Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
For example, micro-robots can perform complex operations such as optical fiber lead, bonding, docking, and inspection of small pipes and circuits. It can also perform integrated chip production and assembly. It is not difficult to see the attractive charm of micro-processing. Developed industrial countries attach great importance to the research and development of microfabrication, and have invested a lot of manpower, material resources, and financial resources. Some well-known universities and companies with vision have also joined this rank. Our country has also done a lot of research work in this area. It is reasonable to believe that in the 21st century, microfabrication will definitely bring huge changes and profound impacts to the entire world like microelectronics technology. For the mold industry, due to the miniaturization of stamping parts and the continuous improvement of precision requirements, higher requirements are put forward for mold technology. The reason is that the forming of micro parts is much more difficult than traditional parts. The reasons are: the smaller the part, the rapid increase in the surface area to volume ratio; the adhesion between the workpiece and the tool, surface tension, etc., significantly increase; the influence of grain size Obviously, it is no longer an isotropic uniform continuum; it is relatively difficult to store lubricant on the surface of the workpiece. An important aspect of micro punching is punching small holes. For example, there are many small holes that need to be punched in micro-machines and micro-instruments. Therefore, the study of small hole punching should be an extremely important issue in micro punching. The research on punching small holes focuses on: first, how to reduce the size of the punch; second, how to increase the strength and rigidity of the micro punch (in addition to the materials and processing technology involved in this aspect, the most commonly used is to increase the micro Guiding and protection of punches, etc.).
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
