The customersof this business area are predominantly found in the woodworking, furniture,construction and energy industries 4.

The composites division is involved in processes, pressesand fully automated production lines developed and realized for the productionof light weight fiber reinforced plastic components. Most of the customers arefrom the automotive and supplier industry 4.The recycling division focuses on development of completerecycling plants for treatment of different waste materials through mechanicaland biological means for the extraction of secondary raw materials or energy 4.2.

2 Press TechnologyThe composites division specializes in the development ofpress systems available in standard and high-accuracy variants with or without activeservo-controlled parallel motion systems. The presses are designed by keepingin mind the requirements of the plastic and composite forming industry.Depending on customer requirements, Dieffenbacher is able to supply suitablepress systems with process-oriented controls 4. Figure 2 Dieffenbacher PressTypes 4There are currently three different press types:1.    Dieffenbacher Compress Lite (DCL)The DCL press type is available in an upstroke andshort-stroke design with a low overall height and an energy-saving drive.

Thebevel deflection line provides an even bend progression of the upper and lowerdie. The high-precision parallel motion behavior ensures a consistent componentthickness and increases the quality of the components. The Lite concept providesexceptional flexibility and rapidness in die changing due to its 4-sidedaccessible design.
