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 an economical alternate to milling the area around
Section "A" and drilling the two small holes.
Small Web-Sections – less than the material thickness
We have achieved up to 29% of the material thickness.
This part was stamped using a 2-Up Compound Gripflow Die.
The material is a low carbon hot rolled steel (SAE 1008/1010).
The material thickness is 0.080" while the two small web-sections
"A" & "B" are 0.023" – that is 29% of the material thickness.
All three holes were pierced in the Gripflow die.
The part is used in a "commercial printing mechanism" within the Retail Industry.
Gripflow was an economical alternate to drilling the two holes and
milling the oblong hole.
Small Holes & Small Web-Sections
Holes are pierced whereby the hole diameter is smaller than the material thickness. We have achieved up to 35%/29% of the material thicknes
This part was stamped 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 1 of 4 holes that are
0.098" +/- 0.001" (approximately 46% of the material thickness).
Section "B" shows 1 of 2 small web-sections that are 0.064"
(approximately 30% of the material thickness).
All six holes were pierced in the Gripflow Compound die.
The part is used in a "hard disk drive" assembly within the
Computer Industry.
Gripflow was an economical alternate to drilling the six holes.
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 1 of 4 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 1 of 2 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 an economical alternate to pressing special tapped fasteners to the four 0.365" holes and drilling the two 0.400" holes.
Stainless Steel – 300 and 400 series
This part was stamped using a 2-Up Gripflow Compound Die.
The material is 409 Stainless Steel.
The material thickness is 0.365" and the tolerance on the center hole
is +/- 0.0015" with a minimum of 85% shear.
All three holes were pierced in the Gripflow die.
The part is a flange used within the Automotive Industry.
Gripflow was an economical alternate to drilling the three holes.
300 and 400 series stainless steel with a hardness below
Rb 85 can typically produce good GF characteristics.
Copper 110 Alloy, Brass, Bronze, and Beryllium Copper.
This part was stamped using a Compound Gripflow Tool.
The material is Copper (110 Alloy).
The edges of the part required 95% shear.
The material thickness is 0.250" and the hole is 0.6875 +/- 0.002".
The narrow slots in the part are 0.125" wide – that is 50% of the
material thickness.
The part is used within a "special pump mechanism" in the
Electrical Industry.
Gripflow was an economical alternate to machining the part.
Aluminum – 2024-T3, 5052, 6061-0
This part was stamped using a 3-station progressive Gripflow Tool.
The material is 6061-0 Aluminum – 0.130" thick.
Section "A" shows one of three ports that required coining the material
to a precise shape – the opposite side of these exhaust ports have a
"raised seat" used to create a seal against a flapper valve.
The part is an exhaust valve plate used in a "pneumatic hand tool".
Gripflow was an economical alternate to "powdered-metal"
or "metal casting" or "traditional stamping" (note: all three of these processes would have required secondary machining) due to the part's complexities and tight tolerances.
