The technique of overmolding consists of performing a molding on a product.
In plasturgy, the overmolding technique consists of injecting plastic onto an insert (made of metal, plastic, ceramic,etc.).
The purpose of the overmolding can be, for example:
- to protect the overmolded insert (electrical protection, protection against impacts, etc.)
- to mix two plastic materials in order to obtain: two colours, a hard part and a soft part, etc.
- overmolding by insertion of an insert in a mold
- overmolding by two-material injection (injection of the plastic insert and overmolding in one and the same mold)
