If large foundries want to obtain high-quality and high-quality products, they must start from the source, especially the quality of raw materials. In addition, every process requires additional attention, especially modeling, molds, melting and pouring, and heat treatment. And so on, are all very important processes. The manufacturer's requirements for molds must be smooth, accurate in size, easy to lift, and moderate inclination;

Because of the large amount of molten steel in castings, safe production is essential. The crane slings used by large foundries must be frequently overhauled and replaced regularly. When the quality of the castings can be guaranteed, the process can be embroidered. Auxiliary materials such as ceramic tubes, good insulation risers and high-quality heat-generating covering agents can improve the quality of castings. These high-quality materials are also very helpful to improve the quality of castings and the process yield rate.
