Clinch fastening through plastic deformation without auxiliary materials.

No auxiliary materials such as rivets are needed, the power source is only air, no heat is generated, and bonding can be done instantly. Low-cost, high-performance fastening.

In the context of the demand for CO2 reduction, the RIVCLINCH fastening method, which uses only air as a power source, generates no heat, and does not use auxiliary materials such as rivets, relies on plastic deformation. By applying multiple points, it is possible to achieve equivalent strength when compared to spot welding and shear strength with SPR. Additionally, it is capable of fastening thin sheets, which are said to be difficult to weld, as well as combinations of materials with different properties and dissimilar materials. Examples include: - Combinations with a high ratio of total plate thickness to the thinnest plate thickness - Aluminum 5000 X Aluminum 6000 - Plate assemblies that require multiple welds in spot welding, etc. The only auxiliary materials needed are the die and punch at the tool tip. The tools can be hand tools, stationary tools, or automation that can be held by robots. We will propose the most suitable option based on the production scale.
