The material of machine tool castings is cast iron HT250-300, which has a long service life and is widely used in the processing of components such as instruments, electronics, light industry, standard parts, bearing industry, and auto parts industry, especially suitable for non-ferrous metals.

The production of machine tool castings adopts a complete resin sand production line, which uses resin sand and lost foam casting. The size is uniform and consistent, without box buckling, and the castings have no burrs or flying edges; The surface smoothness is close to casting, and the internal structure is stable. The entire production process of the machine tool bed is environmentally friendly and can eliminate or reduce casting defects such as sand holes and air pockets.

The quality management of a foundry includes two parts: casting quality control and casting methods. Is he implementing a quality system in the factory under the premise of reasonable technical requirements for castings. For the foundry industry, its characteristics are a quality system implemented in factories under the premise of standardized and reasonable casting technology requirements. For the foundry industry, this is reflected in the causes of defects. Therefore, in terms of defect control, casting quality management should prioritize preventing its occurrence and continuously research and solve various quality problems. We also need to actively conduct market research, constantly grasp the quality requirements of consumers or users, and provide serious after-sales service.
