 In January 2005, Dubuque Stamping acquired the GRIPflow stamping process license through Ebway Corporation. A separate corporation was formed called Grip Flow of Iowa. The first press has a capacity of 400 tons with a 0.5"-thick coil line. The capacity of future GRIPflow presses will be based upon the size of new parts coming on-line. 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.
