Abstract
The invention is directed to an overmolded two-component friction element in a plastic pallet and to a method for forming the pallet. The friction element includes a rigid outer carrier member and an elastomeric material that is exposed at one or more ends. The friction element is first formed in an injection mold, and then is placed in a pallet mold. Resin is injected into the pallet mold around the sides of the friction element leaving the exposed elastomeric material form part of the pallet surface.

A method of forming a transportation system with an over-molded friction element comprising:
- forming a rigid outer carrier member of a first friction element, the rigid outer carrier having a central channel defining a drain and a first upper cavity and a second lower cavity;
- injecting an elastomeric material into the first cavity and the second cavity of the outer carrier member of the first friction element;
- moving the rigid outer carrier member with the elastic material in the cavity of the rigid outer carrier member into a mold for a transportation system;
- and,
- molding over an outer surface of the carrier member of the first friction element that was moved into the mold for the transportation system so that a first portion of the elastomeric material in the first cavity of the first friction member is exposed on an upper surface of the transportation system and a portion of the elastomeric material in the second cavity of the first friction member is exposed on a lower surface of the transportation system.
A method of forming a pallet with friction elements comprising:
- forming a plurality of friction elements having an outer rigid carrier member with a drain channel and injecting an elastomeric material in a cavity of the outer rigid carrier member;
- and,
- positioning the plurality of friction elements having an outer rigid carrier member with a drain channel and injecting an elastomeric material in a cavity of the outer rigid carrier member into a pallet mold and injecting a resin into the pallet mold.
