A: The insert molding process begins with the creation of a metal insert. This can be done through machining, die casting, or other processes depending on the product’s specifications. The insert is then placed into the injection mold tool before it is closed and secured. Molten plastic is then injected into the mold around the metal part until it cools and solidifies. Once the plastic cools, it is removed from the mold and any necessary finishing is performed before it’s ready to use in product assemblies.
