aluminum castings in the machinery industry. Hangzhou Hongcheng Pml Precision Mechanism Ltd, as a manufacturer of aluminum casting, provides aluminum casting, low pressure cast aluminum, gravity casting and many other services. Finally, high quality aluminum castings are made for automobile industry and machinery industry.

  and   low pressure cast aluminum is a kind of casting method to make liquid aluminum alloy fill aluminum mold cavity and solidify process to obtain high quality castings under the effect of lower pressure. The working temperature of the metal mold is basically controlled at 200~2500 C, when the thin-walled complex parts are casted, the temperature control range is 300~3500 C. It is necessary to control the time to maintain the pressure, too short and too long. The control of supercharging and supercharging speed should be carried out in an effective range.

    through low pressure casting aluminum, the aluminum castings are good in formability, which is beneficial to the formation of Mao Pei with clear outline and smooth surface. Moreover, the structure is dense, the mechanical property is high, the processing rate of the raw material is higher, the general condition does not need the riser, the utilization ratio of the raw material is greatly increased, the rate of receiving is generally up to 90%. In addition, gravity casting is also a common method for casting aluminum. In general mills, aluminum ingot is made into aluminum water and molded from top to bottom in the hub model. The internal porosity of aluminum castings is small, and the degree of pre heat treatment can be greatly improved, even more than that of die-casting products, which is the characteristic of gravity casting aluminum.
