Insert Molding is done when a metal, plastic or ceramic part is embedded in plastic to improve product structure. It is a widely used process and one that we at ACT specialize 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 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. Tooling costs also lowers significantly as we can use conventional single shot injection machines for Insert Molding instead of multi-shot processing.
