PLC vacuum quartz tube brazing furnace
It’s a multi-functional vacuum equipment mainly used for capsulation of ceramic and glass vacuum switching tube in vacuum electronic tube industry. It features high vacuum, high pumping speed and low oil return(barely oil return). It can also be used for vacuum brazing or heat treatment of stainless steel that requires high vacuum and environment friendly.
