Gravity casting refers to the process of injecting molten metal into a mold under the influence of the earth's gravity, also called gravity 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 mainly refers to metal mold casting.

1. There are many process methods for making metal materials into required products, such as casting, forging, extrusion, rolling, drawing, stamping, cutting, powder metallurgy, etc. Among them, casting is the most basic and commonly used process.

2. Inject the molten molten metal into a hollow mold made of high-temperature resistant materials, and after condensation, a product of the desired shape is obtained. This is casting. The resulting product is a casting.

3. Casting can be divided into ferrous metal casting (including cast iron, cast steel) and non-ferrous metal casting (including aluminum alloy, copper alloy, zinc alloy, magnesium alloy, etc.) according to the material of the casting. The precision casting factory specializes in non-ferrous metal casting, focusing on aluminum alloy and zinc alloy casting.

4. Casting can be divided into sand casting and metal mold casting according to the material of the casting mold. Precision casting factories are proficient in both casting processes and design and manufacture these two types of casting molds by themselves.

5. 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 and vacuum casting of die-casting machines, 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 cheapest.
