About SPR System
SPR(Self-Piercing Riveting) System
When using a high-strength lightweight material due to weight reduction of the product, it is difficult to apply melt welding due to different physical properties. Using a punch as a molding-based mechanical fastening method of Self-Piercing Riveting (SPR), the technique of bonding without pre-hole processing is performed by pressing the Rivet with strong pressure
Advantages of SPR
- High speed single job combination process without pre-drilling: 3~5 seconds
- Combination of different materials: steel, aluminum, plastic, CFRP
- Bonding without damage to coated material
- Non-combustible, low-noise, low-energy consumption bonding
- Applicable to high-tensile steel sheet: maximum equipment celebration: 10 tons
- Application by Rivet Type: Simultaneous application of 1-4 types of rivets
