Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
Generally, sheet metal stamping can only form parts with the same wall thickness, and thin-walled parts with thick bottom can be obtained by thinning and stretching. The limitations of stamping and forming limit its application range. In the production of auto parts, it is often encountered with thin-walled but unequal-thickness parts. It is easy to form them by a composite plastic forming method combining stamping and cold forging. Therefore, the combination of stamping and cold forging is used. The method can expand the range of sheet metal processing. The method is to pre-form with a stamping method first, and then finally form with a cold forging method. The advantages of stamping and cold forging compound plastic forming are: First, the raw materials are easy to purchase at a low price, which can reduce production costs; second, the large forming force required for a single cold forging is reduced, which is beneficial to improve the life of the die. The microfabrication we are talking about now refers to the microparts processing technology. The definition of micro-parts usually refers to at least a dimension of less than 100μm in one direction, which has incomparable application prospects than conventional manufacturing technology. The micro robots, micro airplanes, micro satellites, satellite gyros, micro pumps, micro instruments, micro sensors, integrated circuits, etc. made with this technology have excellent applications in many fields of modern science and technology, and they can bring to many fields New expansion and breakthroughs will undoubtedly have a far-reaching impact on China's future science and technology and national defense undertakings, and the promotion of world science and technology development is also incalculable.
properties:
