G2 Series

G2 SERIES GAP FRAME PRESS

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 is guided by six-point, full-length box type gibs, providing excellent control of slide alignment and accuracy throughout the entire stroke.

Tonnage Range: 121 - 330

Stamtec presses can be customized to meet a wider range of SPM, stroke, rating point (BDC), bed and other specifications and dimensions.
