Fully automatic Vacuum Infusion Process for the Casting of Rotor Blades

Environmentally friendly wind energy systems are the to-date most cost-efficient renewable energy source with excellent potential for growth in the booming market of the alternative power generation. Whether on-shore or off-shore, tough and reliable technologies are in demand enabling the users to gain maximum profit and safe returns.
Most diverse equipment sizes and specifications require not only mature design concepts but also the continuous development of equipment components and their necessary manufacturing techniques. This also includes composite components that are processed on fully automatic vacuum infusion systems developed by HEDRICH. For example for the casting of large rotor blades under permanent vacuum, which besides other benefits avoids a quality-decreasing enrichment with gases.
