Overmolding for Wearable Device Enclosures
The rigid shell and the soft grip shipped as one enclosure, after gate placement and the material pair were reviewed.
Challenge
What needed to be solved
The enclosure needed a rigid body and a soft grip in one part, without the grip pulling away or sinking the cosmetic face. Soft-layer choices such as TPE are in the materials library.
Solution
How the program was approached
Overmolding put the soft layer on the rigid shell. Gate placement and the material pair were reviewed so the grip could bond.
Outcome
What the result looked like
The enclosure shipped with the grip molded on, so a separate grip assembly step was not required.
