16. CERTIFICATE
All certificate related with material heat treatment and plating is required
We have complete piston rod manufactured equipment covering all processes. The critical processes of heat treatment and chrome plating are finished in our own company, which ensure the quality control of the key technical requirements
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!
