In January 2005, Dubuque Stamping acquired the GRIPflow stamping process license through Ebway Corporation. A separate corporation called Grip Flow of Iowa was formed. The first press has a capacity of 400 tons with a 0.5"-thick coil line. Now a second 150-ton press has been installed for smaller parts. This process is a perfect fit for Dubuque due to the location of the company, the mix of current and potential customers and the fit with our other in-house capabilities such as double-disc grinding and heat-treating.
GRIPflow Stamping Process: GRIPflow is a patented metal-stamping process that produces highly accurate parts with smooth, square edges. Characteristics of the GRIPflow process over conventional stampings include:
| • |
Elimination of secondary machine operations. |
| • |
Piercing of holes smaller in diameter than stock thickness. |
| • |
Holes closer to the edge of the part than stock thickness. |
| • |
Production of gear teeth and other various configurations. |
| • |
Close tolerance on holes and contour of part. |
| • |
Smooth part edges. |
| • |
Better flatness than conventional stampings. |
| • |
Minimal amount of die roll on part. |
The GRIPflow stamping process is a low-cost alternative to fine blanking. |
