What types of castings can be cast by Low Pressure Casting Machine?

    Low Pressure Casting Machine casting is a manufacturing process that pours smelted molten metal into a metal mold and solidifies it into a part with the required shape and performance. Forging is a commonly used manufacturing method, and its advantages are: large processing technology coordination capability, low manufacturing cost, and the ability to produce complex shapes and large and medium-sized castings, which accounts for a large proportion in mechanical equipment manufacturing.

  1. Metal mold casting: Metal mold casting grinding tools can be used repeatedly. Each time the metal liquid is poured multiple times, multiple castings are obtained. The service life is long and the productivity is high. Metal-type castings not only have good specifications and smooth surfaces, but also have higher strength than sand-type castings and are less likely to be damaged when the same metal liquid is poured.

 

  2. Pressure forging: Pressure forging refers to a process in which metal liquid is introduced into metal molds under the action of other external forces (which may include force). The pressure forging in the discussion includes pressure forging of aluminum die-casting machines and vacuum pump forging, low-pressure casting, centrifugal casting, etc.; pressure forging in a narrow sense specifically refers to metal-type pressure forging of aluminum die-casting machines, commonly known as aluminum die-casting. These types of forging processes are the most common in rare metal forging at present, and they are the least expensive relatively.

 

 3. Aluminum alloy casting: It refers to the process of introducing metal liquid into metal mold under the action of cosmic force, also called casting. The metal liquid is usually manually poured into the glue inlet, and the mold cavity, exhaust pipe, water cooling, and mold ejection are obtained by using the weight of the metal liquid to fill the mold cavity.

 

Brief description: Differential pressure casting is also called counter-pressure casting and differential pressure casting. It is a casting method derived from low-pressure casting. The difference from low-pressure casting is that a sealing cover is placed outside the Casting mold and filled with compressed gas, so that the casting mold is under a certain pressure of the gas. When the molten metal is filling the mold, the pressure of the gas in the holding furnace is greater than the pressure of the gas in the casting mold, so as to achieve the filling, pressure maintaining and pressurization of the molten metal as in low-pressure casting. However, the casting is crystallized and solidified under higher pressure at this time, so it is guaranteed to obtain a casting with higher density.
