The working life of precision castings: the organization structure caused by heat treatment is unreasonable, the grain size exceeds the standard, leading to the main properties such as toughness of castings, hot and cold fatigue properties, wear resistance and so on, affecting the working life of precision casting parts.
The cost of manufacturing precision castings: As the intermediate or final step in the manufacturing process of precision castings, cracking, distortion and poor performance are caused by heat treatment. In most cases, castings are discarded and can be used even if they are repaired. Will increase the working hours, extended delivery time, increase the cost of manufacturing castings.
Precision casting precision manufacturing: organizational transformation is not uniform, incomplete heat treatment and the formation of residual stress caused by excessive casting after the heat treatment, assembly and precision casting process of deformation, thereby reducing the accuracy of precision casting, or even scrap .
Precision casting parts strength: heat treatment process is not properly developed, heat treatment operation is not standardized or heat treatment equipment is not good, resulting in the strength of the castings to be processed (hardness) can not meet the design requirements.
It is heat treatment technology and the quality of precision casting closely related, making these two technologies in the process of modernization, mutual promotion and common improvement. In recent years, the international precision casting heat treatment technology is the rapid development of the field of vacuum heat treatment technology, precision casting parts of the surface hardening technology and precision casting material pre-hardening technology.
