With features of high temperature resistance, corrosion resistance, abrasion resistance and insulation, ceramic can work in many kinds of semiconductor production equipment with condition of high temperature, vacuum or corrosive gas for a long time. Made from high-purity alumina powder, processed by cold isostatic pressing, high temperature sintering and precision finishing, the ceramic End Effector could reach the dimension tolerance to ±0.001 mm, surface finish Ra 0.1, temperature resistance 1600℃. The ceramic End Effector with cavity can work in a high temperature of 800℃ due to unique ceramic bonding technology. Here is the characteristics of alumina ceramic with different purity.Spray Granulation → ceramic powder → Forming → Blank Sintering → Rough grinding → CNC Machining → Fine Grinding → Dimension Inspection → Cleaning PackingPlace of Origin: Hunan, China Material: Alumina Ceramic HS Code: 85471000 Supply Ability: 100 pcs per month Lead time: 3-4 weeks Package: Corrugated box, foam, carton Others: Customization service available
