A Gravity Casting Machine is a kind of machine, that produce brass faucet, zinc handle, steel auto parts, etc. Next, we will introduce examples in detail.


Gravity casting is a widely used casting process in which (brass molten water etc..) is poured into a mold under the influence of gravity. This is where the name Gravity Casting comes from. The process is known for its ability to produce complex shapes with high accuracy and minimal machining. The success of this process depends heavily on the quality and design of the equipment used.

A gravity casting machine includes a complete set of equipment and molten metal materials that are used to prepare the mold, melt the metal, and pour it into the mold. In this article, we will discuss the key components of gravity-casting equipment and their functions.


Design of gravity die casting machine



Mold preparation:

The first step in the gravity casting machine is preparing the mold. The mold must be designed to accommodate the shape and size of the object being cast. There are several materials that can be used to create mold, including sand, plaster, and ceramic. Each material has its own advantages and disadvantages, and the choice depends on the requirements of the specific casting.

Mold release agents:

Once the mold is prepared, a mold release agent is applied to ensure that the casting can be easily removed from the mold after solidification. There are several types of mold release agents available, including water-based and solvent-based agents.


The metal used in gravity casting is melted in a furnace. The furnace is typically powered by gas or electricity, and the temperature can be controlled to ensure that the metal is melted to the correct temperature and consistency. The furnace is designed to hold a specific amount of metal, which is determined by the size of the casting being produced.


The melted metal is poured into a crucible, which is a container designed to hold the molten metal. The crucible is made of a material that can withstand the high temperatures of molten metal and is typically made of ceramic or graphite.

Pouring system:

The pouring system consists of channels and gates that allow the molten metal to flow from the crucible to the mold. The pouring system is designed to ensure that the metal fills the mold evenly and completely. Molten metal can be poured manually or manipulator. We have poured manually casting machine, poured by a robot arm, and low-pressure automatic casting machine.

Cooling system:

After the molten metal is poured into the mold, it begins to cool and solidify. The cooling system is designed to control the rate of cooling and ensure that the casting solidifies evenly and without defects.


Once the casting has cooled and solidified, it is removed from the mold, and any excess material is removed through trimming and machining. The finishing process may include additional treatments, such as polishing or painting, depending on the requirements of the specific casting.

Molten metal materials:

Brass, copper, zinc alloy, aluminum alloy, iron, steel, cast steel, Non-ferrous and ferrous metals.


Gravity casting equipment is essential for producing high-quality castings with complex shapes and high accuracy. The equipment used in the process includes molds, mold release agents, furnaces, crucibles, pouring systems, cooling systems, and finishing tools.

The success of the process depends on the quality and design of each component, and careful consideration should be given to the selection of each piece of equipment. With the right equipment and expertise, gravity casting can be a cost-effective and reliable way to produce a wide range of metal parts and components.
