Over molding has developed into a rather standard process in the field of injection molding. We all enjoy the lightweight, durability, look and feel of modern plastics. Over molding is basically the process of injection molding two different plastics, one on top of or around the other. This results in a single structure that is strong and rigid on the inside yet flexible, colorful and easy to hold on the outside.
The variety of textures also makes over molded products more comfortable and easy to use, ultimately providing more personalized products. This process helps to contribute to safety by making components shock absorbent and covers potentially harmful corners and edges.
The best way to produce over-molded plastic components is with a vertical/vertical injection molding machine. It relies on the gentle force of gravity to clamp the inner and outer parts together.
