Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
In addition to the hydraulic press for forming thick plates, High Precision Scribing Ceramic Substrate Sheet Thin Plate the stamping equipment usually adopts a stagnant press. Focusing on the current high-speed multi-station stagnation press, set up equipment configuration decoiling, finished product collection, transportation and other stagnation, as well as mold library and quick mold placement, and use computer French tube bundles to form a passive stamping production with high production rate. line. Under the condition of producing dozens or hundreds of stamping parts every minute, the stamping and outputting processes are completed in a short time, and personal, equipment and quality incidents often occur. Therefore, the safety of stamping is a very important issue. Wipe the surface of the outer cover with clean gauze. The High Precision Scribing Ceramic Substrate Sheet Thin Plate inspector needs to wear touch gloves to touch the surface of the stamping part along the longitudinal direction of the stamping part. This inspection method depends on the inspector's experience. If necessary, oilstone can be used to polish the detected suspicious area and verify it, but this method can be regarded as an effective quick inspection method. First wipe the surface of the outer cover with a clean gauze, and then polish with oilstone (20×20×100mm or larger), and polish with relatively small oilstone for arcuate and hard-to-reach places (for example: 8×100mm semi-circular oilstone). The High Precision Scribing Ceramic Substrate Sheet Thin Plate choice of whetstone particle size depends on the surface condition (such as roughness, galvanizing, etc.). It is recommended to use fine-grained oilstone. The direction of whetstone polishing is basically along the longitudinal direction, and it fits well on the surface of the stamping parts, and some special places can also be supplemented with horizontal polishing. Wipe the surface of the outer cover with clean gauze. Use a flexible sand net to close the surface of the stamping part and grind it to the entire surface in the longitudinal direction. Any pitting or indentation will be easily found.
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.
