Left and Right Roller Overmoulding

A matched pair of rollers, left and right, overmoulded onto a rigid core.

Mirrored parts are usually tooled as a family rather than two separate tools, so both halves come off the same steel and the same process. That removes the risk of one side running to a slightly different dimension than the other.

Bond between substrate and overmould is checked at sampling. Where the two materials meet, surface preparation and melt temperature matter more than pressure.

Send both halves of the 3D, plus the substrate material, for a DFM review.
