What is Overmolding ?
- Overmolding is a manufacturing process in which one material is molded over another to create a single part.
- This process is commonly used to combine the properties of two different materials, such as the strength of plastic with the flexibility of rubber.
- One of the most commonly used, everyday object toothbrushes is being manufactured by overmolding
Overmolding is a powerful and versatile manufacturing process that combines two or more different materials into a single part. Overmolding process is commonly used to create parts with a hard, rigid core and a soft, flexible outer layer.
The overmolding process involves the following steps:
Step:1 – The base component, also known as the substrate, is molded using conventional injection molding techniques. The substrate is typically made of a rigid material such as plastic or metal.
Step:2 – The substrate is cooled and solidified. Then it is carefully prepared for the overmolding process. A release agent may be applied to ensure proper adhesion between the substrate and the overmold material.
Step:3 – The prepared substrate is placed into the overmolding mold. This mold is designed to accommodate the substrate and create the desired shape and features of the overmold.
Step:4 – The overmold material, commonly a rubber or thermoplastic elastomer (TPE), is injected into the mold. The mold cavity is carefully filled, ensuring that the overmold material flows around the substrate and adheres properly.
Step:5 – The mold is then cooled to allow the overmold material to solidify. This helps in forming a strong bond with the substrate. After cooling, the mold is opened. Then, the finished part is ejected.
