Our original overmolding planning process reviews how a second material can be formed over a prepared substrate or insert to create grips, seals, housings, and other integrated interfaces.
Assess bond strategy, geometry, material pairing, tool access, and the completed part’s use conditions before the manufacturing route is selected.
An original guide for planning material interfaces, bond strategy, tool access, and compatible material choices.
