Application area

Suitable for: Insertion in metal sheets with tensile strength less than 600N/mm². It can be used in galvanized, painted metal sheets

Sheet thickness: Used for metal sheets with thicknesses from 2mm upwards without limitation. Adaptable for sheets with thicknesses from 1mm

Sheet metal bottom: Flat without indentation, optimal fastening characteristics (clamping with a large surface area)

Pilot hole preparation: Pre-punched pilot hole according to AUTORIV specifications

Die: Use of a flat die (optimal downtimes)

Installation: Torque absorbers move and shape the material into the collar undercut

Used in: Sheet metal, aluminum profiles/ extruded profiles, aluminum casting, magnesium casting, hydroformed parts

Application examples

  • Lightweight construction
  • Electric and hybrid cars
  • Body-in-white, module carriers, battery trays, bumpers, crash boxes, doors, lids, engine hoods, axles, hinges, seats, safety systems, instrument panels, reinforcements, sun roofs, roof panels
  • Truck trailer manufacturing, heavy trucks, agricultural machines
  • HVAC heating, ventilation and air conditioning systems
  • Electronic components and devices
  • Elevators, escalators, conveyors
  • White goods

Highlights

+ Very low press-in forces

  • Lighter C-frame on the robot
  • Larger projections / overhangs possible
  • Shorter cycle times
  • Pressing into undercuts or profiles is easier to handle than with other fasteners

+ Minor material movement during the press-in process

Lower risk of warping of workpieces, especially with many setting positions

+ Flat die

  • Lower risk of warping of work pieces
  • Flat sheet metal bottom with largest surface possible for the preload through tightening

+ Multi-purpose use without changing the geometry. Customized solutions for sheet thicknesses less than 2mm possible

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

Greater compensation possible with custom design

  • 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

+ Small diameter

Setting in limited installation spaces is possible

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

Customized configuration

We have a tailored solution for you. We are happy to make fastener adjustments for your specific application. A variety of parameters, related to the field of application, geometry, characteristics and surface of the fastener, are optimized according to your requirements.

+ Customized developments are one of our strengths! If your specific requirements cannot be met with a standard application, we will be happy to provide you with a suitable custom solution

+ Customized solutions that we develop for you, are verified for functionality

Within application testing, we simulate your production environment and test functional parameters and relevant characteristics of the fastener.
