How to judge whether the precision casting is qualified?

Stainless steel precision casting is actually using the development of the modern production industry, so the development of this production technology is rare at first, because it requires a very precise casting process to cast, so The surface of the precision castings produced is very smooth and precise, and can be better applied to the market when used! The main process of precision casting is silica sol precision casting.
There are many kinds of such precision casting techniques. One of the most important ones is the precision casting of silica sol. Although its various processes are the same, the final effect is the same, and it is hoped that it can be made very precise. The products come out, but how do you detect whether these instruments are made standard?
The first point is that the naked eye can directly see whether the surface treatment of the casting is in place and there is a lack of clear defects. The second point is that there are some small cracks on the panel and some linear shapes on some parts. Defects, etc. As for these very small problems, you can feel that the product is unqualified, so you can imagine how strict the requirements are when making!
