Process flow and equipment list

Step1: Confirm Granulation Step2: Forming Cold Isostatic Pressing (CIP) Isostatic pressing technology is an advanced equipment for ultra-high pressure hydraulics, which is formed by using the product under uniform ultra-high pressure conditions in a closed high pressure vessel. According to the temperature during forming and consolidation, isostatic pressing technology is divided into three different types: cold isostatic pressing, hot isostatic pressing and hot isostatic pressing. Step3: Sintering Special Sintering Sintering Step4: Inspection Quality Control, QC Step5: Processing Grinding CNC Lathe CNC Mill CNC Mill CNC Mill Centerless grinding Centerless grinding Round grinding Quality Control, QC Quality Control, QC Materials Step6: Shipping Shipping Shipping Shipping Shipping Shipping

National Day holiday announcement

Porous Ceramic

LONGYI started the development of Porous Ceramic Chuck, Disco dicing chuck, wafer dicing chuck table, wafer dicing stage and floating stage in 2013. Its main customers are semiconductors, solar energy and LCD. For porous ceramics, the microstructure is made up of small crystals called grains. In general, the smaller the grain size, the stronger and denser is the ceramic material. The wide variety of applications for porous ceramic materials results from their unique properties. In many respects, these properties cannot be achieved by other materials. Application: Vacuum Nozzle Vacuum Chuck Air Bearing Work Holding Air floating stage III.
