Prevention and pouring temperature of porosity in silica sol precision casting

    The development trend of silica sol precision casting in my country is relatively late. In the production process, high-precision processing technology is required. Silica sol precision casting must strengthen the understanding of new technologies in terms of concept and operation, and continue to fill the basic technical expertise. common sense.

    Silica sol precision casting enriches its specific work experience. During the application process, the entire production process of precision casting will be corrected, and more powerful and detailed products will be found. During the filling process, the solid model of the foam must be dissolved by vaporization, resulting in a lot of small molecular water vapor and foam ash.

    At a certain level, this ingredient is harmful to people. The actual operating staff must strictly implement the operation guidelines. Whether it is the operation process or assistance or other new safety protection projects, it must be carried out according to the implementation status. During the production process The operating procedures must be mastered.

    In the application process of some complicated and thick-walled castings of silica sol precision casting, in order to better and reasonably improve the ventilation performance of their precision castings, precision casting suppliers can install exhaust vents at high places if possible. , and then effectively set the pouring system software to avoid pouring the gas fan coil.

    In the process of silica sol casting, the pouring temperature can be reasonably increased, the distance between the ladle nozzle and the glue inlet cup can be reduced as much as possible, and the pouring rate can be reasonably reduced, so that the shape memory alloy can be successfully filled.

    Silica sol shell-making should be sufficient, and a very high temperature should be used during the application process to ensure that the precision casting shell is baked and translucent, so that the vapor raw materials of the product can be completely removed, and the detailed shell of cake baking is gray-white or light gray. , no small black spots can occur.
