H-frame presses are large floor units that combine a steel frame, a press cylinder, a pump and a movable bolster—forming an "H" shape. These presses can be used for a variety of applications, including in repair and maintenance facilities and on production lines for assembly. H-frame presses are typically paired with hand pumps for low-volume applications, with air pumps in facilities where pressurized air is available or with electric pumps for consistent operation. Cylinder size can also vary depending on the force needed and the application.H-Frame Hydraulic presses are beneficial for medium and low-volume production applications. The simple, rugged design is suited for a wide range of applications and makes maintenance easier.
