Friction Stir Welding (FSW) joins two parts with a specially shaped, rotating tool.
Due to rotation and pressure of the tool frictional heat is produced and the parts soften plastically in the area of the rotating tool without reaching the melting point.
The pin of the tool immerses into the malleable material of the parts and produces by its rotation and shape a homogenous blend along the joining line. The shoulder of the tool forms and smoothes the welding line with only a marginal ridge.
After cooling there is a solid phase joint of the two parts. The process does not need filler wire, welding flux or gas shielding and produces a sealed weld without porosity and without inclusions.
For larger series or double-sided decorative surfaces the Resin Transfer-Molding (RTM) process is well suited. Massive closed mold and counter-mold system are used as the resin is introduced under pressure into the mold system.
This process pays off for high quality parts and / or components, which are produced in larger quantities.
Up to 15 meters component length pressable in one single shot!

The highest level of quality assurance!
In our clean rooms, the concentration of airborne particles is kept as low as necessary to produce and test high-precision products for you.
Our autoclaves are used for thermal treatment of fiber composite materials in overpressure range.
The thermal treatment of the substances happen in batches because of the typically occurring sealing against the surrounding atmosphere.
The high pressure inside the autoclave is used to compress the individual laminate layers. Generally, the component is simultaneously evacuated in order to completely remove excessive air from the fiber composite.
ECOLOGICAL TECHNOLOGIES® currently has two autoclaves in operation:
ø 2000 x 6000 mm (6 bar) respectively ø 3000 x 8000 mm (8 bar), with a 24-point respectively 40-point vacuum measuring system and curing temperatures of 180 ° C (standard) up to a maximum of 250 ° C.
