The SLG glass to metal sealing mesh belt furnace provides a controlled nitrogen atmosphere platform for the sealing of glass to metal joints in electronic components, sensors, diodes, rectifiers and hermetic packages. Operating at a working temperature of 800C, the furnace melts and fuses the sealing glass to the metal housing while the nitrogen atmosphere prevents oxidation of the leads and the glass, producing gas tight, electrically insulating seals.
