Overmoulding vs Press Fit: Two Ways to Get Rubber Onto a Finisher Plate
Both produce a metal-faced pedal pad. They differ in tooling, in retention and in how easily the part can be pulled apart.
Overmoulding
The metal face goes into the rubber tool, and the compound is moulded onto and through it. What comes out is one part. There is no adhesive line, and the insert cannot be levered out without destroying it.
Press fit
The insert is moulded separately and pressed into a recess in the plate. Fewer tool complications, a simpler moulding cycle, and the freedom to sell plate and insert in different combinations — at the cost of a joint that exists.
Choosing between them
Visible, small or pryable inserts, and anything facing a pull-off requirement, should be overmoulded. Large inserts well retained by their own geometry, and low-volume programmes, are usually press fit. We produce both.
Getting the fit right
On a press-fit part the recess and the insert are dimensioned on one drawing, not two, and the interference is verified on prototype parts — 4 weeks from a prototype tool — before any production tool is cut.

A sport pad has a metal face; a rubber pad does not. That single difference drives tooling count, unit price and how the part is validated.
