We have been working with metals for over 100 years – and with the combination of metals and plastics for many decades. Our experience with this combination of materials forms the basis for the production of components for thermal management. This is because hybrid construction methods, for example in thermoplastic sandwich composites, require knowledge in the processing, but above all in the combination of metals with plastics that meet the requirements.
With our interdisciplinary expertise, we adapt individual components of cooling, heating and air conditioning subsystems to create an efficient overall system. For perfect temperature control in every area.
We would be happy to talk to you – even without obligation! – to talk to you.
Metal-plastic hybrids are popular across all industries. Today, around 60 percent of all metal stampings are directly or indirectly joined with plastic. And there are good reasons for this! Intelligent metal-plastic hybrids are created by taking into account value-adding ideas or after a precise analysis of the potential added value, and our customers benefit from the advantages of these hybrids. Above all, these components are characterized by functional integration in combination with high resilience.
The coolant architecture of electric vehicles is very complex with its multi-layered circuits for interior heating, the battery and on-board electronics. The installation of heat pumps increases the range of electric vehicles on the one hand, but also the complexity of the temperature systems on the other.
The combination of different materials, assemblies and intelligent integration of functions in a component is essential here – we know our way around these processes!
In addition to direct connections by overmoulding inserts, we also use downstream processes – often with a high degree of automation. These range from classic punching, UV, ultrasonic, hot gas and laser welding to automated assembly with robot technology.
The ‘coolant changeover valves’ control the coolant in off-line cooling circuits of the drivetrain and in the heating circuits of vehicle interiors. The geometrically and functionally demanding components require a great deal of expertise in mold technology to ensure clean and efficient production from granulate to demolding.
We make this knowledge and the integration of electrical and hydraulic connections to the valve body available to our customers.
We overmold electrical contacts and shafts with hard or soft plastics. The different expansion coefficients between metal and plastic are particularly sensitive in these components with low tolerances. This is because even the smallest errors can cause liquid and gaseous media to penetrate between the metal and plastic due to capillary action – resulting in leaks and corrosion.
We use special test procedures for highly resilient and safety-relevant components. One example is the burst test, in which a sealable housing is tested for tightness and pressure resistance. These procedures are also often very useful for welded parts, such as hydraulic connections.
Coolant pumps are an example of components with high efficiency, low weight, compact design and a long service life. And all this in an environment with high vibrations and a temperature resistance of up to 140° C. We also meet these requirements through careful production, with 100% traceability and camera inspection if required.
We also produce high-performance, robust components for the engine compartment. Whether for classic combustion engines, battery electric vehicles (BEV), hybrid electric vehicles (HEV), plug-in hybrid electric vehicles (PHEV) or the further development of new drive models such as fuel cell electric vehicles (FCEV): We are happy to work on your new developments and make our expertise available!
Seamless traceability and protection against liability claims: Lasering a data matrix code has long proven its worth for us and our customers. In contrast to one-dimensional barcodes, ‘DMCs’ require less contrast for machine readability and are more error-tolerant. This method is particularly suitable for sensitive, safety-relevant thermal management components. During assembly, we assign codes for each individual part as well as for the final assembly.
