[VA/VE Case] Reduced lead time for parts production by one week through elimination of plating.
The appropriate use of ZAM materials leads to an extension of product life and a reduction in maintenance frequency, contributing to a reduction in total costs.
We propose a chrome plating-free process that eliminates the chromate plating treatment and introduces a case where the production lead time for parts was shortened by one week. In response to frequent requests for short lead times for semiconductor equipment parts, the conventional chromate plating process extended the lead time. While cost reduction was also a challenge, customers particularly highlighted the shortening of lead times as the most critical issue. By changing from conventional steel materials to black ZAM materials with high corrosion-resistant plating, we were able to shorten lead times and achieve cost reductions of up to 10-20%. Furthermore, the dense plating layer unique to ZAM materials exhibits far superior corrosion resistance compared to conventional hot-dip galvanized steel sheets. [Challenges] ■ The conventional chromate plating process extended lead times in response to frequent requests for short lead times for semiconductor equipment parts. ■ Cost reduction and, in particular, lead time shortening are necessary. *For more details, please download the PDF or feel free to contact us.
