The Rexroth concept for successful injection molding machines consists of an A10VSO/A4VSO variable displacement pump and powerful control electronics.June 22, 2007 - Bethlehem, PA - www.boschrexroth-us.com) The SY.DFE provides the ultimate in hydraulic energy efficiency, electronically controlling both flow and pressure with exceptional speed and precision.
A proven combination of a variable displacement axial piston pump of swashplate design and innovative proportional control electronics, the SY.DFE provides efficient, reliable controlling of the pump. The SY.DFE was launched at the plastics processing trade fair in Düsseldorf in 1989, and with 100,000 units installed, it demonstrates the exceptional value it has provided in multiple plastics processing applications since its debut. Primarily used in injection molding machines, the system is based on a Rexroth A10VSO or A4VSO axial piston pump.
By adjusting the pump’s swashplate, flow and pressure can be infinitely varied, and the required flow and pressure can be generated fast and accurately for specific machine functions.In addition, functional sequences in an injection-molding machine can be precisely controlled with the help of the SY.DFE. The flow control works without pressure losses in the power branch, which significantly increases the hydraulic efficiency within the machine. Moreover, the total efficiency of the machine is increased due to the high repeatability of the control.
Rexroth offers this system in three versions: SYDFE1 with external closed-loop control electronics, the SYDFEE, with analog, integrated functions, and the SYDFEC, which offers integrated, digital closed-loop control electronics and the optional field bus controlling via CAN, so that users in the plastics processing industry can benefit from a proven plug-and-play system. Bosch Rexroth AG, part of the Bosch Group, achieved sales of approximately $6.2 billion (4.9 billion Euro) in 2006 with over 29,800 employees. Under the brand name of Rexroth the company offers all drive and control technologies, from mechanics, hydraulics and pneumatics to electronics and associated service.
Over 500,000 customers worldwide utilize Rexroth’s unique technological know-how to implement their innovative and future-oriented systems and machine concepts. The global player, represented in over 80 countries, is an extensive supplier of components and systems for industrial and factory automation and mobile applications.
