How is the Process of Overmolding Typically Accomplished?
Typically the substrate material or part is placed into an injection molding tool at which point the overmold material is shot into, onto, or around the substrate. When the overmold material cures or solidifies, the two materials become joined together as a single part.
Free Tip: It is usually a good idea to have your substrate and overmold material interlock in some mechanical capacity. This way, the two materials will not only be bonded together chemically, they will also be held together physically.
