What Is Self Pierce Riveting?
Self pierce riveting is a mechanical joining process where a semi-tubular rivet is driven through layered materials, piercing the top sheet and crimping within the bottom layer to create a secure, flush joint. The method is especially suited for joining aluminum, steel, and other mixed or coated materials where welds may be difficult or ineffective.
Key Advantages of SPR
No need for holes or heat: Fast, energy-efficient installation without base material damage
High-speed automation: Suits both robotic cells and standalone stations for mass production
Perfect for lightweight, complex designs: Excels in automotive bodies and intricate assemblies where access and fit are challenging
Minimal impact on appearance and aerodynamics: Produces flush, attractive connections
