Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
Stamping can process High Precision Scribing Ceramic Substrate Sheet Thin Plate parts with a large size range and more complex shapes, such as the second hand of a clock, as large as automobile longitudinal beams, covering parts, etc., plus the cold deformation and hardening effect of the material during stamping, the strength and stiffness of the stamping are relatively high. high. The molds used in stamping processing are generally specialized. Sometimes High Precision Scribing Ceramic Substrate Sheet Thin Plate a complex part needs several sets of molds to be processed and formed, and the mold manufacturing has high precision and high technical requirements, which is a technology-intensive product. Therefore, only when the stamping parts are produced in large batches, the advantages of stamping can be fully realized, so as to obtain better economic benefits. There are also some problems and shortcomings in stamping. It is mainly manifested in the noise and vibration generated during the stamping process, and the operator's safety accidents occur High Precision Scribing Ceramic Substrate Sheet Thin Plate from time to time. However, these problems are not entirely due to the stamping process and die itself, but mainly due to traditional stamping equipment and backward manual operations. With the advancement of science and technology, especially the development of computer technology, with the advancement of mechatronics technology, these problems will surely be resolved as soon as possible.
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.
