Benefit mutually and go forward hand in hand.
We imported one continous chrome plating line from Italy at the beginning of 2016. With this new chrome plating line, we will improve efficiency and product quality a lot.The new chrome plating line is the first one in China and will be the only one in the next five years!
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.
