Two-shot in-mold integration of magnet and structural resin
Sequential or insert two-shot molding that joins a plastic-magnet shot to a structural resin or insert (shaft, gear, cover) inside the tool, removing a later adhesive assembly step.

Problem solved
Bonding a magnet to a cover, shaft or gear adds assembly labor, adhesive-strength inspection and positional scatter. Two-shot / insert molding is used when the buyer wants the magnet and neighboring structure as one molded unit with tool-controlled alignment.
Application contexts
- Magnet-plus-housing units that currently use adhesive
- Small motors needing shaft- or gear-integrated bonded magnets
- Sensor magnets that must stay centered to a molded datum
Technical principle
A first shot of magnetic compound and a second shot of a compatible structural resin (or an insert metal) are formed in one mold. The company states the joint is mechanical/welded rather than adhesive, and that undercut geometry can be used when the two resins do not weld. It also flags thermal-expansion mismatch and two-shot tool cost as conditions that must be checked against volume and use temperature.
Typical use cases
- Replace adhesive magnet-to-cover assembly with an in-mold two-shot unit
- Hold magnet-to-shaft concentricity by mold pins rather than manual fit
