One of the key advantages of water well drilling is its ability to provide a self-sufficient source of water. Unlike surface water sources, which can be subject to seasonal fluctuations and contamination, groundwater generally remains stable throughout the year. This stability is particularly critical in agriculture, where access to water can determine crop yields and, consequently, food security. Farmers who drill their own wells can better manage their water resources, applying water more efficiently to their crops and thereby enhancing productivity.

It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.
