Deep Drawn & Servo Stamping
Rely On Ajax Servo Presses For Speed & Precision
Deep Drawn & Servo Stamping Technology.
Ajax servo presses use advanced servo-motor technology and closed-loop control for precise motion, position, speed, and force control throughout the stroke. This enables highly accurate and repeatable results ideal for complex parts with tight tolerances.
These presses allow programmable stroke length, slide velocity, and force profiles within a cycle. This flexibility handles a wide variety of parts, dies, and speeds on the same machine. Different motion profiles are easily programmed, making servo presses ideal for tasks like deep drawing.
Although very precise, servo presses can operate at high speeds comparable to mechanical presses and faster than hydraulic ones. They achieve full working energy and tonnage at any speed for efficient high-speed production. Their electric operation is also more energy-efficient.

Deep Drawn & Servo Stamping FAQs
Why Choose Deep Drawn Stamping?
Once the necessary tooling is developed, deep drawn stamping provides efficient, repeatable part production that is highly cost-effective for large quantities of parts. Deep drawn is ideal for pans, cans, housings, enclosures, and other hollow parts without resorting to welding or seams. This saves additional production steps and reduces costs.
Deep drawing achieves consistent wall thickness, precise dimensions, and tight tolerances—crucial for parts where fit and finish are critical. Because the process yields smooth, seamless surfaces, deep drawn parts are well-suited for visible or cosmetic applications.
Why Choose Servo Stamping?
Servo presses use electric actuators rather than traditional mechanical flywheels or hydraulic systems. The movement of the ram is controlled with precision, constantly adjusting the slide’s speed, location, and dwell at any point in the press stroke. This fine-tuned control enables the use of a wider range of materials and part geometries while still achieving efficient production. Because servo presses can slow down the ram during critical forming points (like bottom dead center), they reduce material stress and allow for greater formability, ideal for high-strength steels, aluminum, and deep drawn parts. The result is less springback, wrinkling, and cracking.
