The advantage and characteristics of permanentmold casting
Permanent mold casting is the process that the metal liquid is injected into the mold under the gravity of the earth. The generalized Permanent mold casting include sand casting, metal mold casting, investment casting, lost foam casting, mud casting, etc.; narrow righteousness permanent casting mainly refers to the metal mold casting. 1. The metal materials made of product process method, many, such as casting, forging, extrusion, rolling, drawing, punching, cutting, powder metallurgy and so on. Among them, the casting is the most basic, the most commonly used process. 2 the molten metal is injected into a hollow mold made of high temperature resistant material, and the product of the expected shape is obtained, which is cast. The resulting product is cast. 3 casting can be divided into a black metal casting (including cast iron, cast steel) and non-ferrous metal casting (including aluminum alloy, copper alloy, zinc alloy, magnesium alloy, etc.). Precision casting factory specializing in non-ferrous metal casting, focus is on aluminum alloy and zinc alloy casting. There are 4 casting according to mold casting material for sand casting and metal mould. Precision casting plant for these two kinds of casting process are handy, and to design, manufacture these two types of casting mold. 5 casting can also be divided into gravity casting and pressure casting by the casting process of the metal liquid. Gravity casting is the process that the metal liquid is injected into the mold under the gravity of the earth. The generalized gravity casting include sand casting, metal mold casting, investment casting, lost foam casting, mud casting, etc.; in narrow sense gravity casting refers specifically to the metal type casting. Pressure casting refers to the process of the metal liquid in the casting process under the action of other external forces (without gravity). Generalized pressure casting including die-casting machine pressure casting and vacuum casting, low pressure die casting, centrifugal casting etc.; in narrow sense pressure casting designed die casting machine type metal pressure casting, referred to as the die casting. Precision casting factory engaged in sand mold and metal mold gravity casting. These are the most commonly used in non-ferrous metal casting process, but also the lowest price.
