Solution - Bright Gold plating (metallization) containing Cobalt

Because the electrical cables for lamps used in medical treatments corroded and broke within a few hours under high humidity, the cable units had to be replaced daily. Company E had approached several companies for a plating solution, but none could provide an effective answer.

One of our customers introduced us to Company E, saying "If Mitsuya can't solve this problem, Company E will have to give up!"

The solution required ensuring durability for over 1,000 hours in an environment with nearly 100% humidity, such as a disinfectant-filled atmosphere. The plated material was a special metal prone to oxidation and had to withstand bending into various shapes during operation.

To meet these demanding requirements, our technical depeartment quickly developed a process that met the specifications and successfully established mass production within just two days.
