Highly complex contour areas required the smallest cutter diameters with 5-µm accuracy on 384 measuring fields, and extremely long machine runtimes: The Spe-Chip microfluidic sample carrier mould was in a league of its own. The toolmaking department at Erwin Quarder Systemtechnik in Espelkamp in Germany's Eastern Westphalia managed the project with support from Moldino.
