Insert Molding allows us to mold plastic over, around or through a pre-molded or preexisting component. These components can be metal or plastic of the same different than material a the over-molded area. Utilizing insert molding can reduce final product cost by limiting the amount of metal needed to create a part. This molding technique allows for the assembly of discrete parts and often eliminates the need for soldering, fasteners, connectors, or adhesives.

Overmolding involves plastic injection molding of one material over a second material. This process requires extensive knowledge of material properties and molding processes to ensure that the two components create either a chemical or mechanical bond, depending on the goal of your product. Overmolding can allow for flexible materials and rigid materials to combine into one finished part eliminating the need for adhesives or additional assembly steps to completion.
