Starting in 1983 as a service technician at Pfaff, Heinz Sepke worked his way through all departments, such as research & development, until he was finally responsible for project management with global focus.

In 2007 Pfaff, headquartered in Wuppertal (Germany), was sold to the FLSmidth Group. The plant in Wuppertal was retained and Heinz Sepke continued in the role of project manager with global focus.

At the end of 2014, FLSmidth decided to close the plant in Wuppertal site. Heinz Sepke saw great potential in innovating the machines and found a new company – QCS Rohrpost GmbH (meanwhile QCS LabAutomation GmbH)- together with his technicians and programmers who also learned at Pfaff.

From then on, QCS developed its own equipment and, due to its history, is also very familiar with machines from Pfaff and FLSmidth.
