https://www.zj-kaida.com/capabilities/casting/ Permanent mold casting is a brass casting process that employs reusable “permanent” brass molds. It is often referred to as gravity die casting because brass is typically poured into the die under gravity-induced pressure instead of using forcible injection. Some manufacturers use other processes as well, such as pouring molten brass under high gas pressure or vacuum pressure. Login Login 0 repins 0 comments 0 likes
