The Gripflow stamping system is designed to improve upon progressive die technology to produce stampings that look like they are machined while reducing user costs. The system is intended to eliminate secondary operations such as coining, shaving, finish milling, hole reaming, drilling, broaching and so on. One stamping station enables parts to be squeezed, coined, pierced and blanked within the original strip of material, thereby allowing the part to be made according to the drawing while in the die. Hole diameters as small as one-half of the material thickness can be pierced. Holes and edges have smooth, straight sides throughout the entire part thickness providing quality bearing surfaces and part function, the company says. The system can achieve tolerances of ± 0.001" and can process metals with good cold-working characteristics such as steel, copper, brass and aluminum.
