What do you need to know about Low Pressure Casting Machine?

Low Pressure Casting Machine is a type of casting machine that uses low pressure (up to 0.8 bar) to feed molten metal into a mold. It is widely used for producing aluminum and copper alloy castings with complex shapes and high quality. In this article, we will introduce the functions, characteristics and working principle of air injection machine.

What are the functions of Low Pressure Casting Machine?

Low Pressure Casting Machine can perform various functions depending on the application and design. Some of the common functions are:

1. Producing castings with thin walls, smooth surfaces and accurate dimensions.

2. Reducing porosity, shrinkage and gas defects in castings.

3. Saving energy and material by using less metal and avoiding metal loss.

4. Increasing productivity and automation by using computerized control systems and robotic devices.

What are the characteristics of Low Pressure Casting Machine?

Low Pressure Casting Machine has some distinctive characteristics that make it different from other casting methods. Some of the main characteristics are:

1. The mold is usually at or above the level of the molten metal, which prevents oxidation and contamination.

2. The molten metal is fed into the mold through a riser tube that connects to a holding furnace.

3. The pressure is applied to the molten metal until it solidifies in the mold, which ensures uniform filling and feeding.

4. The mold can be either permanent or sand, depending on the casting shape and size.

How does the Low Pressure Casting Machine work?

The working principle of air injection machine can be summarized as follows:

1. The molten metal is heated and stored in a holding furnace that maintains a constant temperature and composition.

2. The mold is preheated and coated with a release agent to prevent sticking.

3. The mold is moved to the casting position and aligned with the riser tube that connects to the holding furnace.

4. The pressure is applied to the molten metal through the riser tube, which forces it to rise and fill the mold cavity.

5. The pressure is maintained until the metal solidifies in the mold, which forms the casting.

6. The pressure is released and the mold is opened to remove the casting.

Low Pressure Casting Machine is a versatile and efficient casting machine that can produce high-quality castings with complex shapes and thin walls. It has many advantages over other casting methods, such as reducing defects, saving energy and material, and increasing productivity and automation. Low Pressure Casting Machine is suitable for producing aluminum and copper alloy castings for various industries, such as automotive, aerospace, electrical, medical and more.
