Disappearance of casting mould casting and advantages of V method
V method casting and casting compared with traditional sand casting, has the following advantages: A high efficient and clean energy production. Using the method of V and EPC technology can make the dry sand repeated use, without drying type, coal consumption is reduced, but because of the long-term vacuum machine, power consumption increases slightly, but significantly reduce dust, saves the manpower capital, the casting work more effectively, save labor and reduce labor intensity, in the casting process of harmful less gas, truly realize the green production. Two. Because of the use of negative pressure casting, sand holes are less high compactness, smooth surface, clear outline, and accurate size; V process key points of the production is selected vacuum pumping system, when the vacuum pumping system, must first determine the vacuum pump capacity, mainly consider the following factors: 1, casting size and shape; 2, while the number of casting mold; Sand box 3, need to work under vacuum at the same time and the number of dimensions; Mold surface permeability 4, close to the film, it controls the amount of air into the mould through the gaps on the plastic film, so in the casting, it is necessary to use a small amount of mold coating, it helps to provide a "vacuum machine auxiliary sealing layer".

V method casting and casting compared with traditional sand casting, has the following advantages:

A high efficient and clean energy production. Using the method of V and EPC technology can make the dry sand repeated use, without drying type, coal consumption is reduced, but because of the long-term vacuum machine, power consumption increases slightly, but significantly reduce dust, saves the manpower capital, the casting work more effectively, save labor and reduce labor intensity, in the casting process of harmful less gas, truly realize the green production.

Two. Because of the use of negative pressure casting, sand holes are less high compactness, smooth surface, clear outline, and accurate size;

V process key points of the production is selected vacuum pumping system, when the vacuum pumping system, must first determine the vacuum pump capacity, mainly consider the following factors:

1, casting size and shape;

2, while the number of casting mold;

Sand box 3, need to work under vacuum at the same time and the number of dimensions;

Mold surface permeability 4, close to the film, it controls the amount of air into the mould through the gaps on the plastic film, so in the casting, it is necessary to use a small amount of mold coating, it helps to provide a "vacuum machine auxiliary sealing layer".
