hot pressing sintered Si4N4 Silicon Nitride insulator ring
Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
Work hardening is low. The work hardening that occurs after cold deformation will increase the deformation resistance of the material and make it difficult to continue to deform. Therefore, plates with a low hardening index are generally used. However, materials with a high hardening index have good plastic deformation stability (that is, more uniform plastic deformation) and are not prone to localized cracks Laser Scribe Film Heating Fixing Ceramic Substrate.
In actual production, process tests similar to the Laser Scribe Film Heating Fixing Ceramic Substrate stamping process are commonly used, such as drawing performance test, bulging performance test, etc. to test the stamping performance of the material to ensure the quality of the finished product and a high pass rate. The precision and structure of the mold directly affect the forming and precision of the stamping parts. Mold manufacturing cost and life are important factors that affect the cost and quality of stamping parts. Mold design and manufacturing require more time, which Laser Scribe Film Heating Fixing Ceramic Substrate extends the production preparation time for new stamping parts. Standardization of mold bases, mold bases, and guides and the development of simple molds (for small batch production), composite molds, multi-station progressive molds (for mass production), and the development of rapid mold change devices, which can reduce the workload of stamping production preparations And shorten the preparation time, so that the advanced stamping technology suitable for mass production can be reasonably applied to small batch and multi-variety production.
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.
