Inside the Company
The finish of castings has always been a big problem for foundry manufacturers and casting users. In this regard, the major foundry manufacturers in the casting process also tried to take a variety of programs. Such as: the use of sand blasting process, the use of casting paint and other methods.
The founding predecessors of Baozhu sand developed Baozhu sand after the improvement of raw material formula and the adjustment of particle size distribution, and successfully introduced Baozhu sand into the casting industry, which easily solved the problem of casting finish.
Advantages of jewel sand: First of all, jewel sand has good roundness, good spherical shape and smooth surface; Ultra-low expansion rate and reliable thermal stability; Good fluidity, small specific surface area and less gas emission; Good collapsibility and non-sticky sand; It can not only improve the smoothness of castings, but also improve the precision. It is the best choice for casting technology.
Precision requirements are not too high castings, in order to save the cost of sand, can be used with traditional quartz sand. Only in the required precision parts, high strength special-shaped parts, bottlenecks (such as: complex structure of the sand core) and other easy to stick sand, not easy to clean the grinding to the place, the use of Ceramsite sand, in order to achieve the best cost performance.
Significant benefits two:
Two lifting and two lowering
Two mentions: greatly improve the smoothness and precision of castings; directly increase the output of castings;
Two drops: significantly reduce the labor and time costs of cleaning and polishing; directly reduce the cost of casting manufacturing processes.
