The process of China gravity casting

As a China gravity casting factory, we can tell you there are three stages to the gravity casting process.

1. The first step is the heating of the mold and coating it with a die release agent. The release agent spray also serves as a cooling agent after the part has been removed from the die.

2. In the second step, the molten metal is poured into channels in the tool to allow the material to fill the entire mold cavity. The metal is either dosed or hand poured by using ladles. Usually, there is a mold “down sprue” that allows the alloy to enter the mold cavity from the lower part of the die. This reduces the formation of turbulence and subsequent porosity and inclusions in the finished part.

3. After the part has cooled, the die is opened by either using a mechanical tool or manually.

As a China gravity casting manufacturer, we can produce and wholesale gravity casting aluminum parts. Looking forward to your orders!
