Alumina Ceramic Suction Cup is a high-performance vacuum adsorption component designed for high-temperature, strong corrosion and high-wear industrial scenarios. It is widely used in semiconductor manufacturing, glass hot bending, laser processing and other fields. Compared with traditional rubber or polymer suction cups, its core advantage lies in the use of high-purity (≥99%) alumina ceramic material, which gives the product high temperature resistance (long-term use at 500°C), super wear resistance (Mohs hardness level 9) and chemical corrosion resistance. This feature enables it to perform excellently in tasks such as transporting high-temperature glass substrates, fixing wafer etching processes, and transferring workpieces in corrosive environments, avoiding the adsorption failure problem caused by softening, wear or corrosion of ordinary suction cups. In addition, its extremely low thermal expansion coefficient (7.2×10⁻⁶/K) ensures dimensional stability under sudden temperature changes, significantly improving adsorption accuracy and life.
