Below is a list of Rapid Injection Molding manufacturers from Middlesex, New Jersey. Rapid injection molding, also referred to as short-run injection molding, is primarily used in prototyping and the low-volume production of plastic parts since the production time is drastically shorter than conventional molding process. A major advantage of rapid injection molding is that it allows the manufacturer to bridge the gap between the concept or design and the full production by providing them with a quick, low-volume order that allows them to show working models of the parts as soon as possible, which is typically 3-15 days.
