1. Aerospace Industry Precision casting is widely used to manufacture components such as turbine blades, structural components, and fittings where accuracy and weight are critical considerations.

- Investment Casting Although not as common, certain types of foundry sand can be used in the investment casting process, providing a reusable mold that enhances the surface finish of the final product.

5. Evaluate Costs While die casting often proves to be a cost-effective solution, it’s essential to weigh the price against the quality and long-term value of the parts you are purchasing.

4. Ejection and Finishing After solidification, the mold opens, and the finished part is ejected. Additional finishing processes such as trimming, machining, or surface treatment may be employed to enhance the product’s quality.

(3) The influence of mould making on the linear shrinkage rate of castings: a. The influence of wax injection temperature, wax injection pressure and pressure holding time on the size of investment mold is obvious in the wax injection temperature, followed by the wax injection pressure, and the pressure holding time is guaranteed After the investment is formed, it has little effect on the final size of the investment. b. The linear shrinkage rate of wax (mold) material is about 0.9-1.1%. c. When the investment mold is stored, there will be further shrinkage, and its shrinkage value is about 10% of the total shrinkage, but when stored for 12 hours, the investment mold size is basically stable. d. The radial shrinkage rate of the wax mold is only 30-40% of the lengthwise shrinkage rate. The wax injection temperature has a far greater influence on the free shrinkage rate than the hindered shrinkage rate (the preferred wax injection temperature is 57-59℃, The higher the temperature, the greater the shrinkage).

1. Speed One of the most significant benefits of rapid sand casting is the reduced lead time. The traditional sand casting process can take weeks, from pattern creation to final product. In comparison, rapid sand casting can produce molds in a matter of days or even hours, enabling manufacturers to bring products to market faster.
