HongTu Mold has many experiences 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 over-molding process to form plastic parts and components with unique visual or ergonomic appeal,Plastic over molding 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 , Automotive products and components!
A wide range of thermoplastic materials can be over-molded, including soft plastics such as urethanes and thermoplastic elastomers (TPE), and hard plastics such as nylon and Polycarbonate Custom plastic over-molding is also used to strengthen, protect and improve a part or end product, while reducing cost, labor and materials
Advantages
- Reduced secondary operation, assembly and labor costs, molded as one assembly
- Eliminates bonding step in the manufacturing process
- Improved component reliability, plastic over-molded 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 over-molding allows for production of parts molded of multiple thermoplastic materials
Applications
Custom over-molded plastics provide competitive advantages in a wide range of applications, including:
- Medical devices and instruments
- Part with soft grip handles
- Knobs for appliances, controls and assemblies
- Encapsulated electronic devices and electrical components
- Window reveal moldings
Proper mold design and construction and material selection are important in custom plastic over-molding to maintain part tolerances and tooling reliability. Whether re-engineering existing products or developing new products, carefully engineered custom over-molded plastic parts and components can eliminate the need for a variety of secondary operations such as sonic welding, bonding, gasketing and assembly saving time and money!
From concept to delivery, learn more about how Hongtu Mold provides competitive advantage with custom over-molded plastics through early supplier involvement in the engineering and design process, design for manufacturability, project management.
