15. CERTIFICATE
All certificate related with material heat treatment and plating is required
From 2017, we established an intelligent workshop with all automatic machined. There are five lines only for producing exported products. The new workshop is executing 6S strictly. The production capacity will be 1500 tons per month.
From 2016, we have imported continous chrome plating line from Italy which is the first one in China.
