Double-walled precision and complex shapes
In the exhaust system, lightweight construction is subject to the toughest of tests. The fischer group has demonstrated again and again how precise air gap insulated double wall constructions can be manufactured that can withstand environmental conditions at any time. The precisely fitting exhaust damper housing is one of the best examples of this.
DHowever, even the most complex designs, such as hydroformed manifold parts or common connectors such as ball head, Torca and V-board connectors, document the range of components made from fischer tubes already successfully in use.
Tail pipes, funnels and Y-tubes show the extreme reshaping of high-temperature-resistant parts that can be realized.
Robust structural parts with hydroforming
Hydroforming has also opened up new horizons in the area of structural parts for automotive applications. Whether crossmembers or longitudinal beams, you benefit from the unlimited range of hydroforming shapes, with which a variety of secondary shaped elements can also be integrated. This results in individually developed chassis structural components that are optimized for both strength and weight.
On various presses with up to 12,000 tonnes and a table size of up to 2.8 x 6 meters, the fischer group offers plenty of possibilities even for larger structural components.
Lightweight construction and economy combined
Components close to the engine mainly include exhaust gas recirculation cooler housings. Here the fischer group has shown how lightweight construction can be implemented economically with small subassemblies, from inner winglet tubes to housings with a variety of shapings and prefabrications.
In thin-walled stainless steel, even visually appealing, heat-resistant charge air pre-tubes ensure a first-class look in the engine compartment with low weight.
Constructive safety built in
Tank systems must reliably store and transport fuel at all times. At the same time, they must provide adequate ventilation – while meeting the highest safety requirements. Even in an emergency, the sensitive area must not pose any danger. For this purpose, fischer tubes with and without metal bellows have proven to be extremely reliable. This applies to flexible or rigid filler necks as well as to flexible tank ventilation tubes.
For this purpose, the fischer group has produced pre-assembled multi-part components as tank inlets or filler necks. Another contribution to process efficiency in later final assembly.
High-precision thermal management
With electric drives the right cooling plays a decisive role. In the coolant circuits, movable and static parts must be hermetically sealed from each other. The fischer group's stator and rotor sleeves perform precisely here.
With often only 0.2 to 0.3 mm wall thickness, the sleeve families for coolant pumps are extremely thin-walled. Their diameters usually range between 20 and 50 mm.
