2) The wax liquid of the pouring system is generally recycled wax liquid. When using A1 mandrel to hang the wax, the temperature of the wax liquid should be controlled at 50±5℃. The thickness of each layer is 3~4mm (according to the process documents when special requirements are required), and then put it in water to cool. The wax immersion time depends on the thickness. The cold water tank should be mixed with a washing powder aqueous solution with a concentration of 0.5% to 0.8%.

However, while sand casting is beneficial, it is not without its challenges. The quality of the final product can be influenced by various factors, including the type of sand used, the accuracy of the pattern, and the pouring technique. Therefore, careful attention must be paid to the entire process to minimize defects and ensure the integrity of the cast parts.

In summary, green sand iron casting stands out as a reliable and efficient casting method used across various industries. Its cost-effectiveness, versatility, and capability to produce high-quality castings make it an essential process in metalworking today. As technologies evolve and environmental concerns grow, the industry continues to develop more sustainable practices to enhance the benefits of green sand casting while mitigating its environmental impact. The future of this casting technique remains bright, poised for innovation and continued relevance in the manufacturing landscape.
