While producing touch displays for tool dispensing systems, kessler systems relies on our ONSERT® fasteners.

As an expert for conductor plates, electrical components as well as systems and tools, kessler systems has produced since its foundation over seven million components and realised more than 1,000 projects worldwide.

Initial situation


Display fastening on tool dispensing systems

One customer of Kessler systems is Gühring KG, one of the worldwide leading manufacturers of rotating precision tools for metal cutting.
Its portfolio comprises also the tool management. Tool dispensing systems including IT-based management connect production with information technology and increase consequently efficiency as well as flexibility. The integrated Gühring Tool Management Software is simply used via the attached touch display on the tool dispensing system.

kessler systems assembles these displays for tool dispensing systems in their own production. In order to fasten the display halves, process-reliable joining elements should be used. They have to be fixed invisible on the glass surface to emphasise the design of the touch screens. Moreover it is assumed, that the finished display then can be easily screwed to the housing of the material dispensing system. In case of larger glass or touch screens, the processing of the used elements should also be flexible and efficient.

Customer profile

Conductor plates and electrical components

Königseggwald, Germany




ONSERT® – Bonding of fastening elements

The ONSERT® Smart – fastening elements with a socket made of transparent plastic are bonded to the customer component using light-curing adhesive. The short cycle times, the material-friendly process as well as the flexibility of the fasteners and the processing are the most important aspects.

The ONSERT® technology allows the adhesive bonding of various fasteners to a wide range of materials. As a specialist in mechanical joining systems, Böllhoff has developed together with DELO, the expert in intelligent adhesive technology, a new fastening system which combines the best of both worlds.



Process-reliable fastening of display halves

With the ergonomic ONSERT® Portable and its short curing times, kessler systems processes both smaller and larger quantities efficiently. About 10,000 pieces of ONSERT® Smart fasteners in the dimension M 6 x 18 are assembled annually in displays for tool dispensing systems.

Customer benefits

  • Full mechanical load capacity immediately after irradiation (< 4 seconds)
  • Fastening elements cannot be seen on the visible side
  • The ONSERT® joint does not need a drilling into the glass surface
  • Can be processed manually or automatically
