Molded-In Inserts for Plastics
Molded-In Inserts are placed over core pins by an operator or a pick-and-place robot prior to the closure of the mold cavity during the plastic injection process. Molded-In Inserts offer exceptional torque and pull-out resistance due to unrestricted plastic flow around the insert body, and are often the insert of choice for thermosets and engineered plastics with a high percentage of filler. The minor thread diameter tolerance is controlled to ensure positive positioning and perpendicularity of the insert on the core pin during the molding process. SPIROL's molded-in inserts are made from 2024 aluminum, a light-weight, lead-free grade.
