Solves assembly challenges

  • Reduces cycle time and improves productivity
  • Increases reliability
  • Assures quality sets time and again
  • Reduces in-place fastening cost
The principle of the SPR joint,

Piercing and joining at once on same time on of many variations, Sheets Metal to Sheet Metal ,Metal to Plastic ,AL to Cfrp,Al to Al ,Steel to AL. this system prevents eliminated pre drilling marking and welding process and provide higher productivity and more cost effective and more permissiveness assembly solutions .

What is self-piercing rivet and how does it work? 

Self-piercing riveting is a high-speed mechanical fastening process for point joining sheet material, typically steels and aluminium alloys. It is a single-step technique, generally using a semi-tubular rivet to clinch the sheets in a mechanical joint. There is also a process variant which utilises solid rivets.As the name suggests,pre-drilled holes are not required, allowing the joint to be made rapidly in one operation.The process cycle is shown in cross-section below.

The process starts by clamping the sheets between the die and the blankholder. The semi-tubular rivet is driven into the materials to be joined between a punch and die in a press tool. The rivet pierces the top sheet and the die shape causes the rivet to flare within the lower sheet to form a mechanical interlock. The rivet may be set flush with the top sheet when using a countersunk rivet head. The die shape also causes a button to form on the underside of the lower sheet; ideally, the rivet tail should not pierce this.

Advantages of self-piercing riveting include ;

  • Fast, single operation joining process
  • Can be used on unweldable materials and dissimilar material combinations
  • Little or no damage to pre-coated materials
  • No fume or heat, low noise emission, low energy consumption

Self-piercing riveting is, essentially, a proprietary process. Although the principles of operation are basically the same, there are variations from one system to another in, for example, rivet and die shape.

Benefist of Self Pierce Rivet
  • No work hole required

The self-piercing rivet pierces through the materials while fastening them together. A work hole does not need to be made in advance.

  • Secure fastening of dissimilar materials

The rivet securely fastens dissimilar materials low in weldability, such as aluminium and iron.

  • Perfect for fastening color steel plates

The self-piercing rivet fastens materials without heating and repainting after fastening is not required.

  • Clean fastening friendly to working environment

Fastening with a self-piercing rivet does not cause sparks, smoke or riveting swarf.It is a clean fastening technique friendly to working environment.
