Powder metallurgy parts because the internal pore, with conventional plating process into the electrolyte to generate internal corrosion, long "backwater", "black spots" and "long hair" and other defects, serious impact on the quality of coating. So the powder metallurgy electroplating has been a problem, the general can not solve the electroplating factory.

After the experimental model for the technical personnel of our company's cable, now we have to solve this problem, we developed a sealing agent, and designed a set of special pore sealing equipment: all our production, after we had "sealing" treatment of powder metallurgy parts. Electroplating factory general can smoothly electroplating.
