Prevent rust on uncoated areas of hard chrome! Contributes to cost reduction throughout the entire product manufacturing process.
In conventional products, hard chrome plating is applied to stainless steel for corrosion resistance. However, there was a challenge in trying to change the material to iron to reduce material costs, as the product has many bent and welded parts, resulting in areas without hard chrome plating. To address this, Sun Industry performed electroless nickel plating as a base layer and then applied hard chrome plating on top of it. As a result, while changing the material from expensive stainless steel to iron (SPCC), we were able to provide wear resistance and corrosion resistance equivalent to conventional products, contributing to cost reduction throughout the entire product manufacturing process.

basic information
【Proposal】 ■ By applying electroless nickel plating as a base layer, the corrosion resistance of areas where chrome plating does not adhere will be improved. ■ By using a two-layer plating, corrosion from cracks in hard chrome can also be suppressed, enhancing overall corrosion resistance. ● For more details, please visit our company website and contact us.
