Insert your layers of sheet steel, aluminum or composite into the machine, ensuring the thicker sheet is on the die side for optimal results.
The rivet tooling closes, firmly clamping the workpiece against the rivet die.
The rivet punch swiftly drives the Self-Piercing Rivet through the layers, cutting through with precision.
The rivet punch creates a flush finish, and the rivet flares out into the final layer, forming a permanent and sturdy joint.
Finally, the rivet punch and holder retract, releasing your perfectly assembled workpiece in a matter of a second (or less).
What are the advantages of SPR?
Low training requirements for operators
Eco-friendly solution, no welding fumes
Strength & versatility
No pilot hole drilling required
No heat affected zone
Perfect for pre-coated material
Self-piercing rivets and clinching are non-thermal processes, meaning they do not generate heat during assembly. This eliminates the risk of warping or distortion in materials, making them ideal for joining material that is less than 0.25" (6.3mm) thick or sensitive metals.
Additionally, these methods are faster, requiring significantly less setup time than welding, which can boost production efficiency. Self-piercing rivets and clinching create joints without the need for consumable materials like welding wire or filler metals, resulting in cost savings. They also produce cleaner, more aesthetically pleasing seams, making them ideal for visible or finished surfaces.
It's important to note that welding still has its place in manufacturing. In scenarios where extremely high strength is required, or in applications involving thicker materials, welding may be the superior choice. Moreover, welding offers greater flexibility with a wider range of materials, and it's often the preferred method for critical structural components.
