EVCO Plastics is a leader in custom plastic overmolding - a plastic injection molding process in which one thermoplastic material is molded over another material to form one part.
Using two separate plastic injection molds on the plastic injection molding press, two materials are bonded together during the plastic overmolding process to form plastic parts and components with unique visual or ergonomic appeal, such as handles or knobs.
Plastic overmolding technology is employed for a wide range of aesthetic and functional purposes in many industries and applications, such as Medical Devices, Appliances, Electronics, Consumer, Agricultural and Automotive products and components.
A wide range of thermoplastic materials can be overmolded, including soft plastics such as urethanes and thermoplastic elastomers (TPE), and hard plastics such as nylon and polycarbonate.
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, prevents loosening and the plastic resin can provide improved resistance to vibration and shock
Improved part strength and structure
Enhanced design flexibility and multi-material components
Custom plastic overmolding allows for production of parts molded of multiple thermoplastic materials
