Silicon Nitride Ceramic:
The die used for stamping is called stamping die, or die for short. The die is a special tool for batch processing of materials (metal or non-metal) into the required stamping parts. Punching dies are very important in stamping. Without a die that meets the requirements, mass stamping production will be difficult; without advanced dies, advanced stamping processes cannot be realized. The stamping process, die, stamping equipment and stamping materials constitute the three elements of stamping processing. Only when they are combined can stamping parts be High Precision Ceramic Network Resistor Substrate Plate obtained.
Compared with castings and forgings, stamping parts are thin, uniform, light and strong. Stamping can produce workpieces with ribs, ribs, undulations or flanges that are difficult to manufacture by other methods to improve their rigidity. Due to the use of precision molds, the precision of the workpiece can reach the micron level, and the repeatability is high, the specifications are consistent, and holes, bosses, etc. can be punched out. Cold stamping parts are generally no longer processed by cutting, or only a small amount of cutting processing is required. The precision and surface condition of hot stamping parts are lower than cold stamping parts, but still better than castings and forgings, and the cutting amount is less.
Stamping is an efficient production method. Using compound dies, especially multi-station progressive dies, multiple stamping processes can be completed on one press (single-station or High Precision Ceramic Network Resistor Substrate Plate multi-station) to realize strip uncoiling and straightening. Fully automatic production from flattening, blanking to forming and finishing. High production efficiency, good working conditions, low production cost, generally hundreds of pieces per minute can be produced. Compared with other methods of mechanical processing and plastic processing, stamping processing has many unique advantages in both technical and economic aspects.
point.
The stamping process High Precision Ceramic Network Resistor Substrate Plate has high production efficiency, convenient operation, and easy realization of mechanization and automation. This is because stamping relies on punching dies and stamping equipment to complete the processing. The number of strokes of ordinary presses can reach dozens of times per minute, and the high-speed pressure can reach hundreds or even thousands of times per minute. May get a punch.
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.
