The working life of precision casting parts: the unreasonable structure caused by heat treatment, excessive grain size, etc., leading to the main properties such as precision casting parts toughness, hot and cold fatigue properties, anti-wear properties such as decline, affecting the working life of precision casting parts.
The cost of manufacturing precision castings: as the intermediate process of the casting process or the final process, heat treatment caused by cracking, deformation tolerance and performance tolerance, in most cases will cast scrap, even through the patch can continue to use, but also Will increase the working hours, extend the delivery time, improve the manufacturing costs of castings.
Precision manufacturing parts precision: the uneven transformation of the organization, not complete and heat treatment of the formation of residual stress caused by excessive casting in the heat treatment after the processing, assembly and precision casting the use of the process of deformation, thereby reducing the accuracy of precision casting, or even scrapped The
Precision casting parts of the strength: improper preparation of heat treatment process, heat treatment operation is not standardized or heat treatment equipment is not complete, resulting in the intensity of the casting (hardness) to meet the design requirements.
It is the heat treatment technology and the quality of precision casting has a very close relationship, 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 strengthening technology and precision casting materials, pre-hardening technology. |
