The data is exchanged via NX or CATIA native format. We use STEP, Parasolid or IGES for 3D. DXF, PDF, CGM are used for drawings and 2D shapes.
The painting is also part of our services, to relieve you even at this step!
The maximum dimensions of the components to be painted are 3100 x 5200 mm. The air temperature for drying is continuously adjustable up to a maximum of 120 ° C. All coating systems which are suitable for high pressure airbrushing, can be processed.
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!
On our modern presses we manufacture panels and parts with all established core materials and skins of prepreg, aluminum or laminates (HPL and CPL). Our capabilities include 14 presses, with 5 multi-daylight presses and 2 large format presses with 12 meters respectively 15 meters pressable component length.
Since ECOLOGICAL TECHNOLOGIES® manufactures nearly all plastic or composites components for many customers, it became obvious to them to entrust ET to care also for the logistics of accessories and the assembly of the complete component groups– ready for the integration into the final product.

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.
