There are a variety of manufacturing methods used to create products using plastic polymers, including two shot injection molding, compression thermoset molding and extrusion. While all of these are viable manufacturing processes, there are several advantages to this process that make it the top choice for many plastics manufacturers. The process is relatively simple; one material is injected into a mold in order to make the initial section of the product, followed by a second injection of a secondary material that is compatible with the original material. There are three good reasons many manufacturers use this method of manufacturing plastics or polymers.
The two-step process needs only one machine cycle, rotating the initial mold out of the way and putting the secondary mold around the product so that the second, compatible thermoplastic can be inserted into the second mold. Because the technique uses only one cycle instead of separate machine cycles, it costs less for any production run and requires fewer employees to make the finished product while delivering more items per run. It also ensures a strong bond between the materials without the need for further assembly down the line.
Two shot injection molding enhances the quality of most thermoplastic items in several ways:
Product manufacturers favor two shot injection molding for a wide range of applications, including automotive interior parts, medical devices, tools and toys. It allows manufacturers to combine a variety of materials and colors to create a final product that is both strong and attractive. Some materials that can be effectively combined with this process include silicone and thermoplastics, nylon and thermoplastic elastomers or hard nylon and soft touch materials.
Two shot injection molding could be the answer to your company's product production dilemma. An experienced plastics manufacturer can guide you through the process from concept to finished merchandise and ensure a cost effective solution.
