关于低压铸铝件的那些工艺

Low pressure casting process, low pressure casting is to make liquid metal materials fill the cavity under the effect of working pressure to produce castings. Because the commonly used working pressure is low, it is called low pressure casting. The whole process of the processing technology is: in the sealed crucible ( sealed tank), the dry impetuous air is compressed. Under the effect of gas pressure, the metal material liquid 2 rises along the riser 4 to Zhejiang low pressure casting plant. According to the rubber inlet 5, it enters the cavity 8 stably maintains the gas pressure on the liquid level in the crucible until the casting is completely condensed. After that, the gas pressure on the liquid level is eliminated to make the non condensed metal material in the riser flow into the crucible, then the cylinder 12 is used to open the mold issue the casting low-pressure casting parts processing plant.

Low pressure casting is a way to make liquid metal materials fill the cavity under the effect of working pressure to produce castings. Because the commonly used working pressure is low, it is called low pressure casting. The whole process of the processing technology (see Figure 1): in the sealed crucible ( sealed tank), the dry impetuous air is compressed, the metal material liquid 2 rises along the riser 4 under the effect of gas pressure. According to the rubber inlet 5, it enters the mold cavity 8 Hangzhou low pressure aluminum casting factory stably, maintains the gas pressure on the liquid level in the crucible until the casting is completely condensed. Then, the gas pressure on the liquid level is eliminated, so that the uncondensed metal material in the liquid opening pipe flows into the liquid crucible, then the casting is opened released by cylinder 12.
