Specification for all-silica sol precision casting

All-silica sol precision casting is a high-precision, high-quality casting process suitable for manufacturing parts with complex shapes and high-precision requirements. The following are some common all-silica sol investment casting specifications:

1. Material selection: According to the requirements of the parts and the use environment, select suitable materials, such as stainless steel, alloy steel, aluminum alloy, etc.

2. Mold design: Design a suitable mold according to the shape and size of the part, including mold core, template, gate, etc.

3. Mold manufacturing: Manufacture high-precision molds to ensure that the size and surface quality of the molds meet requirements.

4. Sol preparation: According to material requirements, prepare appropriate sol, including sol concentration, pH value, etc.

5. Glue coating: Apply the sol on the surface of the mold to form a uniform glue film.

6. Curing: Place the glue-coated mold in an environment of constant temperature and humidity to solidify the sol.

7. Sintering: The cured mold is sintered to make it hard and wear-resistant.

8. Melting and pouring: Melt the appropriate metal material, and then pour the molten metal into the mold for pouring.

9. Cooling and solidification: After the metal has cooled and solidified, remove the parts.

10. Post-processing: Perform post-processing processes such as degumming, trimming, and heat treatment on the parts to achieve the required size and performance.

11. Inspection and quality control: Inspect the parts in terms of size, appearance, mechanical properties, etc. to ensure that the quality of the parts meets the requirements.

The above are some common all-silica sol precision casting specifications. Specific specifications should be adjusted and optimized according to specific parts and requirements. In actual operation, parameter adjustments and process improvements need to be made based on experience and actual conditions.
