Injection Molding Processes

The same plastic injection molding process that is used to produce large quantities of parts can be used to develop a single prototype. There are four main stages involved in manufacturing parts using injection molding. The first part of the process converts the polymer that will be used--whether it is vinyl, ABS, or urethane--to a liquid form from its solid state at room temperature. The material is then poured into a cast, where it takes on the shape of the final product. The cast is then chilled so that the liquid polymer returns to its solid state. Finally, the hardened plastic is removed from the cast.

Machinery for the Plastic Injection Molding Process

Efficiency is gained by producing large runs of a single product. It is common to produce hundreds of thousands of parts in one run. You need develop the cast that will be used for plastic injection molding just once for each piece of machinery on which it will be used simultaneously. The process of producing parts is then automated for the most part. While this benefits companies producing individual parts in bulk, it may not as efficient when you are developing a prototype.

At Morgan Industries, Inc., you will find a selection of press machines that can be used to produce parts in any quantity that your business may need, from prototypes to larger runs.
