Insert molding is the process of injection molding molten thermosplastic around ceramic or metal pieces placed in the injection molding cavity.
These inserts can be threads or other attachment points enabling two or more custom parts to be assembled together reducing the need for secodary manufacturing and/or installation processes.
Insert molding plastic parts is an effective and cost-efficient solution for reducing a products overall cost, by incorporating parts into the molding process which would otherwise require secondary assembly or installation.
Insert molding creates a strong bond between integral pieces of your final product. Inserts are offered in a wide variety of materials including plastic, metals, ceramic or any other material that can withstand the pressures and temperatures of the injection molding process.
Accurate mold design and construction is essential to insert molding, not only to maintain part tolerances but also assure the tooling reliability.
