Molding plastic over plastic, or molding plastic over a preformed part such as a metal insert or delicate electronic requires a combination of specialized machinery and a highly skilled operator; but get the mix right, and the benefits are noteworthy.
Commonly referred to as either multi-shot or multi-component molding, this advanced version of injection molding is a collective term that refers to an injection molding process where two or more materials are molded in the same molding machine and within the same molding process.
Multi-shot molding is performed on one machine that is programmed to perform two injections in one cycle, this double dose cycle injects plastic into a mold initially, then rotates and a different type of plastic is injected into the mold from a second nozzle to form the end part.
Multi-component on the other hand, also known as over molding, follows a similar machine process, yet encompasses a non-plastic part to sandwich it.
Both of these formats of plastic manipulation play a critical part in the automotive industry and both, as specialized as they are, are commonplace within the impressive line-up at leading European supplier NS KUNSTSTOFFTECHNIK - CZ
Offering a host of benefits including lower production costs due to the use of a single machine rather than multiple (which in turn eliminates many secondary processes), reduced production time, improved quality and of course, reduced assembly costs and time given it is made all in one process, it is easy to see why multi-shot is so popular.
