Abstract:
A compression shoe for use on a concrete products forming machine comprises a main body and a plated layer overlaid on the main body. The main body is configured to be slidingly received within a mold cavity of a concrete products mold. The plated layer overlaid on the main body of the compression shoe comprises a uniform electroless nickel (Ni), phosphorus (P), and polytetrafluoroethylene (PTFE) nano dispersion coating to effect enhanced material release characteristics by preventing the build-up of material on the compression shoes and enhancing their wear characteristics.
