The process of mechanical processing and manufacturing.
Author:
In the process of detailed machining, the role of additives will no longer be limited to helping the shell mold establish wet strength, but will also promote the development of its investment casting quality. The surface quality of silica sol shell is good at high temperatures. The high-temperature deformation resistance of detailed machining is quite good, and the products require relatively good precision processes. Both in practice and theory, there should be an increased understanding of detailed casting processes, continuously supplementing technical attempts and enriching practical experience.
Detailed machining is a method for producing high-quality detailed castings, and such products are widely used in industrial production. Detailed machining has very good stability, and the value of its products adapts to a wider pH range, with a relatively long stable preservation time.
Detailed machining has strict requirements for the shell-making environment and wind speed. For castings with slender holes, the interlayer drying time needs to be appropriately extended. High polymer additives can better help reduce defects in the shell mold and castings. The maintenance workload required during the preservation period of detailed machining is relatively small, which can adapt to high shear stress stirring, further shortening the interlayer drying time. However, they can shorten the interlayer drying time of such enhanced silica sol to 1 hour.
