The low-pressure casting machine is a general-purpose equipment for low-pressure casting of aluminum alloy profiles. It can be used in the production of aluminum alloy profile castings in the production of trolleys, motorcycles, instrument panels, textile equipment and aerospace industry. The low-pressure casting machine is composed of a server, a hydraulic transmission system, a pool-type holding furnace, a liquid level charging device, an electrical system, and a grinding and cooling system.

The contemporary low-pressure casting machine combines computer information technology and fully automatic control system. It has been able to accurately simulate the full process of simulated forging and repeated re-charging curve. Some low-pressure casting machines also contain self-diagnosis of common faults. The development of low-pressure casting machinery and equipment has also promoted the use of low-pressure casting.
The key to the low-pressure casting machine consists of a sound card frame, a holding furnace, an open-close type organization, a hydraulic transmission system, a charging system software, and an electrical system.

There are two key types of holding furnaces for low-pressure casting machines: this is a graphite crucible holding furnace, which is commonly used in two models of 400 kg and 350 kg; the other is a holding furnace for fireproofing materials, from 400 kg to 1500 kg. Volume. The advantage of graphite crucible is not moisture, the defect is short life, usually not more than 6 months. The fireproof material of the fireproof material lining has a large volume, and the furnace lining has a long service life, and can usually be applied for about 5 years. The defect is easy to get wet, and the heat insulation is also required when the forging is shut down.

The specifications and models of aluminum alloy ruts are getting bigger and bigger. At this stage, China has produced ruts of 24.5In. Therefore, after selecting low-pressure machines, the open-close type structure should be any large. Today's low-pressure machines have widely used hydraulic cylinders as open-closed structures. The hydraulic cylinders operate stably, the working pressure value can be adjusted, and the allowable open-type range is wide.
