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 0.8mm to 2mm
Sheet metal bottom: Embossing on sheet metal around the thread
Pilot hole preparation: Pre-punched pilot hole according to AUTORIV specifications, for thin sheets additional embossing
Die: Use of an die with embossing collar
Installation: Embossing die moves and shapes the material into the collar undercut
Used in: Sheet metal, aluminum profiles/ extruded profiles, 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
+ Good performance especially in medium-thickness sheets
+ Multi-purpose use without changing the geometry in a broad range of sheet metal thicknesses
- No diversity, less stock requirement
- No risk of mix-up (Incorrect fasteners in incorrect application)
- (Re-)use of existing automation / tooling, thus reduction of investment
+ 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
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.
