ST.CERA offers ESD coating and ESD ceramic material End Effector / Handling Arm with a built-in hollow channel. We specialize in a technique that forms a vacuum air channel inside a single piece of material without using adhesive.
There is no risk of contaminant, outgassing, or particles. ST.CERA's vacuum End Effector / Handling Arm with special coating technology is electrical insulated. We can also provide ESD ceramic material that is electrical insulated without any coating.
Made from high-purity alumina powder, processed by cold isostatic pressing, high temperature sintering and precision finishing, it could reach the dimension tolerance to ±0.001 mm, surface finish Ra 0.1, temperature resistance 1600℃.
Here is the characteristics of alumina ceramic with different purity.
