Fraunhofer IWES Demo Center
A Demo Center has been constructed within the Fraunhofer IWES facilities in Bremerhaven, Germany. EEW-PROTEC has installed a CNC-controlled production cell featuring two cooperating 6-axis gantries. Each gantry measures 5 x 2 x 2.5 meters and can handle a 400 kg payload for end-effectors. This cell was designed for the following tasks:
- Manufacturing of blade molds with flat back profiles and integrated sensors (a 20-meter section of a 40-meter blade)
- Precut center
- Roving-impregnation and -placement technology
- Automated placement of large precuts and preforms
- Automated in-situ production of core materials
- Direct-infusion equipment
- Automated bonding application
- Surface finishing system
Additionally, a heavy-duty platform with a 4-ton load capacity was installed for material transport during the process. This platform can optionally be electrically connected to one of the two portals and then automatically follows the portal's X-axis movement.

The purpose of the Center es to offer a technology-platform where all Windenergy related tecnologies can be tested on real conditions.
This includes not only the product itself but also the necessary manufacturing processes:
- Industrial hard and software concepts
- Development and validation
- Test specimens and structures
