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
The Stamtec PL2 Series double crank press features our Link Motion Drive Technology, designed for deeper or more complex forming, at high single-stroking rates or in continuous mode, using either blanks or coil stock.
Stamtec’s link motion drive technology decreases slide velocity by up to 40 percent during the working portion of the stroke so the material flows more effectively while the non-working portion of the stroke increases by an offsetting amount to maintain high production rates.

Hydraulic Overload Protection System (H.O.L.P.)
Stamtec’s unique dual-valve automatic hydraulic overload protection system protects each side of the double crank press individually from overloads.
Air Counterbalance System
The weight of the slide, connection housing assemblies, upper die, etc., is offset by an adjustable air counterbalance system.
Lubrication System
All anti-friction bearings, sleeve bushings and gibs are lubricated by a sequencing self-monitoring re-circulating oil lubrication system which is interlocked with the mechanical press emergency stop circuit.
Digital Die Height Indicator
A die height indicator is mounted on the front of the slide for operator convenience in making die height adjustments.
Die Safety Block
Two (2) Die safety blocks with holders are included. The safety blocks are supplied with a plug and receptacle interlocked into the press controls.
Press Pneumatic System
The pneumatic system includes the necessary regulator valves, gauges, lubricators, and air filters for each double crank press.
Knockout Bars (Optional)
As a standard feature, the slide is arranged to accept knockout bars.
Every Stamtec mechanical press features advanced, user-friendly automation controls with fully programmable on-screen displays for easy set-up, start-up, operation and diagnostics.
Our standard presses come equipped with OmniLink 5100-APC Press Automation Controls.
