INNOVATION Short cycle times by close contour heating

Processes can be accelerated through the efficient use of resources. Our textile heating technology pursues precisely this approach. We bring the heat in the process exactly to the right place at the right time.
The combination of textile technology and electrical engineering enables us to produce heating structures with extremely high performance and robustness. The heating structures can be divided into different zones and outputs.
The manifold integration of the heating structures in silicones and fiber composites opens up a broad field of application - on the one hand, components can be directly heated to keep special areas ice-free or to fulfill a comfort function, and on the other hand, production equipment can be created that quickly and in the right quantity introduce heat into the process.
Due to the low mass of the heating structures, very high heating speeds can be achieved. This enables us to reduce the cycle time and save energy at the same time.
Heating speeds of > 50 K/min and temperatures up to 200°C are no challenge for us.

Prefixing and laminating Equipment for the production of high-quality interior components

High-quality interiors in automobiles are standard today. Leather and artificial leather are used to create the haptic and feeling of the interior.
The various decorative materials are laminated and pressed onto carrier components. An adhesive builds the connection between the two components. With the help of our heating technology, the various manufacturing steps can be accelerated and cost-effectively implemented.
During pre-fixing, the sewing dress is pulled onto the carrier component. By using locally heatable component holders, the carrier component can be tempered so that the use of a hot-air dryer is reduced. This allows the working time to be reduced and saves valuable costs. The adhesive is activated and pressed by our Qpoint membranes. These membranes are formed exactly to the geometry of the complex components and thus enable direct heating of the adhesive up to the activation temperature. A great advantage is the three-dimensional adaptability of the membrane. Neither undercuts nor complex structures exclude the use of our membranes. Tolerances of the carrier component from the injection moulding can be compensated by the membrane. In addition to rapid heating of the membrane, our membrane can cool the component and the adhesive to the desired demolding temperature.

Preforming Tools for forming and consolidating of textile products

Each fiber composite component requires a differentiated view for an optimal production method. This is determined by the required quantity, complexity and quality of the component. Our experience in the production of fibre composite components enables us to optimally design this manufacturing process.
Due to the increasing use of dry textile reinforcement structures in the aerospace and automotive sectors for the production of lightweight structures, the demands on preforming are also increasing.
A preform is a textile, non-impregnated, multi-layer reinforcement structure. In a suitable subsequent manufacturing process (VAP, VARI, RTM), the preform is impregnated with a matrix system and consolidated into a fibre composite component. The shape of the preform corresponds to the later component geometry, whereby the individual fibre orientations in the layers are fixed by a suitable binder. Depending on the complexity, a distinction is made between direct and sequential preforming, in which cores or inserts can be integrated.
The use of our technology enables extremely short cycle times due to the low thermal mass of the moulds and an optimal local surface heating capacity. We adapt the solution exactly to your requirements. In this way, your requirements with regard to process parameters such as heat-up and heat-down rates, process vacuum, handling and quality assurance can be implemented holistically.
