Two-Stage Injection Molding: Overmolding PC and TPE

Two-shot sequential overmolding

Introduction to Over Molding and Two Shot Sequential Molding

Mechanical Engineering Part of the Day: Insert molding and overmolding combined in one component. Hybrid molding processes allow metal inserts to be encapsulated within structural plastic while a secondary material is overmolded for grip, sealing, or vibration control. Mechanical engineering design must manage bonding interfaces, thermal expansion differences, and manufacturing sequencing to ensure structural integrity and long-term reliability. 🙌🏼⚙️ #mechanicalengineering #insertmolding #over
