Insert molding
Insert molding places a metal or plastic insert into the mold and encapsulates it with resin. It reduces assembly steps and can improve strength at threads, connectors and mounting points.
What we review
- Insert type: threaded, bush, pin, connector or custom
- Insert placement and retention in the tool
- Pull-out and torque requirements
- Resin choice and shrinkage around the insert
- Gate location and flow direction
Typical applications
- Threaded bosses in enclosures
- Metal bushings and mounting points
- Connectors and terminals
- Structural inserts in industrial parts
What to send
Part drawing, insert drawing or specification, material, quantity and any pull-out/torque requirement. Tell us whether inserts are supplied by you or sourced by us.
FAQ
Can you source the inserts?
Possibly. Send the specification; sourcing and approval are confirmed before tooling.
How is insert position controlled?
The tool and fixture control position. Critical dimensions and pull-out requirements are agreed before the build.
