Gripflow

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.

The process uses a conventional, single-action hydraulic press with CNC controls, which allows the production speed to be controllable in the cutting process. A stamping is squeezed from the parent material accomplished by minimal clearance between punch and die components. The material retention during stamping ensures high-repeatability from part to part and dimensional accuracy to specifications. Production rates are dependent upon part size, material type and thickness.

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
