The role of additives in the production process of meticulous machining will no longer be limited to helping the shell to quickly establish wet strength, but also to improve the direction of its investment casting quality, silica sol shell surface quality is good and its high temperature. The high temperature deformation resistance of meticulous machining is good, and the product requires a relatively good precision process. In practice and theory, we should increase the understanding of the meticulous casting process, constantly supplement its technical attempts, and enrich its practical experience.

Meticulous machining is a kind of fine castings with excellent production. Such products have been widely used in industrial production. Meticulous machining has good stable performance. The value of its products is more widely adapted to the pH range, and the stable storage time is relatively long.

Meticulous machining has strict requirements on the shell environment and wind speed. For castings with slender holes, the interlayer drying time needs to be appropriately extended. The better the high-polymer additives can help reduce the defects of the shell and castings. Meticulous mechanical processing requires less maintenance during storage, which can adapt to high shear stress stirring and further shorten the inter-layer drying time of the product, but they can shorten the inter-layer drying time to 1h for such enhanced silica sol.

Machining installation sequence and process

To arrange the detailed machining sequence, we need to follow the basic principles of "surface before hole" and "coarse before fine.

Mechanical processing technology Heat treatment process

With the development of aerospace, industry, microelectronics industry, modern and biological engineering technology, the demand for/detailed mechanical parts (feature size in micron to millimeter level) is increasingly urgent. The specificity of its structure and shape, the diversification of parts and materials, and the accuracy of size and surface quality have become the obvious characteristics of high-precision mechanical parts and their micro-devices and equipment, and the requirements in terms of use function, material characteristics, structure and shape, and sex are also getting higher and higher.

Machining details, forging and casting

In the process of meticulous machining, its mechanical properties are better than cast iron, but the cast iron properties of this material are poor, and the melting point is higher than other materials. There are many problems that need to be paid attention to in the process of processing, mainly because the flow performance of molten steel is relatively poor. In the process of processing, in order to prevent insufficient pouring or cold insulation from meticulous machining, the wall thickness of meticulous machining cannot be less than 8mm. The structural force of the gating system is relatively simple, in the process of using the equipment in the cross-sectional size of cast iron is large, so in the process of processing can also be used in the hot casting mold or dry casting mold.
