Based on theme of further improvement of quality and cost performance such more weight saving, corrosion resistance, heat resistance, fitting etc, plating technology has been developed.
Environmental measure is also prepared like hexavalent chromium-free.
Trivalent chromium chemical conversion treatment
Environment compatible plating technology with high heat resistance and excellent adhesion for paint.
Up to now, usage of the hexavalent chromium for rust proofing for automobile is pointed out as issue of carcinogenic and toxicity. In July 2007, A decision not to use hexavalent chromium for automobile in EU was made and this movement is spreading to Japan. In considering this movement, Kakihara industries co., ltd took the initiative to tackle to hexavalent chromium-free technology and already adopted trivalent chromium chemical conversion treatment to all plating lines.
High uniformity electrodeposition of zinc plating
Rising the corrosion resistance and reduced fitting defect because of improvement of uniformity of plating thickness.
Kakihara industries co., ltd took the initiative to commence mass production by this type of plating line in Japan. By this technology, remarkable results has been achieved such improvement of uniformity of plating thickness, raising the corrosion resistance, sharp decreasing of fitting defect, improvement of plating thickness on inner pipe and obtaining the ability to carry out plating on the casting. It is even feasible to carry out plating on stainless that cannot be treated by usual.
Zinc nickel alloy plating
While inheriting the advantage of zinc plating, improving the corrosion resistance by alloying with the nickel.
Without losing an excellent characteristic of zinc plating as ever, high corrosion resistance and heat resistance can be secured by alloying with zinc and nickel.
Cost is lower compare with composite galvanized film and plating with high cost performance is now feasible due to possessing equal or higher corrosion resistance. it is an ideal technology to be used even under a harsh environment such around engine and lower part of car. Also, it is environment friendly as an another characteristic due to trivalent chromium chemical conversion treatment is feasible.
