Over Molding

Over molding of keyplast is a special plastic molding process. Overmolding injection molding is similar to the two-color molding or two-shot molding process. Over moulding can make the surface of the product full of softness and increase product functionality and added value. 

With this technology, product functions can be increased, such as noise reduction, vibration reduction, waterproof, anti-collision and added value. Overmolds is widely used in mobile phone protective shells/mobile phone protective sleeves.

Regarding this problem, we can learn one or two of the advantages of overmolding injection molding.

First, the product quality of over-molding can be improved. Injection overmolding can optimize the copolymerization of hard and soft materials to form strong molecular bonds. The result is a single part with production and feature advantages. It can be used for various product designs in injection moulding applications. The injection overmolding also allows the use of transparent plastics, colorful graphics, and fashionable finishes for molding, thereby improving your product functionality and market value.

Second, plastic injection overmolding can reduce the cost of production. Complete the entire production process in one injection molding machine, overmolding injection molding effectively reduces unit costs, reduces processing and secondary assembly, and reduces costs and waste associated with assembly defects, thereby shortening the molding cycle and improving work efficiency.

Furthermore, China plastic injection mold factory can also improve people's experience. Over the past 10 years, it has completely changed the aesthetic standards, design ideas, and functional requirements of consumer products. The use of plastic materials with different textures has improved the touch and function of products. Many of the common toothbrushes and mobile phone protective cases in our lives are products produced by using injection overmolding technology.
