Insert molding is an injection molding process that involves adding inserts, particularly metal, into an injection-molded part. Placing the insert within the mold cavity occurs before molten plastic injection. Consequently, on cooling, the insert becomes a permanent plastic part.
Insert molding facilitates the manufacturing of strong, durable, and lightweight parts, which is why several industries are adopting this process. Besides, the metal inserts strengthen the mechanical properties of plastics or thermoplastics used during the insert molding process.
