Plating for sliding parts

Company O, which manufactures construction-related parts, came to Mitsuya for resolving the sliding part problem.
The part called a sliding board, and was the contact terminals consisted of gold (cladding material, the thickness of 20μm).
Company O had a claim that the sliding contacts cannot be guaranteed the anti-wear for one year, this company hoped us to improve the life of the part by using plating technology.
Without wear on a special metal alloy wire used for the sliding contact, the frequency of replacement of the sliding board was required just 3 years (not more than 3years and not less than 3 years).
Plating specifications proposed by our technical department succeeded to satisfy the required quality and furthermore 76% of the cost down.
