to inject the molten material or materials into the mold. The process can be used to create parts on a large scale for the mass production of cars, toys, household appliances and thousands of other products.
