Die steel is one of the important material production mold, under the mold industry to promote the development of die steel industry is relatively rapid, demand is also increasing, especially in high-grade plastic mold steel, mold steel demand will continue to increase.It is understood that the mold belongs to consumables, large amount. According to the research report, the automotive industry for more than 90% of the parts from the mold forming, while using cold and hot working die steel, plastic, die per million cars consume 0.12 tons of household appliance industry; 80% parts by molding, with the largest amount of plastic mold steel.The next 5 years, China's die steel industry will have greater room for development, especially in high-end product areas. The future, domestic high-end mold steel will gradually import substitution. For China's large iron and steel enterprises, the future development of mold steel industry to do research on the following aspects: first, strengthening the basic theory research, improving the quality and performance of die steel; secondly, the implementation of diverse varieties of mold steel specifications, fine materials and products; again, accelerate the application of information technology to improve the row production specialization; at the same time, we should focus on the development of plastic mold steel, in the high-end route, establish brand mold steel and steel store sales model innovation, and constantly promote the development of domestic die steel industry.
China's mold industry, a long time ago is based on low-end products as the main, started late, but with the gradual transformation, new opportunities have emerged in the industry. Mold industry is the main technological innovation, technical upgrading is necessary, this is the industry's rapid development and market demand in the most important conditions.It is reported that the Chinese market is currently a large number of high-grade mold demand, especially home appliances, automobiles, plastics industry. According to the mold alliance network understanding, "12th Five-Year" period, the overall trend of the mold market steady upward, but requires domestic mold must be in terms of quality, delivery and so on to meet the needs of users.In the international market, developed countries are transferring to developing countries, especially Southeast Asian countries, because of the increase in labor costs. Its domestic production of high, refined mold based, artificial labor input large amount of mold, relying on imports to solve. Therefore, the middle and lower mold market potential is very huge. As long as the quality of China's mold can be improved, the delivery time can be guaranteed, and the export prospect of the mold is very optimistic. There is a great demand for standard parts of moulds, but only a small quantity of exports are available in china.In recent years, China imports nearly 1 billion U. s.dollars a year mold, most of the precision, large, complex and long-life mold. From the point of view of reducing imports, such high-grade mold, hardware tools in the market share will gradually increase. The future, China's mold and CNC tool industry will be the biggest in the world.From the technical development trend of machinery manufacturing industry, the proportion of efficient CNC machine tools in China's factories will increase year by year, and the demand for highly efficient and advanced cutting tools will increase rapidly. In addition, due to the increase in labor costs, the price advantage of medium and low cutting tools will gradually be lost. For the advanced CNC machine tool increases the demand for this situation, China tool industry must change the idea, to develop efficient and advanced cutting tool production, pay attention to sales at the same time, we should pay more attention to customer service service, strive to innovate more market share.
For the development of the industry, the market is the most important, the better development of the market in order to reflect the most direct trend of the industry's good and bad. At present, with the improvement of all aspects of the mold industry and the improvement of Chinese auto parts have been on the right track, and toward a higher direction, recently, experts from the Department learned that the current auto parts mold problems mainly in the following aspects.Development of intelligent auto parts mold industry to achieve rapid developmentAlthough the market situation is not optimistic, but there is still a turn for the better. Since the beginning of the global financial crisis, according to the fact that the key enterprises in the global auto parts mold industry are higher than the general enterprises, the China Association revised the relevant assessment rules. Improved evaluation criteria.It is reported that with the continuous development of China's low-cost human resources difficult to continue and the level of science and technology is an important development direction of automation and intelligent manufacturing is bound to become the modern manufacturing industry, intelligent auto parts mold also will be rapid development. The production of products with intelligent auto parts moulds can further improve product quality and production efficiency, make more materials, and realize automatic production and green manufacturing.Therefore, intelligent auto parts mold while the current total is not much, but it represents the development direction of the new auto parts mold technology, will play an increasingly important role in the transformation of industry structure adjustment and development mode. Intelligent auto parts mold development, is bound to promote the rapid ascension of the entire auto mould industry level play a leading role, so strong, in the development of the industry to give priority to the development of intelligent auto parts mold is necessary.The development of intelligent auto parts mold, not only is a new requirement of manufacturing of auto parts mold industry, auto parts mold industry at the same time it is also the further development of the driving force, therefore, it will become the future direction of auto parts mold industry.If you want to get the biggest development that produce products must meet the following three points in auto parts mold industry: do, do fine, and stronger, this is not just for auto parts mold industry enterprises, the highest purpose is also applicable to various industries in the production of its products to be followed.
The use of 45# in the whole mold platen steel forged, through heating and air hammer hammer its hardness can reach above 30HRC hardness. Then use the universal milling machine to process the flat and long groove to achieve 3.2 surface finish. And the degree of parallelism of the platen, flatness, all errors are not greater than 0.02MM. After heat treatment, the quenching reaches the JB requirement of 35HRC to 40HRC. Finally, surface blackening or bluing, not rust spots to achieve.The die pressure includes U type press plate, parallel platen, mechanical platen, T type groove plate, spring steel parallel plate, bird shaped plate, round plate, trimming plate, wide head plate, straight platen, etc..An auxiliary fixture used in mold processing, the main function of which is to make the machined parts not vibrate or move during the process. To ensure the accuracy of the workpiece and the smooth finish. Therefore, the quality of mold platen directly affects the quality of mold products. Therefore, the die platen plays an important role in the mold manufacturing process. The mould platen has the advantages of high strength, small size and flexible operation.
Plastic is a lighter material with relative density between 0.90 - 2.2. Obviously, can plastics float onto the surface of the water? Especially for foamed plastics, because of the micropores, the texture is lighter and the relative density is only 0.01. This property allows plastics to be used in products that require less weight.Most plastics have good corrosion resistance to acids, alkalis and other chemicals. Especially, commonly known as king of plastic polytetrafluoroethylene (F4), the chemical stability is even better than gold, put in the "aqua" for more than ten hours do not deteriorate. Because of its excellent chemical stability, F4 is an ideal corrosion resistant material. For example, F4 can be used as a material for conveying corrosive and viscous liquid pipes.Ordinary plastics are bad conductors of electricity. Their surface resistance and volume resistance are very large. They can be expressed in figures of 109 and 1018 ohms. The breakdown voltage is large and the dielectric loss tangent is very small. Therefore, plastics are widely used in the electronic and mechanical industries. Such as plastic insulated control cables.Generally speaking, the thermal conductivity of plastic is relatively low, equivalent to the steel 1/75 - 1/225, foam microcellularIt contains gas, which is better for heat insulation, sound insulation and shock resistance. For example, the thermal conductivity of polyvinyl chloride (PVC) is only 1/357 of steel and 1/1250 of aluminum. In the heat insulating ability, single glass window than single glass windows 40%, double glass high 50%. After the plastic form and the hollow glass are combined, the utility model can be used in the house, the office building, the sickroom and the guesthouse. The utility model has the advantages of saving the heating in winter and saving the air conditioning expenses in summer.Some plastic as hard as stone, steel, such as paper, some soft leather; from the plastic hardness, tensile strength, elongation and impact strength and other mechanical properties, wide distribution, great use of choice. Because of the small proportion and high strength of plastics, they have higher specific strength. Compared with other materials, plastics also have obvious disadvantages, such as easy combustion, poor stiffness, high metal resistance, poor aging resistance, and non thermal resistance.
