Powerful, short cycles times, high precision, low energy consumption and low noise - the STENHOJ SERVO-hydraulic press redefines the standards of industrial presses.
Traditionally, mechanical and hydraulic presses have each brought unique benefits to industrial production. While the mechanical press is characterised by high stroke speed, high repeatability, simple set up and less maintenance, the hydraulic press stands out on its great power, flexibility and major control on energy and movements of the single components.
Conventional Hydraulic System Servo Hydraulic System
Design By combining the quality of our conventional hydraulic production press and replacing the control valves of the hydraulic systems with a servo motor, speed, position and press force are controlled merely electrically. The simple design reduces the number of parts and stabilises oil temperature while facilitating availability and repeat accuracy. Finally the simple design minimises maintenance costs and frequency.
Speed Integrating the force of speed with a servo-motor solution enables extremely fast acceleration and deceleration measured up to 3 times faster than a conventional hydraulic press. The high speed facilitates not only significantly shorter cycle times, yet also improves process control and overall performance stability.
Energy savings up to 70%Facilitating high speed and extremely short cycle times, the servo-motor solution distinguishes itself by reducing energy consumption with up to 70%, depending on the application.
High energy savings are achieved primarily by:
Regenerates fall-energy from ram approach
Main motor stop for every completed stroke (no idling)
No energy loss by deep drawing with passive cushion (single acting die cushion)
Reduced cooling of the hydraulics
Comparative Model - Hydraulic vs Servo vs Mechanical
Well Tested TechnologyWhile the SERVO-hydraulic press is a new product to STENHOJ, the high-quality components and combined technologies deployed, are familiar and well tested. Thus, underpinning the new SERVO-hydraulic press technology, we use the same quality parts, components and electrical cabinets as for our well known hydraulic presses, while the construction of the hydraulic system still offers the same options for pressure control as our conventional hydraulic press.
Finally, we have deployed decades of experience with advanced pump systems and expertise from more than 150 advanced electro-mechanical broaching machines with equivalent servo-motor system to the design of the press.
By combining the best of two worlds the SERVO-hydraulic press from STENHOJ is a strong and competitive choice for modern production.
