The development of advanced manufacturing technology in the mold
Taiwan, in which the dispersion strengthened material point, reduce the grain boundary energy and improve grain boundary corrosion resistance, wear resistance of the surface of the mold cavity is also greatly enhanced, and some rare earth elements to improve the wear resistance reported in the literature of 1 to 4 times the other ,ugg italia, studies have found that adding mixed rare earth compounds is better than a single rare earth compounds. (5) the rare earth elements can be added coating plating, electroplating, and other deposition methods. Gan nitric acid complexes of rare earth addition of anti-oxygen passivation coating significantly improved life expectancy; rare earth elements have the role of catalytic reduction of SO, can inhibit the Ni-Cu-P/MoS brush plating coating M. Oxidation, significantly improved the performance of anti-friction coating to improve corrosion resistance ability to make the surface of the mold cavity nearly 5 times longer wear life. 4.2 Nano-surface engineering of nano surface engineering is a low-dimensional nano-materials and other materials based on non-equilibrium, by a specific processing technology, processing methods, to strengthen the solid surface, modified, super-fine processing, or to give the new surface function of systems engineering. Nano-surface engineering technology is very promising and the market potential. (1) Production of nano-composite coating. In the traditional plating solution by adding zero-dimensional or one-dimensional nano-particle powder material to form composite coatings. Die Cr-DNP for nanocomposite coating can extend the tool life, accuracy persistent, prolonged use of smooth and crack-free coatings. Nano materials can also be used for high temperature wear-resistant composite coatings. If the n-ZrO: nano-powders by adding Ni-w-B amorphous composite coatings can improve the coating in the 550-850 ~ C high-temperature oxidation resistance, corrosion resistance increased to 2 to 3 times the resistance wear resistance and hardness are significantly increased. With Co-DNP nanocomposite coating, in the 500 ~ C or more, and Ni-based, cr base, c0 composite coating compared to the surface of the high-temperature wear resistance greatly improved. In the traditional brush plating solution, by adding nano powder materials, can also be prepared nano-composite coatings with excellent performance. (2) production of nanostructured coatings. Thermal spray technology is the production of nano-structured coating an extremely competitive methods. Compared with other technologies, it has many advantages: simple process, coating and substrate selection a wide range of coating thickness range, fast deposition rate, and easy to form a composite coating and so on. Compared with traditional thermal spray coatings, nanostructured coatings in strength, toughness, corrosion resistance, wear resistance, thermal barrier, thermal fatigue, etc. have improved significantly, and a coating with the variety of performance simultaneously. 5 Conclusion mold a wide range of advanced manufacturing technology, almost most of the advanced manufacturing technology can be applied to the mold manufacturing, and constantly evolving, can not count them out in this overview. From China's national conditions, all the mold companies are high-speed CNC machining technology as soon as possible is unrealistic, because expensive equipment and technical equipment. Relatively inexpensive and appropriate for the use of special rapid manufacturing process technology,air jordan shoes cheap, it is worth considering some of the mold companies. From a different perspective, in addition to the development of advanced manufacturing technology in the mold, there are mold Reverse Engineering Technology (ReverseEirgineefin ~, mold virtual manufacturing technology fvirtualManufacturing), die flexible manufacturing technology (FMs) and mold Integrated Manufacturing Technology (CIMs), etc. . And it was suggested that the next generation of advanced manufacturing technology uses reconfigurable and scalable manufacturing equipment and systems, knowledge supply chain and independent manufacturing Island.
