2 D DI MICHELETTO DONATELLA E DOMENICO S.N.C.

Spark erosion involves removing material from a conducting part and eroding it to give it the desired shapes and dimensions by means of electrical discharges. In the wire sparks erosion process an unwinding metal wire, under tension, is immersed in water or in another insulating liquid (dielectric) with the part to be worked. The current transmitted forms an electric arc which gives rise to precise, programmed degradation of a section of the part. The residues created by wearing of the part are removed by the water or dielectric liquid. STEEC carries out both spark erosion and fine wire micro spark erosion operations Wires spark erosion and machining Equipped with the latest wire spark erosion technologies, STEEC is able to carry high precision cutting with wires of standard sizes whose diameter may vary from 0.15 to 0.25 mm in all types of mechanical parts.

The operator wrap the product with the strap, put the two ends through the buckle and places into the strapping tool. The first end is locked with the brake while the second is placed under the cutter and inside the tension roller. Increasing the tension of the strap, the buckle keeps the tension. After reaching the desired tension the strap is cut automatically by the tensioning device.

The strapping machine with side head is recommended in all sectors in which, with traditional machines, processing residues such as grease, liquids, etc., cause operating problems. The SP92-E is suitable for products with minimum dimensions of 10x50x100 mm; uses strap with a width of 12 mm and a maximum thickness of 0.65 mm. Equipped with worktop with adjustable height and device for automatic shutdown, after 60 sec. of inactivity.

Pneumatic strapping tool with vibration welding (heating by friction) for straps in polyester PET width 25-32 mm and max. thickness mm. 1,27. Compact, handy, easy to use, is suitable for closing all kinds of flat packaging. Thanks to a very short base and the command of reverse rotation of the roller it may also strap round packing with a minimum diameter of mm. 700. The operator simply inserts the two overlapped strips into the strapping tool, press a button to make the tension, a second button to get the vibration welding, and at the end a third button to pull out the tensioning device effortlessly.
