Metal type aluminum alloy gravity castings

Casting can also be divided into gravity casting and pressure casting according to the pouring process of molten metal. Gravity casting refers to the process in which molten metal is poured into a mold under the influence of the earth's gravity, also called casting. Gravity casting in a broad sense includes sand casting, metal mold casting, investment casting, lost foam casting, mud mold casting, etc. Gravity casting in a narrow sense refers specifically to metal mold casting. Pressure casting refers to a process in which molten metal is injected into a mold under the action of other external forces (excluding gravity). Pressure casting in a broad sense includes pressure casting of die-casting machines, vacuum casting, low-pressure casting, centrifugal casting, etc. Pressure casting in a narrow sense specifically refers to metal mold pressure casting of die-casting machines, referred to as die-casting. The precision casting factory has long been engaged in gravity casting of sand molds and metal molds. These casting processes are currently the most commonly used in non-ferrous metal casting and are also the least expensive.
