What is low pressure casting of stainless steel casting

In stainless steel casting, low-pressure casting technology refers to a method of installing compressed gas on the seal to generate low pressure on the surface of the stainless steel metal, so that the melt on the pipe fills the casting tank, and then controls the solidification. This casting method can reduce the shape of collapse, and it is easy to cast larger and more complex products. There is no environmental pollution during the production process, and automatic modeling is easy to achieve. But the cost of this equipment is too expensive.

Low pressure casting has several advantages:

1. Stainless steel filling is stable.

2. The advantage of molding is that there are no obvious defects on the surface of the product, the outline is smooth and clear, and the appearance is beautiful.

3. It has advantages for some products that require thin-walled shapes.

4. Casting products have high density and good performance.

5. The recovery rate of raw materials for stainless steel castings increases, and the recovery rate of melt increases, which will not cause unnecessary waste. The working conditions are good, the equipment is simple, and mechanical automation is easy to implement.

However, the disadvantages are also obvious. Because high-temperature-resistant equipment requires special heat-resistant materials, the production cost of this kind of production equipment is very high, which also leads to the reason why the equipment is expensive. Although automatic production can be done, the efficiency of this method is not Very high, so production costs are high.

These are the advantages and disadvantages of low-pressure casting in the stainless steel casting process. The advantages and disadvantages are obvious, but overall they are of great help in improving product quality. High quality brings high prices, it seems, not only in life, but also in production .
