Gripflow Process

Gripflow is a precision metal stamping process that produces highly accurate parts with smooth square edges. Compared with its rivals, Gripflow produces parts with the characteristics of Fineblanking at a lower cost. Gripflow leverages the merits of conventional stamping and Fineblanking processes to derive an economical alternative yet high-quality product.

Gripflow can:

  • Eliminate secondary machine operations
  • Pierce holes smaller in diameter than the stock thickness
  • Coin countersinks the entire thickness of the stock material
  • Stamp gear teeth
  • Hold close tolerances
  • Make the smooth-edge only where it is required
  • Improve your part’s flatness
Features:
  • Smooth-edge surfaces up to 100% shear
  • Minimal hole and position tolerance requirements at 0.025mm (0.001″)
  • Superior flatness at 0.025mm (.001″) per linear inch
  • Holes can be pierced close to part edges: Web of 50% of material thickness
  • Net part shape from a single-station or progressive die
Cost:
  • Gripflow™ tooling is less than fineblanking dies due to the elimination of the V-ring
  • Gripflow™ unit prices are typically less than fineblanking as a result of greater material utilization and tonnage efficiency
  • Gripflow™ tooling is significantly less than conventional stamping with progressive stations. These savings are a result of multiple operations performed in a single-station die
  • Gripflow™ unit prices can compete with conventional stamping if secondary operations are avoided
