The design of the mixing rod utilised a speed of 20,000 rpm and made for a more dynamic ascent of the rod. Thanks to this change, lateral guidance was sufficient and lowered the frictional wear substantially. At the critical opening in the container cover, the rod had a turbine effect, drawing the outside air into the container and sealing it in the process.
Despite the improved functionality, the number of components was reduced from eight to three. This allowed simplified assembly with a manual assembly device, which was constructed and put into operation. Zühlke assisted with the production of the injection mould, the mould sampling and the production of the pilot lot parts.
