TPE Overmolding, Bonding and Substrate Considerations

Design engineers choose TPEs for improved ergonomics, enhanced grip performance, improved aesthetics, and critical impact protection. Applications that benefit from TPE overmolds range from consumer goods to medical insruments to industrial tools and can include knobs, handles, gaskets, seals and grips.

Benefits of Overmolding

With improvements in TPE materials technology, overmolded part designs have become less dependent on mechanical interlocks to hold a TPE in place. Chemical bonds between TPE and rigid materials offer improved part integrity and longevity while eliminating the need for adhesives or surface pre-treatments. System performance can be further optimized by including both chemical and mechanical bonds in the part design. The net benefit is greatly expanded design freedom.

Chemical bonds in Overmolding: 
Improve product function 
Increase margins 
Expand product differentiation 
Enable new design innovation
