“Orlock Rivet” Before and After Pics

Thursday, August 27th, 2009
Why Blue Pneumatic will make a difference: The story continues . . .
Recently, we set out to solve a rivet problem, that until 6 months ago, could not be solved. We were faced with
a reputable, internationally know, Bus manufacturer  who had major leaking in the “drip rail” of  the bus. Let me show you how we approached and solved the rivet problem. By the way, the problem started because the customer was using inferior, multi-grip ( Avex sylyle rivets) in this application.  A good rivet but incorrectly applied.

Before

Leaky inconsistant multi-grip rivets.
(Caused $14,000 in warranty
repairs)
After
Consistent “Orlock” rivets with backside
flange and positive pin retention sealed
out the water.
Positively retained pin can be visually inspected from outside the workpiece!

In short, this excerpt in an engineering summary. I invite you to share your stories relating engineering challenges that you may be facing, or are facing now!
