In general, there are many factors that affect the dimensional accuracy of castings, such as the structure, shape, and size of the casting itself, the quality of foam, the impact of paint coating, the influence of modeling and pouring during the casting process, and so on.
In the entire valve casting process, the pouring process is one of the most important links. The four factors of pouring system, pouring speed, pouring temperature, and pouring process are the key processes to improve the quality of castings. Only by continuous improvement and continuous improvement can castings be made. Castings with high precision and high quality.
Paint coating also has a great influence on the accuracy of castings. Paint performance and coating thickness can affect the size of the pattern, thereby affecting the dimensional accuracy of the castings. Therefore, in casting, the coating should have good performance and sufficient strength, and the coating should be coated. The operation process should be reasonable.
After analyzing the factors that affect the dimensional accuracy of valve castings, companies should start with these factors and break each one to achieve the purpose of improving the accuracy of castings.
