Stamtec’s Mechanical Presses (a.k.a. OBG, OBS, OBI, or C-frame) undergo finite element analysis prior to manufacturing to ensure proper design, superior strength and maximum resistance to deflection
The Stamtec G2 series two-point gap frame press (a.k.a. OBG, OBS, OBI, or C-frame) is designed for stamping relatively long, narrow parts at high single-stroking rates or in continuous mode, using either blanks or coil stock. The G2 series provides a large die area at a very economical price and can run progressive dies that need the longer bed area. The slide on these metal stamping presses is guided by six-point, full-length box type gibs, providing excellent control of slide alignment and accuracy throughout the entire stroke.

Extra-long, box-type centered gibs guide the slide during the working portion of the stroke. The design of this mechanical stamping machine provides full control of left-to-right and front-to-back slide alignment.
Heavy, one-piece welded steel frame is fully stress relieved and designed to resist deflection, providing more accurate stampings and longer die life.
Fast-response hydraulic overload relieves the pressure of a tonnage overload in milliseconds, stopping the press immediately and protecting press and dies from damage.
