CoorsTek manufactures very large sized quartz glass tubes and chambers utilizing its superior welding technology and unique equipment. In particular, we are contributing to realize a "Clean Process" in the annealing process for very large substrates, such as FPD (Flat Panel Displays) like LCDs, and Solar Batteries. Also, we support new designs of very large sized quartz glass products based our production know-how accumulated over the years, experience, as well as our simulation technology.
From the capability point of view, it is possible to manufacture tubes larger than 2000mm in size.

*It is also possible to manufacture square type tubes, too.
