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.

f you want to apply VELA type eyelets you must first of all choose which eyelet you want to apply. VELA eyelets range from type 21 (with 7 mm internal hole) to type 150 (with 43 mm internal hole). Once you have chosen the eyelet, you move on to the choice of the punching kit/riveting kit.

The strapping tool ST IMPA 13/16 is usable with both polypropylene strap and polyester strap (green, high resistance) from 12 to 16 mm. Given the high tightness of the seal it is recommended to use a polyester strap. The breaking load depends on the strap of choice.

Strapping tools for metal strapping 10-13-16/18-19-20 mm manual for flat surface, joint with copper-plated steel seal. Simple and cheap, is used for strapping packages and pallets of any size. This strapping tool requires a flat surface with a minimum length of 200 mm. In general it is not recommended in case of high productions. The sealing depends on the type of material and strap.
