Another development direction of heat treatment technology improvement is to combine traditional heat treatment technology with advanced surface treatment technology to increase the service life of die-casting molds. Loose defects also make the internal structure of the blank reach broken grains Plastic Injection Molded Automotive Parts in the forged state. Its basic process is as follows: first low-speed or high-speed casting of molten metal into the cavity of the mold, the mold has a movable cavity surface, it is pressurized forging with the cooling process of the molten metal, which eliminates the shrinkage of the blank. For example, the chemical heat treatment method carbonitriding, NQN (i.;   The traditional heat treatment process of die-casting mold is quenching-tempering, and later Developed surface treatment technology.Die casting mold is a method of casting liquid die forging, a process completed on a dedicated die casting die forging machine.   This type includes carburizing, nitriding, boronizing, carbonitriding, sulfur carbonitriding, etc. Due to the variety of materials that can be used as die-casting molds, the same surface treatment technology and process will produce different effects on different materials. carbonitriding-quenching-carbonitriding) composite strengthening combined with conventional quenching and tempering processes, not only obtains higher surface hardness, but also effectively hardens The layer depth increases, the hardness gradient distribution of the infiltrated layer is reasonable, the tempering stability and the corrosion resistance are improved, so that the die-casting mold has a good core performance, while the surface quality and performance are greatly improved. The carburizing process used in cold, hot work and surface strengthening of plastic molds can improve the life of the mold. Next, Shenzhen Plastic Mold Factory will explain to you, what are the common problems of die-casting molds and the treatment methods?    (1) Coating technology, including electroless plating, etc.e. The comprehensive mechanical properties of the blank have been significantly improved. When carburizing, the main process methods include solid powder carburizing, gas carburizing, vacuum carburizing, ion carburizing, and carbonitriding formed by adding nitrogen to the carburizing atmosphere.. This technology has the characteristics of fast carburization, uniform carburization, smooth carbon concentration gradient, and small workpiece deformation. On the basis of traditional technology, it proposes suitable processing technology for different mold materials to improve mold performance and increase mold life. (2) Improvement technology of traditional heat treatment process;  https://www.nbtianke.com/product/high-speed-thin-wall-injection-molding/


Surface modification technology, including surface thermal expansion treatment, surface phase change strengthening, electric spark strengthening technology, etc. Play an increasingly important role in surface treatment. Yutongda recently proposed substrate pretreatment technology for mold substrate and surface treatment technology. Among them, vacuum carburizing and ion carburizing are technologies developed in the past 20 years. It will be on the surface of the mold, especially the precision mold

The requirements of modern industry for injection molded parts not only require high precision, but also have excellent internal quality. To meet this Plastic Injection Molded Automotive Parts requirement, new injection mold technology must be developed and utilized. At present, injection molds imported from abroad are being gradually promoted in the southern coastal areas. The new technology has played a big role in improving the quality of injection molded parts. In the past few decades, the domestic plastic mold industry has developed rapidly, and the thirst and requirements for talents have become higher and higher. However, the domestic still cannot solve this thorny problem, which has become a major obstacle to the development of China’s mold industry. https://www.nbtianke.com/product/high-speed-thin-wall-injection-molding/ 
It is understood that the mold production areas in coastal areas are unable to recruit people to varying degrees. In order to attract talents, many local mold companies even recruit across regions and provinces. Three kinds of talents make up the mold industry. ’Golden collar’ personnel are proficient in mold design software and mold structure knowledge, and have accumulated a lot of practical experience in actual work. This kind of person is very suitable to serve as the technical leader or technical director of each enterprise. ’Gray-collar’ refers to the personnel who design and process molds on their posts. Such personnel account for 15% of the company’s mold technology positions. ’Blue-collar’ refers to the technical staff responsible for the specific operation and daily maintenance of the mold in the production position, accounting for 75% of the corporate positions, which is currently the most in demand. This has become one of the major obstacles to the domestic mold industry. Strengthening the training of professional talents is an urgent matter for the mold industry.   
With the rapid development of the injection mold industry, a new model of injection mold manufacturing based on the information age. The production efficiency of the injection mold industry has been greatly improved, and the impact on the manufacturing industry has a milestone impact. Because of the organic combination of product information and manufacturing information related to injection mold manufacturing activities, traditional manufacturing has developed rapidly. In the information age, this advantage has been extremely well played and embodied. The modern manufacturing process can be regarded as the value-added process of the amount of information contained in raw materials, and the drive of industrial information flow will become the mainstream of the manufacturing industry.   Because injection molded products are widely used in daily life, mold technology has become an important indicator of a country’s product manufacturing level.   In recent years, my country’s injection molds have developed rapidly in terms of quality and quantity. However, compared with foreign advanced technologies, the technical standards of most Chinese enterprises still need to be improved. At present, compared with the advanced technology level of foreign countries, China’s injection mold industry has the following problems: The contradiction between supply and demand is difficult to solve in the short term: domestic injection mold domestic market satisfaction rate has been less than 74%, of which the satisfaction rate of large, precise and long-life molds is lower. .
At present, the transfer of molds from industrially developed countries to China is accelerating, and international purchases are increasing. The market demand is strong, production development is still difficult to keep up for a while, and the situation of short supply will continue for some time. Unbalanced industrial development: Although the products of individual companies have reached or are close to the international advanced level, overall, the accuracy, production cycle, and service life of molds are still far behind foreign countries. The overall level of industrial development is relatively low. low.
