Hermetic sealing is necessary  for many electronic device and long time storagy for many goods. Hermetic sealing can be done for small item. It is very difficult for large things. And it is also difficult to do the repairing after hermetically sealed. We invented special hermetic sealing technologies for large item. These inexpensive technologies are good for high power large laser modules and other electronic devices. These are also good for long year storage of large living goods.
