Insert Molding / Overmolding

Ming-Li Plastics is a custom insert molder with expertise in custom insert molding and custom insert molded plastics

MING-LI is a ISO/IATF 16949 approved insert molding company with core competence only severing consistent uncompromising quality insert molding product to our customer. We has many years of experience as a custom plastic insert molder.

Plastic injection insert molding is a plastic injection molding process in which thermoplastic material is molded around an insert piece or pieces placed in the plastic injection molding cavity, resulting in a single strongly bonded, integrated assembly, with the insert or inserts encapsulated by the plastic. Inserts can be metal, another plastic, ceramic or just about any substance that can withstand the plastic injection molding process.

Some of the first insert molding applications were for placing threaded inserts into molded parts and encapsulating wire plug connections on electrical cords.
Current custom insert molding applications are wide ranging with few limitations on material combinations, including :
  • Reduced assembly and labor costsUmspritzen
  • Reduced size and weight
  • Improved component reliability
  • Improved part strength and structure
  • Enhanced design flexibility
  • Consolidation of components
