Offers aluminum spacer bar production line is advanced technology, superior performance, and high cost performance, production speed more 120 mmin. Aluminum spacer has been widely used in energy-saving window and door. Our chopped wave type high frequency power supply has advantage in energy-saving and reliability, some company has adopted it.Process flow: uncoiler loading forming high frequency welding scraper sizing straightening flying saw lay off table.Composition of production line: uncoiler, tube mill, solid state high frequency welder, straightening and shaping machine, flying saw.High frequency welder use chopped wave type high frequency power supply, welding speed 100-120 mmin.The requirement of aluminum spacer:wall thickness: wall thickness must between 0.2-0.35mm, the maximum deviation is0.025mm.Curvature: spacer should no hard bending and side bending (beside bending radian of free droop).Appearance: surface is flat and smooth, no bump, pore uniformity and orderliness.
