Overmoulding & Insert Moulding Design

Multi-material parts with strong, reliable bonds.

Plastic Part & Assembly Design

Overmoulding and insert moulding combine soft-touch grips, seals, metal inserts and multiple colours into one part. We design the geometry, material pairs and mechanical interlocks that make bonds reliable and tooling practical.

What’s included

Material compatibility and bond selection
Mechanical interlock design
Shut-off and sealing surface design
Insert placement and retention
Two-shot and pick-and-place process planning
Tooling concept review
