Mechanical Presses

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

2-Point and 4-Point Eccentric Geared Straight Side Presses

Stamtec four-point straight side presses are designed to run large dimension dies, both left to right and front to back. Our four-point straight side press can also run progressive or transfer dies, as well as large, odd-shaped or deep-formed parts that require a transfer system to move the part through the die.

Press Highlights

Stamtec will work with the transfer system provider of your choice (e.g., HMS, Wayne Trail, Linear, Gudel, Atlas) to integrate the transfer system completely with your straight side press, feed line and other peripheral equipment as necessary.

Low-inertia, high-torque, eccentric-geared drive system design featuring precision-cut, steel-rim eccentric gears; plunger guiding; and double-helical gearing for the drive shaft and intermediate gears—all lubricated by an enclosed oil bath and spray system.

These mechanical presses feature eccentric gear drives with plunger guides on each connection to control side thrust and deliver precision slide tracking throughout the stroke.

A press machine, also known as a forming press or a stamping press, is a heavy-duty industrial press. During the forming process, it applies tremendous, controllable pressure to plastically deform or separate a mold on sheet, strip, tube, or profile, producing a workpiece or semi-finished product of the desired shape and size (e.g., changing or adjusting the dimensions of steel, aluminum, or other materials). Put, its primary purpose is to “punch” and “press” thin sheet materials, making it widely used in the manufacturing industry.

Press machines come in various types but share core components: a rigid frame/base and a punch and die set, where the punch is mounted on the moving ram and the die is secured to the stationary platen (worktable). The machine applies controlled force to sheet metal through a power system that drives the ram downward.

Most assembly presses consist of three fundamental parts:

Frame: Provides structural integrity.

Ram (Slide): Delivers vertical pressing force.

Platen (Bolster Plate): Supports the die and workpiece.

• Servo Presses: A servo motor drives a ball screw/timing belt system, translating rotary motion into linear ram movement. Programmable controllers adjust stroke length, speed, and force profile in real-time for each operation.
• Pneumatic Presses: Compressed air enters a cylinder, pushing a piston downward to drive the ram. Air pressure (typically 6-8 bar) determines force output, while flow valves control speed.
• Hydraulic Presses: Hydraulic oil pressurized by pumps (gear/piston) flows to cylinders, pushing pistons to move the ram. Relief valves limit maximum force, while proportional valves control speed/position.
• Mechanical Presses: An electric motor spins a flywheel, engaging a clutch to transfer energy through crankshaft/eccentric gears. This converts rotational motion into linear ram movement with fixed stroke length.

We specialize in servo-electric and pneumatic presses, while offering custom hydraulic solutions like our recently delivered 4-column dual-cylinder hydraulic press featuring multi-point synchronization control for uniform pressure distribution.

Our press machines can address the shortcomings of traditional processes. Our main servo + pneumatic solutions have significant advantages in lightweight and high-precision areas, while our hydraulic customization capabilities can complement the needs of heavy industrial scenarios. For example, we can use servo-hydraulic hybrid systems or servo-pneumatic hybrid systems to address the shortcomings of a single process, thus ensuring both precision and efficiency. At the same time, targeted selection should also be based on material properties (thickness/ductility), production requirements, and precision level. If you are not sure how to choose, don’t hesitate to get in touch with us.
