One of the Casting Steps, Pouring

Before pouring the molten steel into the mold, it is important to preheat the shell mold to a high temperature, such as 1200 degrees Celsius, to reduce the temperature difference between the shell and the molten steel. This can help prevent cracking or other defects in the finished product. It’s understandable that the melting and pouring workshop can become hot during the process, even in cold weather. In order to help you reduce costs, we will choose to pour at night. The main reason is that the temperature will be relatively low at night, and the temperature in the workshop is not so high. Another reason is that electricity is cheaper at night than during the day in China.
