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.

Social connections are another fundamental pillar in the framework of resilience. Humans are inherently social beings, and the support of friends, family, and community can provide a cushion during tough times. Engaging with others fosters a sense of belonging and purpose, which can give individuals the strength to overcome adversities. This network of support allows individuals to share their burdens and feel less isolated, making the challenges of life more manageable.
