Application of self-piercing machine
1. Automotive metal sheet components
2. Washing machine, air conditioning's metal sheet etc.
3. Computer chassis, home appliances metal sheet etc.
4. Fan casing and industrial equipment application.
5. Busway's industrial engineering applications.
6. Elevator's metal sheet and other commercial facilities.
7. Other metal sheet connect occasion.
Principle of self-piercing
The end of rivet open a horn shape under the action of concave die
and riveting pin at base layer to locking it with top layer.
Generally the thicker layer at base and thickness have no limited,
ductile material at base layer. Material at base layer if joint
metal with non-metal material.
Advantages of self-piercing machinery
1 No need to drilling holes, no wast and no iron crap occured.
2 Self-piercing processing allowed Non-metallic sandwich material.
3 No thermal stress concentraition and no damage to the surface
4 High dynamic strength and far superior to the traditional
5 Forming by special die with stamping and processed quality is
6 By check the riveting point geometry size can judging the
7 No damage to plating or coating and no need after painting or
