Molded-In Inserts

SI (Standard Inserts) Molded-In Inserts are installed during the molding process, and the inserts are located in the mold cavity by core pins. The core pins are withdrawn when the mold is opened, leaving the inserts permanently encapsulated in the plastic section with only the threads exposed. Inserts installed during the molding process avoid the need for additional procedures or installation equipment. The molded-in inserts include blind threaded inserts (IBA/IBB/IBC), self-locking blind threaded inserts (ILBC), through threaded inserts ( ITA/ITB/ITC), and knurled inserts (STKA/STKB/STKC). Typical applications include electronics (wearables, smartphones, and hand-held devices), automotive, aerospace and defense, medical, transportation, industrial, and recreational equipment.
