Mechanical joining by Emhart - SPRs and clinches in one system
Where spot welding ends, self-piercing riveting - or clinching - begins. Form-fit sheet joins of different materials without pre-punching - nearly effortlessly.
Tucker SPRs
The connecting element for joining aluminium parts, mixed connections and combined joining and gluing without emissions. The special shape of the rivet guarantees high stability.
- Higher dynamic stability than resistance spot welding
- Fully automated feed
- Riveting without pre-punching
Tucker equipment for joining
Tucker equipment for joining systems combine three technologies in one modular system: Self-piercing riveting with a semi-hollow rivet, a punch rivet and clinching.
These techniques are used to
join materials which cannot be welded easily:
These include
- Aluminium - aluminium
- Aluminium - steel
- High tensile steel
