The old factory located in Ju County will all be moved to the new address, No. 1, Tungsten Industry Road, Wendeng District, Weihai City, Shandong Province, and the environmentally friendly relocation will be realized in 2017. The power plant has been relocated and the new factory will be officially put into operation in July 2018.
