Insert Molding Technology
When a metal. plastic or ceramic parts needs to be embedded in plastic to improve product structure it's calling Insert Molding. It's a widely used process and one that POWSTAR specialized in.
With Insert Molding, a part is placed in a mold cavity then a selected plastic material is injected directly over it resulting is a single part with the insert(s) encapsulated by the material. This process normally uses engineering plastics for improved wear resistance. tensile strength and weight reduction.
Insert Molding can be a highly efficient alternative to the assembly of discrete parts using soldering connectors, fasteners or adhesives. It also expands plastic capabilities and can reduce final product cost by limiting the amount of costly metal needed to create a part. And importantly, because we can use conventional single shot injection machines for insert molding, tooling costs are lower than with a multi-shot processing.
