Components for
thermal management

Cooling, heating, shielding

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.

Thermal Management by Schröder

Cooling Fluid Control Valves

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.

Contacts and shafts

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.

Breakage and burst tests

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.

Electric Coolant Pumps

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.

Powertrain

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!

Transparency and traceability

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.

Metals, plastics, automation

Plastics

For components with an impact on thermal management, plastics that are optimally designed in terms of their application and processing properties and, for example, combine thin wall thicknesses with sufficiently good mechanical properties play a key role.

Where possible, we use readily available standard plastics. For thermal management components in special temperature ranges, however, we primarily use materials that are specially tailored to the application and whose application and processing properties are optimally designed.

Metals

Inserting metal components into the injection molding process is our bread and butter. In our own stamping shop, we produce the precisely fitting metal inserts and outserts, which we then feed into the mold fully automatically. We also consider direct thermal joining when planning series production. In this approach, the metal component and the pre-molded part are heated separately and welded together, for example based on induction and using ceramic high-rate heating elements.

We can also carry out pre-treatment techniques such as laser structuring and plasma processes to increase the bond strength through close interlocking of metal and plastic.

Automation

Due to the miniaturization of electronic components, the need to increase efficiency and the increasing quantities of highly integrated functional components, cost-effective manufacturing processes are more in demand than ever.

We are characterized by our ability to handle complex, multi-layered production processes. This skill is crucial to the success of efficient series production of combined hybrid components. Even highly integrated functional components are efficiently manufactured by us in fully automated production and testing processes.
