Custom plastic over-molding can strengthen, protect and improve a part or end product.
Over-molding continues to be an attractive option because of the functional flexibility it affords product designers and engineers. Using two separate plastic injection molds on the plastic injection molding press, two materials are bonded together during the plastic over-molding process to form plastic parts and components with unique visual or ergonomic appeal, such as handles or knobs. Custom plastic overmolding is also used to strengthen, protect and improve a part or end product, while reducing cost, labor and materials.
Plastic overmolding offers numerous advantages, including:
Reduced secondary operation, assembly and labor costs (molded as one assembly)
Eliminates bonding step in the manufacturing process (improved component reliability)
Plastic overmolded components ensure proper alignment and prevents loosening
Plastic resin can provide improved resistance to vibration and shock
Improved part strength and structure
Enhanced design flexibility and multi-material components
