Process Overview
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
Costs:
- 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 that 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 oprations are avoided.
