The role of Silica Sol Investment Casting

Although silica sol investment casting technology started late in China, it has made great progress in recent years and has a very bright prospect. Silica sol precision casting requires high machining accuracy. Therefore, silica sol precision casting should strengthen its understanding of its theory and practice, and continuously supplement its professional knowledge.

Silica sol precision casting is a very rich experience. When using it, you can sort out the entire production process of silica sol investment casting and forge better products. When adding it, you need to evaporate the air bubbles, and then Decomposition will produce a large number of small molecule gases and bubbles.

This substance is harmful to the human body, so in the usual work, the workers must strictly abide by it. No matter whether the silica sol precision casting mold is used or auxiliary, it must be done according to their own requirements. In the production At this time, use these things flexibly.

In complex thin-walled castings, in order to effectively improve the air permeability of precision castings, a vent can be opened at a higher place, so that the gating system can be reasonably arranged to prevent air jets.

When silica sol precision casting is used in military industrial silica sol precision casting, the pouring temperature is appropriately increased, the distance between the gate and the gate is reduced, and the pouring rate is effectively reduced, thereby ensuring the stable filling of the metal liquid.

The mold of silica sol investment casting must be complete, and there must be enough high temperature when using it, so as to ensure the complete combustion of the precision casting shell, so that the gas can be completely discharged, and the baked shell is white or light Gray with no black spots.
