electronic black silicon nitride machining ceramic disk disc plate
Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
Except for forming thick plates with hydraulic presses, mechanical presses are generally used. With modern high-speed multi-station mechanical press as the center, it is equipped with uncoiling, leveling, finished product collection, conveying and other machinery, as well as a mold library and a quick mold change device, and is controlled Silicon Nitride Parts by a computer program to form a high-productivity automatic stamping production line. Generally, Stamping Ceramic Substrate Electronic Base Board 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 you do not use lubrication and stamping directly, in addition to the workpiece finish is 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 Stamping Ceramic Substrate Electronic Base Board 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, Silicon Nitride equipment and quality often occur. Therefore, safe production in stamping is a Stamping Ceramic Substrate Electronic Base Board very important issue. The safety measures for stamping are to realize mechanization and automatic feeding and discharging of materials. Set up mechanical protection device to prevent hand injury. Use mold guards, automatic return devices and hand tools to feed in and out. Set up 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. Improve 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.
