Manufacturer Advantage :

We have independent intellectual property of PIBM Spontaneous Solidification system ,Professionally produce high-quality fine ceramics components.

The new technology break through the deformation and cracking problems of large-sized ceramic wet blanks in the preparation process, and the product performance is significantly optimized for the large-sized ceramic parts prepared by traditional methods.

Chemshun Ceramics' alumina ceramics sapphire lapping wafer polishing is shaped as PIBM producing process. Its an internaltional  advanced technology. PIBM sucessful solve the key problem of crack and deformation of large size alumina ceramics.PIBM technology will open another window of fine ceramics. We not only produce the high quality alumina ceramic wafer polishing plate, but also other series of large size high purity alumina ceramics such as 1200x500x20mm ceramic substrates for LCD manufacturing equipment, semiconductor delviery tracks, vacuum parts, general mechanical parts, bulletproof ceramics.
