Mechanical, Forging, & Servo Presses for Your Complete Press-line Solution

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 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.

TONNAGE RANGE: 121 - 330

Press Advantages

G2 series 2 point gap frame press - Stamtec 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.

Standard Features

Wet clutch and brake
Flywheel brake
Hydraulic overload system
Air counterbalance system
Automatic lubrication system
Digital die height indicator
Removable, flanged, T-slotted slide plate and bolster
Motorized slide adjustment
Press control with:
- Six programmable limit switches
- Four programmable die monitor inputs
- Six-digit part and batch counters
- LCD display screen for status and fault messages
- LED display for crank angle and spm
- Interlocked die safety block
