Aluminum Spacer Bar Production Line is advanced technology, superior performance, and high cost performance, production speed more 120 M/Min. 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 M/Min.

The requirement of aluminum spacer:

Wall thickness: Wall thickness must between 0.2-0.35mm, the maximum deviation is±0.025mm.

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.
