Four common casting methods of silica sol forging

With the advantages of high specification, high precision good process performance, the bucket tooth casting supplier silicasol forging is an advanced process with few no drilling, which is widely used. The selection of silicasol forging method can save a lot of mechanical equipment comprehensive working hours of production processing, as well as greatly save metal materials raw materials. Silica sol forging is a widely used precision casting method in the precision casting industry, which can reasonably reduce the cost improve the competitiveness of precision casting companies. Casting forming is an important process in the process of silica sol forging, so what is the general casting method of silica sol forging?

1. Crystal formation under working pressure

The bucket tooth casting manufacturer puts the shell into the working pressure tank for pouring. After the pouring, immediately close the pressure tank enter the high pressure gas rare gas into the tank to make the casting condense under the working pressure, so as to expand the relative density of the casting.

2. Vacuum pump breathing pouring

The shell is placed in the vacuum pouring box, according to the micro porosity in the shell, the steam body in the die is extracted, so that the shape memory alloy can fill the die as soon as possible, copy the appearance of the die, improve the precision of the casting parts, avoid the defects of porosity insufficient pouring. This kind of way is more common overseas.

3. Definite crystal

Some investment casting parts such as turbine engine leaves, magnetic tiles, etc. if their crystal structure is columnar crystal arranged in a certain direction, their working characteristics can be improved a lot. Therefore, the technology of investment casting fixed crystal is developing rapidly.

4. Hot type force pouring

It is a common pouring method, that is, after the shell is removed the calciner, the pouring is carried out at high temperature.
