Surface treatment technology of Metal Division

To the quality of the metal parts further weight saving, corrosion resistance and heat resistance. Environmental measures like hexavalentchromium-free is perfect.

Trivalent chrome passivation

Eco-friendly plating technology which has high heat resistance and good adhesion with painting.

The hexavalent chromium, which were previously being used in anti-corrosion treatment of the car, toxicity and carcinogenicity had been a problem. Since July 2007, EU decided that they do not use hexavalent chrome for automobiles in EU and this movement has been spread to Japan. In Kakihara, efforts to hexavalent chrome-free technology quickly in response to this movement and introduce trivalent chrome chemical conversion treatment to the entire line already.

Super throwing power zinc plating

Corrosion resistance is improved by uniform plating and unfitting is also decreased.

Kakihara quickly started mass production of the plating line of this type in Japan. Corrosion resistance is improved by having become the uniform of the plating thickness by this technology and we have also succeeded in dramatically of poor fit. In addition, this technology provide improvement of plating thickness of the pipe inner surface and superior plating to casting, it made great achievements. Moreover, it can plating on a stainless steel that is normally can not be obtained around with plating.

Nickel-zinc alloy plating

While maintaining the advantages of zinc plating, corrosion resistance up in alloying with nickel.

While maintaining excellent characteristics of zinc plating, it has achieved high corrosion resistance by alloyed with nickel. This plating has a corrosion resistance equal to or greater than than the zinc composite coating, therefore, high cost performance plating is now available. I It is an ideal technology to the engine and lower body of automobiles to be used in harsh environments. In addition, there is a feature for trivalent chrome chemical conversion treatment is possible, that is environmentally friendly.
