Information
Ceramic foundry sand is more and more widely used in resin casting, which can control product quality more effectively and accurately, and produce high-quality parts in line with environmental protection. Ceramic foundry sand for resin sand casting can effectively prevent the casting from expanding defects.
     
 
In recent years, some manufacturers of precoated sand in China have added some ceramic foundry sand to the raw sand, so that the shell mold and shell core can have the properties of high temperature resistance, low expansion, easy collapse, high strength and low gas generation. For the core with particularly complex shape, it can also solve the problem that sand shooting is not easy to compact.

In order to meet the requirement of light weight, the problems of misrun and cold shut can be effectively solved by adding some ceramic foundry sand to the facing sand when producing thin-walled iron castings, and the overcooling structure can be avoided.
 
In the aspect of modeling, using ceramic foundry sand instead of silica sand has the following advantages:
 
1. The content of dust in the atmosphere of the workplace is greatly reduced, especially the silicon dust is very little, which is conducive to the health of employees, which will become the focus of attention in the future.
 
2. The raw sand consumption per ton of castings can be greatly reduced and resources can be saved.
 
3. Because the fluidity of sand is good, under the same compaction condition, the compactness of mold and core is improved and the permeability is still good, which is very helpful to improve the quality of castings.

4. The drawing property of molding sand is improved obviously, which can reduce the drawing slope of pattern and decrease the sand dropping during drawing, which is helpful to improve the dimensional accuracy and surface quality of castings.
