Advanced Technology

Complete once-for-all sealing furnace is designed and manufactured by international well-known professional device company, being the core device to manufacture the VI in our company, its advantages are followed:
a. Adopt the vacuum system with fully oil free, mean while, during the process of welding the VI, it is not polluted by oil steam.
b. Adopt two large-size turbo molecular pumps to provide the quick pumping speed and high ultimate vacuum.
c. Widely effective volume areas and evenly distribution of the temperature are appropriate for complete once-for-all sealing of VI.
d. It is controlled by computer and operated through no manned intelligent, furthermore, its technical curve is accuracy, which is very helpful for products' evenness.
Automatically plate hydrogen oven is designed and manufactured by international well-known professional device company, being the key device of ceramic metallization technical and exerting direct and great effects on ceramic metallization fabrication quality of insulated ceramic shell in the VI, its advantages are followed:
a. The device is controlled by computer, thereby its accuracy for control temperature is high and running is steady and reliable.
b. Automatic, consistent, reliable and cyclic feeding and outgoing products is useful for high rate of finished products in terms of ceramic metallization, good conformity, reasonable distribution grad of temperature, small stressed main body of ceramic shell and metallization coating and glaze is stressed light and being reliable.
c. The coat of metallization ceramic shell is artistic and smooth as well as tightness; outstanding air tightness of metallization coating and high strength, at the same time, it' s minimum intensity of tension reaching 130Mpa.
