Production requirements and material selection of gravity casting
Gravity Casting Pistion In the process of using gravity casting, it mainly refers to the effective injection process of molten metal into the mold under the action of the gravity of the earth. To some extent, it is also called gravity casting. Gravity casting in broad sense includes sand casting, metal casting, investment casting, EPC, mud casting, etc.; gravity casting in narrow sense mainly refers to metal casting. In the production of gravity casting, there are many processing methods of products made of metal materials, such as casting, forging, extrusion, rolling, drawing, stamping, cutting, powder metallurgy and so on. Among them, casting is the most basic and commonly used process. To some extent, gravity casting can effectively inject the molten metal into the hollow mold made of high temperature resistant materials, and the products with expected shape can be obtained after condensation, which is called casting. The product is a casting. Casting can be divided into
