Stamtec GHS Series High-Speed Gap Frame Press

High‑Speed, Precision Gap Frame Power Presses

The Stamtec GHS Series is a line of high‑speed, precision gap frame (C‑frame) power presses in 22, 44 and 66 ton capacities (20, 40 and 60 metric tons), with speeds up to 750 strokes per minute and a 1.2‑inch stroke.

It joins Stamtec's other gap frame presses: the 1‑point OCP and GL1 Series and the 2‑point G2 Series.

Key Features

• Cast iron frame: high‑strength cast iron, stress relieved for lasting precision
• CMM‑inspected components: critical components are inspected on a coordinate measuring machine to ensure they are concentric and true
• Dynamically balanced crankshaft: maintains precision at high speeds
• Recirculating lubrication: forced circulating lubrication system
• Slide adjustment: manual slide adjustment with a hydraulic locking device, and a die height indicator accurate to 0.01 mm
• Crankshaft encoder: precise crank angle detection
• Variable‑speed drive: main motor equipped with a VFD (variable frequency drive)
• Air connections: 3/8" air source and air ejector receptacles, standard

How to Choose the Right High‑Speed Gap Frame Press

1. Tonnage: estimate your job with our press tonnage calculator and allow a margin.
2. Die size: compare your die to the bolster and slide plate areas.
3. Stroke and die height: the GHS Series has a 1.2‑inch stroke. For small parts that need deeper or more complex forming, Stamtec offers the GL1 Link Motion Series.
4. Speed: match the strokes per minute to your feed and part‑out rate.
5. Feeding and monitoring: plan the uncoiler, straightener, feeder and tonnage monitor with the press.
