refractory Silicon Nitride ceramic bush bushing sleeve
Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
Wipe the surface of the outer cover with clean gauze. Then Ceramic Substrate Hybrid Integrated Circuit Sheet use a clean brush to apply oil evenly to the entire outer surface of the stamping in the same direction. Put the oiled stamping parts under strong light for inspection. It is recommended that the stamping parts be erected on the car body. This method can easily find tiny pits, pits, and ripples on the stamping parts. Visual inspection is mainly used to find abnormal appearance and macro defects of stamping parts. Put the stamping parts into the inspection tool and inspect the stamping parts according to the operating requirements of the inspection tool manual. In actual production, process tests similar to the stamping process are commonly used, such as deep drawing performance test, bulging performance test, etc. to test the stamping performance of Ceramic Substrate Hybrid Integrated Circuit Sheet 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 extends the production preparation time for new stamping parts. Standardization of mold bases, mold bases, and guides and development of Ceramic Substrate Hybrid Integrated Circuit Sheet 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 preparation work for stamping production And shortening the preparation time can make it suitable for reducing the amount of preparation for stamping production and shortening 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.
