There are many different subcategories that can be subdivided into the method of vacuum quenching. Each of these subcategories is named after a specific kind of cooling medium.

When it comes to the vacuum heat treatment of die-casting molds, the processes of vacuum oil-cooled quenching, vacuum air-cooled quenching, and vacuum tempering are the most common methods that are used. In addition, vacuum oil-cooled quenching and vacuum air-cooled quenching are also used. During the quenching process of molds, the primary types of cooling methods that are utilized the majority of the time are oil cooling, air cooling, and a combination of the two. Intelligent heat treatment of die-casting molds has become necessary as a result of the small batch and multi-variety characteristics of die-casting mold production, as well as the high requirements for heat treatment performance, and the characteristics of not allowing waste products to accumulate. These factors combined make it necessary for die-casting molds to undergo heat treatment. The distribution of temperature and stress in a die-casting mold as simulated by a computer while the mold is being heated up for the process of die-casting. The heating and cooling processes for die-casting molds are modeled and simulated here. The simulation of the quenching process on a computer, as well as the development of automatic control technology for use in heat treatment equipment. The temperature field, the phase change process, and the distribution of the stress field were all simulated on the computer. This is due to the fact that the matrix needs to be robust enough to withstand the die-casting mold as well as strong enough to support the die-casting mold. In recent years, there has been a rapid advancement in this field of study due to die casting services the fact that surface treatment technology can frequently achieve twice the result with half the effort. This has been one of the primary reasons for the acceleration of advancement in this field.

Surface treatment technology of die-casting molds is a systematic project that aims to change the morphology, chemical composition, structure, and stress state of the surface of die-casting molds in order to obtain the required surface properties. Surface treatment technology of die-casting molds is also known as die-casting mold surface treatment technology. This can be achieved through the application of a surface coating, the modification of the surface, or the utilization of composite treatment technology. The mechanical method, the chemical method, the physical method, and the physical chemical method are the subcategories that fall under this category.

The term "nitriding" refers to a process that encompasses a wide variety of procedures, some of which are gas nitriding, ion nitriding, liquid nitriding, and others. The term "nitriding" refers to a process that encompasses a wide range of procedures. Nitriding was the first method of surface hardening to be developed, and it is also the method that has seen the most widespread application. Because of these processes, it is possible to replace materials of a higher grade with materials of a lower level. The technology of hardened film deposition is currently further along in its development when compared to both CVD and PVD. The bonding strength of the surface of the film workpiece has been the focus of a number of recent research and development efforts directed toward improving CVD and PVD technologies. These efforts were carried out in an effort to improve CVD and PVD technologies. This action was carried out in order to fulfill die casting aluminum the prerequisites that had been stipulated by the industry. This is due to the fact that the technology of hardened film deposition has a relatively long service life and requires a relatively low temperature during the process of deposition. If the proposal to establish a heat treatment center is accepted and carried out in accordance with the plans, then there will be a significant reduction in the cost of coating hardened film. If the technology that is utilized in the production of die-casting molds were to be implemented into the production of molds in my country, there would be a significant improvement in the quality of the molds that are manufactured there. The development of pre-hardening technology for mold materials has picked up speed as a direct result of the enhancements that have been made to the effectiveness of the processing machine tools and cutting tools.

The manufacturers of mold materials are the ones who are primarily responsible for developing and implementing the pre-hardening technology that is used for mold materials. The entities most directly responsible for this are those that manufacture mold materials. It is possible to mass produce pre-hardened modules of a quality that is consistent throughout the run of the production by modifying the chemical composition of the steel and outfitting production facilities with the appropriate heat treatment equipment. This will allow for mass production of pre-hardened modules. At the present time, neither of these factors is adequate to meet the requirements of the domestic mold manufacturing industry. The use of mold materials that have already undergone the pre-hardening process can simplify the mold manufacturing process, reduce the amount of time spent on the mold manufacturing cycle, and improve the level of accuracy achieved by the process.
