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.

A 20mm drill rod typically refers to a cylindrical tool made of high-strength steel, designed for use in drilling operations. Its 20mm diameter strikes a balance between robustness and manageability, allowing it to penetrate materials while maintaining sufficient structural integrity. The rod can be produced in various lengths, which can be tailored to the specific requirements of a drilling project. Additionally, many manufacturers offer drill rods with various coatings or treatments to enhance wear resistance and durability, making them suitable for use in harsh environments.
