hot pressured sintering Silicon Nitride ceramic machining parts
Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
Generally, in the stamping process of the workpiece, because the temperature will rise quickly during the stamping process, especially in the cold forging stamping process, it must be lubricated with lubricating oil. If lubrication is not used and the stamping is directly carried out, the finish of the workpiece will be affected. The life of the mold will be shortened, and the accuracy will be reduced. For this reason, the improvement of the mold will invest a lot of money. It is for this reason that stamping lubrication is necessary in cold forging stamping. In the case of producing dozens or hundreds of stamping parts per minute, the processes of feeding, stamping, discharging, and discharging waste are completed in a short time, and accidents of personal, equipment and quality often occur. Therefore, safe production in stamping is a very important issue. The safety measures for stamping are: ①Realize mechanization and automatic feeding and discharging of materials. ②Set up mechanical protection device to prevent hand injury. Use mold guards, automatic return devices and hand tools to feed in and out. ③Install electrical protection and power-off devices. Set up photoelectric or air curtain protection switch, two-hand or multi-hand series start switch, anti-misoperation device, etc. ④Improve the clutch and brake structure. After the danger signal is sent out, the crankshaft, connecting rod, and punch of the press can immediately stop in their original positions.
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.
