When can die casting offer advantages over permanent mold castings?
A. Die castings can be made to closer dimensional limits and with thinner sections than permanent mold castings. Holes can be cored in die castings, and they are produced at higher rates with less manual labor. They have smoother surfaces and usually cost less per part. Permanent mold casting, however, involves somewhat lower tooling costs and can be made with sand cores yielding shapes not available in die casting.
