On May 23, 2017, the company's board of directors decided to invest an additional 15 million yuan to build a new tidal sand production line. The annual production capacity is increased by 1000 tons of castings, and imported equipment is used throughout the line. Among them, the smelting furnace is ABP's 3-ton one-tow two-induction furnace; the moulding machine and casting cooling line are Japan's original; the automatic pouring machine is Japan's new East original; and the sand drop drum is made by Ericsson Germany.
