Steel rings - Import export

Automatic steel ring bending machine for the production of circles, spirals and radius bars for diameters from Ø 6 mm (#3) to Ø 40 mm (#14). The machine uses a system of 4 rollers, one of which is specifically to ensure the stability and consistency of the radius of the curve. The rebar combined machine CER40 can be programmed to produce automatically up to 5 different radius curves on the same bar thanks to the measuring system.

Politubes, in conjunction with DuPont, has developed a special spiral-wound tube made of heat-shrinkable polyester (Mylar HS), which enables automated fixing of permanent magnets, thereby reducing the cost of assembling these motors.Important advantages are: 1.Unlike very expensive steel rings, the spiral-wound tube also wraps around and protects the ends of the magnets, which are also subject to corrosion. 2.The trimming that often has to be done during the assembly process when using rigid rings is avoided; the Politubes spiral-wound tube adheres perfectly to the magnets, taking their shape and protecting them from cracking and scratching; this also guarantees perfect balancing of the rotor. 3.Part of the assembly process is removed, since potentially costly and often manual bandage with tape impregnated with epoxy resins can be eliminated; this avoids as well lenghty resin activation time in oven; productivity is thereby increased and hidden production costs reduced.
