According to IMPCO, manufacturers and platers of powder metal parts can realize near zero reject rates for plated parts using the company’s new impregnation process. The procedure utilizes a unique combination of resins, cleaning technologies and process controls designed to collectively prevent spotting, bleedout and other plating defects.

Powder metal manufacturers and platers who use the IMPCO impregnation process are said to decrease finishing costs and increase productivity because fewer intermediate steps are required for full plating coverage, giving better decorative finishes and achieving higher corrosion resistance.

IMPCO’s PoreSeal resins are formulated for the sponge-like attributes of P/M porosity, and the impregnation process is fine-tuned combining proprietary, thorough rinsing techniques, which are automatically matched to the various densities of the parts produced by powder metal part manufacturers. The result is a higher fill (nearly 100%) of complex porosity, thus forming an impenetrable base for subsequent finishing processes, according to the manufacturer.
