SUPERIOR SHEARING FOR A CLEAR-CUT DIFFERENCE.
Stamping or fineblanking? Fineblanking is the procedure of choice whenever stamped surfaces need to satisfy specialised requirements and minimal die break is the order of the day. With etampa's ultra-modern fineblanking presses, we achieveFINEBLANKING exceptionally right-angled surface cuts with up to 100% fully-sheared edges. Here, too, etampa keeps the customer in mind: the high degree of contour and dimensional accuracy means some later processing steps such as deburring or grinding may be skipped in their entirety.
MATERIALS, TOOLS, PRODUCTION.
The fineblanking presses used at etampa can apply forces of between 40 and 250 tonnes. By using the latest generation of servo-driven fineblanking presses, multiple velocities can be applied during a single stroke of the press. For etampa's customers, this means that overall production achieves a distinctly higher level of profitability, since output is significantly boosted while quality is maintained at the same high standard. Strip materials used by etampa include steel and stainless steel, non-ferrous metals, aluminium and titanium; for fineblanking, materials with thicknesses of 0.5 mm to 6 mm can be worked. etampa manufactures parts using compound-die production or a progressive die system. With a compound die – "a one-stroke shot" – the stamped part is subjected to multiple operations simultaneously, while a progressive die permits the combination of many different work steps. Taking extremely tight tolerances into account, operations applied to fineblanked parts may include their being bent, deep-drawn, coined, cut, thread-rolled, cranked or cross-hole punched. At etampa, series volumes of parts produced may exceed as many as 50 million units per year.
