Injection over molding is a process combining two kinds of materials. Material A is molded onto the substrate, making the outlook of the product smooth and artistic. We are adept at plastic, metal and silicon over molding, such as plastic injection over molding, over molding insert molding and so on.
Two or more kinds of plastic materials and colors;
Case 1: The first injection is hard plastic, the second injection is soft plastic,
Case 2: Two injections are hard plastic
Advantage
Over molding enhances product functionality, aesthetics and ergonomics which providing improved grip, sealing performance and insulation.
Over molding process also allows for the integration of multiple colors and textures and making it highly versatile for applications ranging from medical devices and consumer electronics to automotive components.
Applications:
Daily necessities : such as handle, grip, foot pad, etc., to provide comfortable touch and anti-slip
Electronics products : such as mobile phone protective case, tablet computer protective case, electric toothbrush handle, etc., provide comfortable touch and protection function.
Medical instruments : such as syringe handle, surgical instrument grip, etc., to provide comfortable holding feeling and hygienic performance .
Automobile manufacturing : such as steering wheel, shift lever, etc., to provide good holding sense and comfort.
Outdoor products : such as shoulder straps and handles of backpacks, provide high strength and wear resistance.
Raw material
Commonly used plastic materials for encapsulation, first injection molding materials: PP, ABS, PC, PA, PBT…; second injection molding materials: TPE, TPU, TPR, PC, PBT, ABS, PP….
Semi-automatically produce
Manually put into mold and semi-automatically produce
Fully automatic production：
Mold rotation, double mold and double injection system fully automatic production, the robot arm is placed in the mold for fully automatic production
Processing
Plastic raw material baking→ adding materials into barrel → Melting glue → First shot injection → Second shot injection by rotating mold → Cooling → Ejection→ Taking out the product → 100% measurement → Packing
