sintered silicon nitride ceramic machinery parts
Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
Stamping is mainly classified by process, which can be divided into two categories: separation process and forming process. The separation process is also Laser Drilling Electronic Ceramic Substrate Strap Board called punching, and its purpose is to separate the stamping part from the sheet along a certain contour line while ensuring the quality requirements of the separated section. The purpose of the forming process Zirconia Ceramic Rings is to make the sheet metal Ceramic Disc plastically deform without breaking the billet to make a workpiece of the required shape and size. In actual production, multiple processes are often applied to one workpiece. Blanking, bending, shearing, stretching, bulging, spinning, and correction are the main stamping processes. (Blanking)
It is a basic stamping process that uses molds Laser Drilling Electronic Ceramic Substrate Strap Board to separate materials. It can be directly made into flat parts or prepare blanks for other stamping processes such as bending, drawing, and forming. It can also be cut and trimmed on the formed stamping parts. ...에 Blanking is widely used in industries such as automobiles, household appliances, electronics, instrumentation, machinery, railways, communications, chemicals, light industry, textiles, and aerospace. The blanking process accounts for about 50% to 60% of the White Zirconia Ceramic entire stamping process. Bending: A plastic forming method of bending metal sheets, pipe fittings and profiles into a certain angle, curvature and shape. Bending is one of the main processes widely used in the production of stamping parts. The bending of metal materials is Laser Drilling Electronic Ceramic Substrate Strap Board essentially an elasto-plastic deformation process. After unloading, the workpiece will produce directional elastic recovery deformation, which is called springback. Springback affects the accuracy of the workpiece and is the key technology that must be considered in the bending process.
