This "build-to-order" Shuntec-A02 PRO 4-post 4-platen 20-ton servo-hydraulic double action deep drawing press was recently designed and built for a customer from Canada. The application of the press is for deep drawing and forming the aluminum and stainless steel elbow for metal jacketing systems. The servo-hydraulic deep drawing presses feature a 4-post 4-platen frame structure, with a separated machine body and servo-hydraulic control unit. With the built-in load cell, position transducer, and 10-inch HMI, the press brings our client the ability of precise closed-loop control for pressing force and position of the main cylinders. In order to separately control the blank-holding pressure at multiple points of the product during the deep drawing process, we have designed the blank-holding system with 4 lower blank-holding cylinders, with which the blank-holding force of each lower cylinder can be set and adjusted separately. All parameters of the double action deep drawing press including tonnage, stroke, daylight, and bed sizes can be customized to best meet your requirements.
