The low pressure casting machine is widely used in the production of aluminum, copper and zinc alloy castings in automobiles, motorcycles, instrumentation, textile machinery and aerospace industries. The principle of the low pressure casting machine is mainly to fill the sealed protective furnace with a certain amount of dry compressed air. Under the action of air pressure, the metal liquid in the holding furnace is punched into the mold cavity along the liquid riser to make the metal liquid in the mold cavity. It solidifies internally (under pressure) to obtain a compact casting. Next, Delin Machinery will show you what are the common faults of low pressure casting machines and what solutions are there.
