Copper as main die casting alloy has the characteristic of high hard ness, high corrosion resistance, higest mechanical properties of alloys die cast, excellent wear resistance and excellent dimensional stability.
Based on the above characteristic, brass Die Casting Parts are generally used in the industries of electronics, shipbuilding and chemical industries.

This tremendous achievement has completely broken the blockade and embargo against China in the field of electric vibration technology for decades, changed the pattern of the international vibration industry, and advanced China's vibration technology to the advanced level of the country, making China dying. The vibration industry "dry woods and springs" has made the Chinese people proud and add glory to the Chinese nation.
The vibration test bench is a main means of mechanical environment test equipment. It is of great significance for the research and production of cutting-edge industries such as missiles, satellites, airplanes, ships, automobiles and electronics. It belongs to the current world regulated product catalogue and has been used by the United States and Britain for a long time. Major Western countries such as Japan monopolize.
For a long time, the research and manufacturing level of China's vibration test system has lagged far behind the international. Eleven years ago, the only three vibration table production units in China had their own independent research and development capabilities, and only produced small vibration tables below 2 tons of thrust. The technology was introduced from abroad and the price was high. More than 2 tons of foreign products are strictly sealed and embargoed by China. This has seriously affected the development of China's national defense science and technology industry.
In the early days of the venture, the private high-tech enterprise Suzhou Dongling Co., Ltd. established the goal of competing with the international ace companies that developed the vibration table of the United States ling electronics company and the British ling power company. In the past eleven years, Wang Xiaozhong, the general manager of Dongling Company (ie, Dongfang Zhiling), has made a heart, and has led more than 200 Dongling people to embark on the road of independent innovation. Multi-disciplinary, multi-disciplinary personnel, work together, perseverance, perseverance, overcome one problem after another. It has successively developed ten series and nearly one hundred vibration tables of 5 tons, 6 tons, 10 tons, 12 tons, 16 tons and 18 tons, among which more than 30 products are in the world's leading level. At present, they have been sold to the United States and Britain. Japan, Germany, Russia and other more than 20 countries and regions. And successfully participated in the vibration test of Shenzhou 5 and 6 manned spacecraft. In the national defense bidding of the Beijing Satellite Environmental Testing Center, Dongling Company met with the “Ling†companies of the United States and Britain, and “Mitsubishi competes and flies to Donglingâ€. This research and development process, which was the birth of 35 tons, accumulated rich experience and created favorable conditions, which led to the successful completion of the development of 35 tons.
The moving coil is the most critical component of the electric vibrating table. The dynamic characteristics of the vibrating table directly affect the level of the first-order axial resonant frequency of the vibrating table active system, which affects the upper limit of the operating frequency of the vibrating table and a series of technical indicators. High and low. The higher the resonance frequency, the higher the upper limit of the frequency of use, and the more experiments that can be performed, the more favorable it is to the user. Therefore, they will raise the resonant frequency as the top priority of technological innovation and research. They optimized the structure of the moving coil skeleton, made the quality and rigidity of the moving coil structure get reasonable distribution and coordinated utilization, and innovated the design of the force-transmitting gusset of the table top, effectively increasing the rigidity of the moving coil skeleton. Therefore, the core technical index of resonant frequency is far ahead of the advanced level of similar products in the world.
They innovated the winding structure and winding process of the drive coil to improve the cooling effect. The cooling effect of the drive coil windings is not good, which is a common problem for the world's electric vibration table manufacturers. They have boldly innovated and applied a new parallel cooling structure for the traditional series cooling structure with poor cooling effect in the world. The driving coil windings are taken out of the cooling water pipe from the middle, so that the original single cooling becomes two-way cooling. The cooling effect of the drive coil winding is doubled, thereby overcoming the difficulty of insufficient cooling of the drive coil winding. At the same time, they also carried out a series of other innovations and transformations in design and process, which overcome the electrochemical corrosion of the coil nozzle under larger current and voltage conditions, the severe heating of the moving coil drive wire and the insufficient cooling of the inner short circuit ring. Many technical difficulties such as burnout have ensured the smooth production of the 35-ton vibrating table.
The advent of 35 tons has aroused great concern and shock from international counterparts.
