How Can We Choose a Reliable Steel Casting Manufacturer?

If we want to see which steel castings are better, we need to judge from many aspects, for example, we can judge from the manufacturer's control of all aspects of the production line, and we can also judge from the production process and casting process of steel castings, as well as the processing after the casting is formed, the inspection after completion, etc., qualified steel casting manufacturers must be able to ensure the internal and external quality of the product.

1. Professional steel casting manufacturers generally use standard models, and will also use the modeling process of sodium silicate sand, and the manufacturers will also brush a special coating layer on the surface of the core to prevent cracking of the castings and ensure that the surface of the casting products can be smooth and smooth;

2. When the steel is smelted, the steel casting manufacturer should also take three samples of the molten steel liquid before the furnace, after the furnace and in the casting state, and also use the German spectrometer to test to ensure that the composition of the molten steel liquid is qualified;

3. When smelting molten steel liquid, steel casting manufacturers generally use electric furnaces for smelting, the molten steel liquid must be pure, the composition must be uniform, and the principle of low temperature and fast pouring must be strictly observed when pouring to ensure the internal and external quality of castings;

4. If steel casting manufacturers want the quality of castings to be good, they must control the quality at the source, such as using high-quality raw materials and high-quality auxiliary materials, etc., when selecting raw materials and auxiliary materials, they must begin to test, and use high-end inspection equipment to conduct a strict inspection of raw materials, from the material into the factory to the finished product into the warehouse. To produce high-quality casting products, we need high-quality raw materials, and it is a truth to match a good horse with a good saddle.

5. After the steel casting is formed, the steel casting manufacturer will also adopt different heat treatment processes for the casting, and will also use the computer to control the heat treatment process, which can improve or improve the performance of the casting and increase its service life.
