DONGRUN CASTING is one of the leading cast part made of zinc alloy with chrome plated finish manufacturers and suppliers in China. We have customized cast part made of zinc alloy with chrome plated finish made in China, welcome to check the quotation with our factory.

Hard chrome plating is widely used as coatings resistant coating to extend the service life of mechanical parts . However, conventional hard chromium plating process produces hexavalent chromium ions, which is a known carcinogen . Thus, the entire electroplating industry is a major effort to replace hard chrome plating and environmentally friendly , non-carcinogenic coatings have similar or superior to hard chrome . 

Our Zinc die casting parts are chromed with the process.The surface is very nice,similar as mirror. 

A new nano- cobalt-phosphorus -based coatings have been developed pulse plating processes. The resulting nanocrystalline cobalt- phosphorous coating seems to be a very promising alternative to hard chrome , characterized by equal or superior to those hard chrome . However, the nano- crystalline cobalt-phosphorus -based paint in the electroplating process based on pulse plating. In the pulse plating , is applied between the anode and the cathode voltage pulses at different amplitudes at different frequencies. This pulse plating process for the production of nano- cobalt- phosphorous coating requires a special power supply
