+ Simple mechanical compensation of positional tolerances possible (standard +/-0,5mm)

Greater compensation possible with custom design, possible with suitable AUTORIV thread end

  • Ensuring optimal pressing: No "NOK pressings" with risk of subsequent complaints and quality costs
  • No frequent re-teaching of the robot necessary
  • Ensuring high availability and output, thus cost reduction

Automation

The automations effectiveness and the quality of the end product are largely determined by fastener quality.
For optimal results, we perfectly match the fastener and the automation / tooling. This ensures high availability of the automation, high production output and high quality of the end product.

+ With us, the development of the automation technology comes together with the development of the fasteners

+ Each fastener is 100% vision inspected before it is shipped to you
