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.

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.

Manual steel strapping tool, lightweight and sturdy, with sealless joint. Suitable for medium/heavy duty packages with flat surface for supporting the tool. It can be also used on packages with irregular shape, however a flat surface with a minimum length 150 mm is needed. Works with glossy or blue strap mm. 13-16-19 with thickness max. 0.6 mm. The holding capacity of strap dipends on material type to strap and on strap choice

Manual strapping tool for flat surfaces (sealless). Manual steel strapping tool easy and reliable to use in medium/heavy industrial duty applications. It requires a flat surface with a minimum length of 150 mm. Works with glossy or blue steel strap from mm. 13 to mm. 19 with thinkness up to 0.6 mm. The tightness of the seal depends on the material type and strapping choice.
