Panel Welder

ZZ's automated panel welding machine will give high productivity and quality towards the manufacturing of membrane panels.

The standard panel welder is designed to a width of 1600mm operating with 4 welding torches utilising submerged arc welding technology, we may however custom built to the customer's requirement (owing to technical limitations). Our experiences span from panel welders with varying widths, welding heads running purely SAW or MIG/MAG or both.

ZZ continues today to innovate and adopt newer technology in achieving user friendliness with the introduction of touch screen panels. The panel welder will greatly increase output and reduce overhead with just 2 operators.

The panel welder may also be designed to run on a gantry system.

Fin-bar preparation is critical in ensuring an accurate panel dimension as well as welding quality, this equipment de-scales, straightens, calibrates the width, bevels and cuts the fin-bar to the correct size.

We manufacture 2 models of fin-bar calibration machine: ZZBJ-80 which works on fin-bar of 10-110mm with thickness ranging between 3-8mm. Also, ZZBJ-120 which works on fin-bar of 12-140mm with thickness ranging between 3-12mm.

Please refer to the below table on the specifications of the ZZBJ-120.

The uncoiler allows the mounting of fin-bar coils and feeds into the fin-bar calibrating machine. In an effort to reduce downtime, our uncoiler allows the mounting of 2 fin-bar coils, and is 180 degrees rotatable.

Interior diameter of fin-bar coil: ≥425mm
Exterior diameter of fin-bar coil: ≤1900mm

Panel Flipping/Transverse Device

The panel welding process is the bottleneck of membrane wall production, therefore we would commonly see 2 panel welders operating in the same production line. At the end of the first welding pass, the flipping/transverse device will transfer the panel to the second panel welder to begin the back side welding.

Panel Bending Machine

According to the tube size, angle and panel width required ZZ’s panel bender can again be custom built to meet your requirement., ZZ also manufacture the panel bender in conventional mechanical system or in hydraulic which is capable of bending tube size of up to 89mm.

In 2011, a patent was registered for its design of the small radius 180 degree panel bender. Such innovation was achieved in catering for the askings of solar water tube boiler manufacturers, it is also seen in certain heat exchanger designs.
