A widely used mechanical joining technology that connects similar or dissimilar materials without pre-punching. Compared to welding, SPR offers lower energy consumption, and when combined with adhesive bonding, improves joint strength.
Limitations: Difficult to disassemble and replace. Different material combinations (type, thickness, hardness) require specific rivets, punches, and dies. Rivets are costly. Common defects include misaligned, missed, or overlapping rivets, as well as cracking or breakage during the process.
2.2 FDS (Flow Drill Screw Equipment)
A thermo-mechanical joining process. The system includes a drive unit, FDS rivets, and joining plates, and features single-sided operation.
Limitations: High equipment cost and expensive screws. Single-sided joining requires rigid material to prevent joint failure. Rivets are heavy (~5g each), and excessive use increases vehicle weight, limiting lightweight design.
2.3 TOX Rivet-Free Clinching Equipment
Primarily consists of a gas-liquid booster cylinder, stamping die, and control system. It is a double-sided joining technology.
Limitations: Low joint strength, suitable mainly for non-load-bearing components like closures and auxiliary structures.
3. Technical Advantages of Flush Self Piercing Riveting Machine
Heron’s Flush Self Piercing Riveting Machine introduces a refined joining concept that improves structural strength while maintaining flush surface quality.
3.1 Superior Material Compatibility
Capable of riveting diverse materials—including high-strength aluminum alloys, hot-formed steel, and carbon fiber—and supporting multi-layer riveting up to 9.1 mm total thickness. The forming quality is excellent, making it suitable for appearance parts. Rivet heads can be pre-painted or electroplated, with no surface bulging after riveting.
3.2 One-Step Forming Process
Punching and riveting are completed in a single cycle, eliminating the need for pre-drilled holes.
3.3 High Structural Performance
The flush self piercing riveting machine delivers stable shear and tensile performance while minimizing cracking risks at the rivet interface.
3.4 Corrosion Resistance
Rivets can withstand up to 480 hours of salt spray testing, with special rivets offering extended anti-corrosion performance based on specific requirements.
3.5 Flexible Feeding and Automation Integration
Supports both air-blown and clip-type automatic rivet feeding, ensuring fast riveting cycles and high productivity.
