What is Gravitational Casting?

Gravitational Casting refers to the process of injecting molten metal into a mold under the influence of Earth's gravity, also known as Gravitational Casting. Generalized Gravitational Casting includes sand casting, metal casting, investment casting, lost foam casting, mud casting, etc; Narrowly defined Gravitational Casting mainly refers to metal mold casting.

There are many process methods for making metal materials into required products, such as casting, forging, extrusion, rolling, drawing, stamping, cutting, powder metallurgy, and so on. Among them, casting is the most basic, commonly used, and widely used process. Casting is the process of injecting molten metal into a hollow mold made of high-temperature resistant materials, condensing it to obtain the desired shape of the product. The resulting product is a casting.

Casting can be divided into black metal casting (including cast iron and 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 non-ferrous precision casting factory specializes in non-ferrous metal casting, with a focus on aluminum alloy and zinc alloy casting.

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

Casting can also be divided into Gravitational Casting and pressure casting according to the pouring process of molten metal. Gravitational Casting refers to the process of injecting molten metal into a mold under the influence of Earth's gravity, also known as casting. Generalized Gravitational Casting includes sand casting, metal casting, investment casting, lost foam casting, mud casting, etc; Narrowly defined Gravitational Casting specifically refers to metal mold casting. Pressure casting refers to the process of injecting molten metal into a mold under the action of other external forces (excluding gravity). Broadly speaking, pressure casting includes pressure casting and vacuum casting of die-casting machines, low-pressure casting, centrifugal casting, etc; The narrow definition of pressure casting specifically refers to the metal mold pressure casting of the die casting machine, abbreviated as die casting. Precision casting factories have long been engaged in Gravitational Casting of sand and metal molds. These casting processes are the most commonly used and relatively inexpensive in non-ferrous metal casting.
