Self-piercing riveting machine

  We have research and study the self-piercing technology from the year of 1995 and the main purpose of for joint different metal material with good sealing and protect penetraition function. The main advantages are low energy consumption, use of small venues and pollution-free etc. Applicable scopes: coated steel sheet, aluminium, zinc, reinforced plastic, compound material etc.

Principle of Self-pircing

  The end of rivet open a horn shape under the action of convave die and riveting pin at base layer to locking it with top layer. Generally the thicker layer at base and same thickness have no limited, ductile material at base layer. Metal material at base layer if joint metal with non-metal material.

Application of Self-piercing machine

Automotive metal sheet components

Washing machine, air-conditioning’s metal sheet etc

Computer chassis, home appliances metal sheet etc

Fan casing and industrial equipment application

Busway’s industrial engineering applications

Elevator’s metal sheet and other commercial facilities

Other metal sheet connect occasio

 

Advantages of Self-piercing riveting machine

Special purpose rivet with special rivet carry belt

No need to drilling holes, no waste and no iron crap occurred

Self-piercing processing allowed Non-metallic sandwich material

No thermal stress concentration and no damage to the surface coating

High dynamic strength and far superior to the traditional spot welding

The self-piercing forming by special die with stamping and processed quality is stable

By check the riveting point geometry size can judging the riveting quality

No damage to plating or coating and no need after painting or plating
