Innovative Blind Rivet Offers Fastening Solution that Significantly Reduces Raw Material and Installed Blind Rivet Costs
Harry E. Taylor :
Over the past seventy plus years of automotive blind riveting history, very little has changed. The basic open end break-mandrel blind rivet is still, relatively, the same, and over 90%+ of the mandrel used to set the blind rivet is discarded after the blind rivet is set.
Sure, blind rivet setting tools have steadily evolved. Blind rivet setting tools have gotten lighter as plastics were introduced and devices to present blind rivets to the setting tool and collect the spent mandrels have been developed.
Those selling blind rivets to the automotive industry have generally promoted a lower and lower “installed cost” for this unique fastening solution, but this has always meant installing the blind rivet faster or collecting the 90%+ of the spent mandrels that need to be discarded.
Even though the automotive industry uses millions of blind rivets in a unique applications, it is rare to see a special systems approach where a unique setting tool design, setting method process modification or specialty configured blind rivet offering the lowest possible installed cost has been provided for a unique automotive application. Since, a blind rivet mandrel contains a considerable amount of material that is later discarded; the cost associated with this discarded raw material remains significant.
Not realizing there was more that could be done to reduce the cost of the associated blind rivet in high volume automotive applications was marketing oversight. U.S. Patent Application 11/654,123 for a unique blind rivet, including modifications to the installation tooling and setting method, was recently filed to alleviate this oversight. These innovations, when implemented and brought to “The Tipping Point”, will enable blind rivet users to save up to many thousands of dollars (depending on blind rivet usage) in necessary blind rivet purchases.
Since overall material in the new blind rivet is reduced by up to about a third, the purchase prices and installed costs are substantially reduced. This innovation will benefit OEM’s in many industries, but due to the significant volumes of blind rivets consumed in the automotive industry, significant relevant savings will be realized.
Inquiries on how to modify blind rivets and the associated fastening system components for specific fastening assembly solutions that manufacturers and assemblers may have are welcomed.
