GRIPflow® Sample Parts

Die-Roll

We have been able to eliminate 90% of the die-roll in select areas of this part.

This part was stamped using a 3-station progressive GRIPflow^® tool. The material is a low carbon hot rolled steel (SAE 1008/1010).

Section "A" required minimum die-roll and we were able to eliminate approximately 95% of the die-roll. The material thickness is 0.315" while the two small holes are 0.215" +/- 0.002" (68% of the material thickness).

All three (3) holes were pierced in the GRIPflow^® progressive die. The part is used in a "switching mechanism" assembly within the Electrical Industry.

GRIPflow^® was a cost-saving alternative for milling the area around Section "A" and drilling the two small holes.

Small Holes & Small Web-Sections

Holes are pierced whereby the hole diameter is smaller than the material thickness - we've achieved as low as 35% of the material thickness!

This part was stamped - and all six holes pierced - using a GRIPflow^® Compound Die.

The material is a low carbon hot rolled steel (SAE 1008/1010). The material thickness is 0.212".

Hole "A" shows one of four holes that are 0.098" +/- 0.001" (approximately 46% of the material thickness).

Section "B" shows one of two small web-sections that are 0.064" (approximately 30% of the material thickness).

The part is used in a "hard disk drive" assembly within the computer industry.

GRIPflow^® provided a cost-saving alternative to drilling the six holes.

Coined Features

Countersinks, Counterbores, Relief Pockets, and Raised Projections.

The combination of a GRIPflow^® die and hydraulic press is perfect for coining applications since the velocity of the press ram can be adjusted and controlled. If required, the ram can dwell at the bottom of the stroke for a micro second or stutter stroke to achieve the various coined features.

The part pictured is used within an automotive emergency hand-brake assembly and shows some coined chamfers. The material is AISI 1020 steel 0.187” thick.

The three deep chamfers (approximately 2/3 of the material thickness) are made with a progressive GRIPflow^® die that eliminates drilling and machining secondary operations. Also, the center hole (tight tolerance of +/- .001”) is the pivot axis for the teeth which were also made within the stamping die. The holes and edges of the part have at least 85% shear providing a good bearing surface for the mating parts.

Increase Material Thickness

Accomplished by extruding material to increase the material thickness in specific areas.

This part was stamped using a 3-station progressive GRIPflow^® tool.

The material is a high strength, low carbon hot rolled steel (SAE J1392 Grade 050).

Section "A" shows one of four holes that required adding material to the thickness. We were able to extrude the area around the four 0.365" holes adding 0.250" to the already existing 0.396" material thickness.

Section "B" shows one of two 0.400" holes close to the edge that have a web-section of 0.256" (approximately 65% of the material thickness).

The part is used in a "axle support" mechanism within the Automotive Industry.

GRIPflow^® was a cost-saving alternative for pressing special tapped fasteners to the four 0.365" holes and drilling the two 0.400" holes.
