ZRC-8 gas quenching vacuum brazing furnaces for aluminum
¡Â
Model ZRC-8 is mainly applied in brazing and gas quenching of radar antennas and channel wave guides, especially for the complex thin units made out for wrought aluminum alloy L6061, L6063, LF21 and LD31. Vacuum pumps, vacuum meters, and computer control system of model ZRC-8 are imported from leading suppliers of European and American. Model ZRC-8 features as: construction of advanced technology, perfect function, and reliable working performance.
