Energy-efficient production with DIEFFENBACHER Energy savings in the production of high-quality composite components with adaptive accumulator management and short- stroke presses

Rising energy costs have composite manufacturers worldwide focused on energy-efficient production. With its press series featuring a short-stroke closing system and adaptive accumulator management, DIEFFENBACHER, a supplier of complete composite systems, offers
customers proven solutions for saving energy.

DIEFFENBACHER short-stroke presses are designed for minimum energy consumption, high press forces and short cycle times. Presses close with small cylinders until just before the position where forming takes place. Thereafter, large cylinders act with the corresponding press force. This makes it possible to reduce the oil volume by 88% compared with conventional concepts. Additionally, the DIEFFENBACHER closing system allows individual programming of the starting position of the forming. The result is high flexibility as well as large opening heights and good accessibility for parts handling.

Adaptive accumulator management optimizes energy consumption by automatically determining during the first press strokes the exact energy required for forming. For subsequent production cycles, the hydraulic drive accumulator is charged only to the corresponding required pressure level. All settings are determined automatically by the machine control system, reducing the load on the machine to a minimum.

Through the short-stroke closing system and adaptive accumulator management, DIEFFENBACHER customers increase the energy efficiency of their production and avoid unnecessary system losses during pressure relief after forming, significantly reducing cooling water requirements.

“Sustainability is important to our customers, and energy reduction is a key component of sustainability,” explains Marco Hahn, Sales Manager of the Forming Business Unit at DIEFFENBACHER. “In addition to short-stroke presses and adaptive accumulator management, we have many other ideas for saving energy and resources. Every day we work with customers
to develop customized concepts that increase the energy efficiency of their composite plants.”
