Customized developments are our strength

Some projects cannot be realized with standard solutions. Thus, custom design fasteners with suitable automation are required. However, most system suppliers only sell standard products. Fastener manufacturers also often only have standard fasteners in their product range.

Finding a vendor who is also capable of developing customized fasteners is not easy.

You will also not find another system supplier who does both developing special design fasteners and corresponding automation.

Thanks to our many years of experience as a toolmaker and our large development capacity, custom developments are our strength and a unique selling point on the market. Our special solutions come from our modular system, which has been built up over decades and proven in series production.

Adaptations

for difficult installation situations

It is often necessary to place fasteners in angular positions to meet difficult installation situations.

On request, we can also offer special solutions for the installation of fasteners in hard-to-reach places, in tight installation spaces or at specific angles, such as:

Further possible adaptations:

  • Adaptation to a special fastener
  • Adaptation to a special tool environment
  • Individual application direction and fastener delivery
  • Adaptation to the workpiece to be processed and the required component depths

Application example

Rivet nut and spacer bushing in a transfer tool

Sheet metal part, rivet nut and spacer bushing - Assembly in transfer tool

Our customer's task was to develop a combination of a rivet nut and spacer bushing. These two fasteners should be automatically assembled in just one single stage in the transfer tool. This setting process takes place in a a single die station, which is at a 90-degree angle to the stamping direction. This is done in a very small working area.

We have developed the fasteners required for this, rivet nut and spacer bushing. We have run through a series of necessary application tests to validate the process.

The fasteners were developed with the consideration of being able to set them process-safely in the transfer tool. Thus, the development of fasteners took place simultaneously with the development of the automation technology.

With our profound know-how in the critical areas, a project of this complexity could be realized effectively and successfully.

Application example

Special rivet and bushing in a progressive die

Sheet metal component, special rivet and sliding bushing - Assembly in progressive die

The task was to assemble our special design fasteners, a special rivet and a glide bearing bushing with a wall thickness of 0.5 mm, automatically by flanging with calibration of the inside diameter in a progressive die.

Initially, the assembly of this component should have been done completely outside the press in a subsequent operation as orbital riveting. Due to a detail modification in the riveting area, we were able to bypass the orbital riveting process and assemble both fasteners under the press. This eliminated various subsequent work steps, which resulted in significant cost savings for our customer.

For this application, we were also the only supplier who could realize a project of this complexity effectively and successfully.
