The primary function of casting sand suppliers is to deliver a product that meets the specific needs of the foundry industry. Suppliers must understand the nuances of different sand types and their applications. For example, fine grained sands provide excellent surface finishes, while coarse grained sands might be preferable for large, thick-walled castings. Furthermore, their knowledge of sand treatment techniques, including reclamation processes, enables them to offer tailored solutions to their customers.

The consumer electronics market also benefits from aluminium die casting. Laptops, smartphones, and other devices frequently incorporate aluminium cast components, which provide strength while allowing for sleek and aesthetically pleasing designs. The excellent thermal properties of aluminium enhance the longevity of electronic devices by aiding heat dissipation and preventing overheating.

(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).
