Our ventilation and air conditioning systems for cars

Gearwheels in combustion air drives optimize the combustion process in the engine by regulating the supply of air accurately and reliably. Their precision design guarantees a high level of performance and improved fuel efficiency. Our gearwheels are designed for use adjacent to the engine:

• High temperature resistance
• High mechanical strength
• Maintenance-free
• Low weight
• Precision production
• Cost-optimized production

Our gear components allow for continuous, maintenance-free operation in installation spaces that are difficult to reach. We design gearwheels for your specific vehicle model, produce the complex injection molds and manufacture your systems in an efficient mass production process.

The flap actuator on the radiator regulates the supply of air to the engine compartment. A precise, needs-based supply of air optimizes the aerodynamics of the vehicle and helps to reduce fuel consumption. As the engine warms up, these movable flaps also help to increase the engine temperature more quickly. Our wheelsets have the following advantages:

• Low weight
• High weather resistance
• Precision production
• Optimal structural stability
• Economic production

The fail-safe function integrated into our wheelsets will ensure that the engine will still cool even if the actuator fails. The plastic wheelset thus contributes overall to the ecological and economic benefits of the vehicle.

Fan impellers distribute air-conditioned air throughout the vehicle interior, playing a vital role in making it more comfortable and pleasant for passengers. By combining plastic and metal in one hybrid component, we can achieve a significant reduction in weight. In turn, this contributes to the overall lightweight de sign of the vehicle and also offers the following advantages:

• Effective heat insulation
• Outstanding vibration damping
• Reduced risk of corrosion
• Long service life
• Low weight
• Economic production

Plastic is a material that not only reduces component weight but also gives us a large degree of freedom in their design. This allows us to precisely customize our components to the challenging geometries and limited installation space in a vehicle. Metal inserts ensure that the parts are extremely robust. They are already inserted ready for the plastic injection molding process and bind strongly with the surrounding material. This creates a homogeneous bond and a composite that offers the advantages of both materials in cooling system applications.

We combine our expertise in plastic injection molding with the development expertise of our sister company, Framo Morat, to provide customized designs for gear components as well as the development and manufacture of complete systems. The custom-designed plastic housing securely encloses and seals the fan motor and all electronic components. Inside the assembly, overmolded metal shafts serve as bearings for the gears. This ensures a robust and highly precise center distance, guaranteeing reliable gear operation across the entire temperature range from −40 °C to +90 °C. The Franz Morat Group’s scope of services includes:

• Adopting your specifications
• Developing the transmission system
• Designing the gears
• Design of injection molded parts
• Production and evaluation of prototypes

We at F. Morat will then handle the production for you. Our in-house skills and expertise for tool construction and precision plastic injection molding in combination with our subsequent assembly and further processing services provide a solid basis for the series production of complex assemblies.
