About Us
As professinal suplier of metal castings, we developed backup rings and Mechanical Joint assecorreis for HDPE pipe industry. Backup rings are made by sand casting or investment casting process, and ductile iron glands are made by sand casting too. All products will be full inspected in workshop.
