(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).

One of the most significant benefits of aluminium sand casting is its cost-effectiveness, especially for small to medium production runs. The sand mould can be reused multiple times, which minimizes material waste. Additionally, sand casting allows for greater design flexibility compared to other casting methods, making it easier to create intricate and complex geometries.

Conclusion

Prototype sand casting is a type of sand casting that focuses specifically on creating prototypes or models of metal parts. The process begins with the preparation of a sand mold, which is made from a mixture of sand, clay, and water. The sand is packed around a pattern, usually made of metal or plastic, to create a hollow cavity in the desired shape of the final product. Once the mold is formed, it is removed from the pattern, and molten metal is poured into the cavity. After the metal cools and solidifies, the mold is broken apart to retrieve the cast part.
