  Coated Sand Casting Production Process

  22-10-31

  The iron mold sand coating production line can also be called the coating sand production line,which metal mold cavity is covered with a thin layer of molding sand. Due to the sand layer is relatively thin (4～8mm),cause to reduces the scrap rate and provides casting quality. Another advantage is,Iron mold sand-covered mold has good rigidity,our casting parts will have high precision than sand cast
