Self-piercing machinery busway piercing riveting machine self-piercing riveting machine portable piercing riveer

 We have research and study the self-piercing technology from year of 1995, and the

main purpose of for joint different metal material with good sealing and protect

penetration function. The mian advantages are low energy consumption, ues small

venues and pollution-free etc. Applicable scope: coated steel sheet, aluminium,zinc,

reinforced plastic, compound material etc.

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. 

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.

Advantages of self-piercing machinery

A. Special purpose rivet with special rivet carry belt.

B. No need to drilling holes, no wast and no iron scrap occured.

C. Self-piercing processing allowed , Non metallic sandwich materials.

D.No thermal stress concentration and no damage to the surface coating.

E. High dynmic strength and far superior to the tradional spot welding.

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

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

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