Overmolding and Bonding

Soucy Baron has strong expertise in overmolding and bonding techniques. Overmolding consists of coating a metal or plastic insert with an elastomer, while bonding is used to combine the mechanical strength of a rigid structure (metal or plastic insert) with the flexible characteristics of rubber. To do this, the insert is first sanded and coated with adhesive that is sprayed manually or automatically on the surface to be in contact with the elastomer. This bonding creates much more efficient systems than simple assembly.

The bonding reaction occurs during overmolding, which can be done by compression, injection or transfer. The overmolding reduces costs by eliminating the extra steps of assembly and finishing. In addition, this method improves the part's watertightness and damping properties, while respecting the target physical and mechanical properties depending on the part application.
