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.

The panels have standard dimensions with heights ranging from mm 1000/1 250/1 500 and lengths from mm 2950/3950; they can be made to be housed inside HE120O/1 40/1 60 profiles. The panel frame consists of horizontal and vertical beams with different insertion sections of mm 80 for HE 160 profile, mm 60 for HE 140 profile and mm 40 for HE 120 profile; the 20mm-thick rear and front side, representing the sound-insulating part of the barrier, consists of a battened or tongue&grooved matchboard. Inside the panel no sound-absorbing material is fitted. The front face is embellished with motifs and drawings of various kinds. An "EPDM" seal is fitted on the vertical sides of the panel front to lock the panel inside the HE profile; an "EPDM" flat seal is also fitted at the panel bottom to avoid breaks between the panels. Bolts and screws include stainless steel screws, 15-micron passivated ring nails, galvanized clips. The wood used is impregnated pinewood; all the wooden elements are impr
