Molds are considered to be precise when they meet all eight of the performance requirements outlined for the process. The high-precision tolerance of electronic stamping parts is 0.01mm at the Heju Precision Metal Stamping Factory. The production of precision molds typically involves going through a number of processes such as forging, cutting, and heat treatment.

Forgeability is characterized by a low resistance to hot forging deformation, good plasticity, a wide forging temperature range, a low tendency toward forging cracking, cold cracking, and the precipitation of network carbides, and a wide forging temperature range. Forgeability also includes a low tendency toward forging cracking, cold cracking, and the precipitation of network carbides.

It is possible to obtain a deep hardened layer after hardenability quenching, and it is possible to harden it by making use of a mild quenching medium. Both of these outcomes are possible. In addition, there is a significantly reduced possibility of quenching deformation and cracking after the hardenability quenching process. Conventional quenching has a low susceptibility to cracking, is insensitive to quenching temperature CNC machining services and workpiece shape, has a relatively small loss of grindable grinding wheel, allows for a large amount of grinding without hitting a burn limit, is insensitive to the quality of the grinding wheel and cooling conditions, and is not susceptible to grinding cracks or abrasion. The following list gives an overview of the four characteristics that set precision molds apart from other types of molds. After being plastically denaturated inside the mold cavity, the wear-resistant blank will flow and slide along the surface of the cavity. This will allow the wear-resistant blank to produce the desired part. Because of this, there is a great deal of friction that develops between the surface of the cavity and the blank, which ultimately results in the failure of the mold due to wear. In general, the wear and tear on the mold parts is decreased, and the wear resistance is improved proportionally, when the mold parts have a higher level of hardness.

The quantity of carbides, their shape, size, and distribution, in addition to the type of carbides that are present in the material, are all factors that influence the wear resistance of the material. Fatigue Fracture PerformanceIn the course of the working process of the mold, when subjected to the continuous action of cyclic stress for an extended period of time, it frequently results in fatigue fracture.

The performance of the mold in terms of fatigue fracture is primarily determined by its strength, toughness, and hardness, in addition to the amount of inclusions that are present in the material. Case in point: Case in point: Case in point: CasThe mold's hardness and strength will decrease as a result of improvements made to the performance of the mold when it is subjected to high temperatures. Because of this, the mold will wear out faster than normal or the plastic will deform. Because of this, the components that go into precision metal molds need to have a high level of resistance to tempering in order to ensure that the mold maintains a high level of hardness and strength while it is being used.

Grinding is a process that is used during the manufacturing of precision mold parts.

Mold parts or components that are reinstalled after the mold has been damaged are examples of accessories for molds. Molds can also be damaged during the manufacturing process. The term "mold accessories" can also be used to refer to the various aluminum die casting parts and components that are required in order to put together the mold. The quality of the process parts has an immediate and decisive bearing on the quality of the molded products. There is a correlation between the process of precision machining and the durability of both the precision mold as well as the product that is formed.

Controlling a large number of technical parameters is required in order to process precision mold parts using grinding. These parameters include deformation, internal stress, shape tolerance, and dimensional accuracy of the parts. The operation is more difficult when it is applied to a particular production practice; however, as a result of Dongguan Shili and their 15 years of experience in precision machining, we are able to summarize and analyze the methods that can be used as references:1. The vast majority of companies that specialize in the processing of precision mold parts place a high level of importance on the control of the processing process as a means of enhancing both the processing effect and the economy. 

2. In the grinding stage of the processing of precision mold parts, the three most common types of machine tools that are utilized are surface grinders, internal and external cylindrical grinders, and tool forming grinding machines. Surface grinders are the most common type of grinder used. It is essential to exercise stringent control over the occurrence of grinding deformations and grinding cracks, including microscopic cracks on the surface of the workpiece, during the finishing grinding process. If this is not done, the imperfections will gradually become visible in the work that comes after it.

When selecting components, look for those that have a machining allowance of cooling liquid medium that is as close to 0 as it is possible to get. After being passivated, the grinding wheel will slide, score, and squeeze on the surface of the workpiece. On the surface of the workpiece, this will cause burns, microscopic cracks or grooves, all of which will have a significant impact on how the workpiece is utilized in the future. decrease in efficiency in useIt is challenging to process long plate parts that are thin due to the fact that they are so thin. A surface grinder is used for the vast majority of the work that is done on disc and plate parts. The piece of work was deformed after grinding, but it quickly returned to its original shape when it was subjected to the original stress. As a direct consequence of the deformation recovery, the flatness cannot live up to the expectations placed upon it by the processing of precision mold parts. The quantity should err on the side of caution, and the datum plane can be completed by making multiple passes.
