Overmolded Elastomers

We excel at creating “soft-touch” interfaces by molding a flexible elastomer (TPE/TPU) over a rigid substrate (like Nylon, PC, or ABS). We ensure the “feel” and durometer of the material are optimized for your end-user, while guaranteeing that the mechanical bond between the substrate and the overmold is durable enough to survive years of use without peeling.

When ergonomics, impact resistance, or environmental sealing are paramount, our elastomer overmolding process delivers. This technique involves molding a flexible thermoplastic elastomer (TPE) or polyurethane (TPU) directly over a rigid, pre-molded plastic substrate.

We engineer the substrate and the overmold for optimal mechanical and chemical adhesion. Whether it is a Polycarbonate (PC) housing requiring a TPU grip or a complex ABS assembly needing an integrated TPE gasket, we manage the precise melt temperatures and injection pressures required to prevent substrate deformation while ensuring a flawless, peel-resistant bond.
