HARTING and Sennheiser set new standards for manufacturing headset converters

HARTING Applied Technologies has developed two customised production machines for the Sennheiser Group, the leading manufacturer of headsets, loudspeakers, microphones and wireless transmission technology.

One of these new machines produces the so-called chassis. Here, two contact strips are inserted into an injection moulding tool, where they are separated and bent. The overmoulding process takes place in the next step.

A second machine produces a magnet unit consisting of two metal components, a magnet and the plastic overmoulding. Both machines perform a 100% test on each component after the overmoulding process. A robot handles the individual components and the finished parts. The magnet unit and chassis are later assembled into a converter and this is used in the Sennheiser earphones.

“Working in close partnership with Sennheiser, we came up with the product structures and production strategies very early on in the design phase. At that time, the product was only an idea. Our new production strategy enables very precise assembly of filigree Sennheiser components,” explains Dr. Volker Franke, CEO of HARTING Applied Technologies. This partnership project underlines the “ability of HARTING Applied Technologies to provide versatile customised solutions,” Franke continues.

The tool construction department builds tools of any complexity and with maximum precision, primarily for internal injection moulding and aluminium pressure die-casting production. A particular strength is the close interlinking of tool construction and special purpose machine construction. “Combining these two areas is what has made this project so successful,” states Franke.
