Our components for pneumatic vehicle suspension

For spring system with level control

At Schröder, we know the high loads that suspension components are exposed to. And yet we still manage to reduce the use of materials, simplify production processes and guarantee quality. Transparent and seamless.

We would be happy to talk to you—of course without any obligation!

Components, technologies, processes

Air suspension by Schröder

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.

Leak test

Helium is non-toxic and does not react with other materials. The ‘small’ gas molecule is inert and can therefore be used safely without reacting with any of the materials inside the part being tested. The small atomic radius enables fast testing and detection of even the smallest leaks. We also use a recovery system to reduce costs.

Assemblies

We offer the entire package from the first simulation to series production and assemble the vehicle suspension components largely fully automatically. Following injection molding of the complex multi-chamber air suspension pots, we screw together Voss fittings, assemble connecting pins after pre-heating, join housing halves using hot gas welding, label components – and carry out close-meshed product testing during production.

Retrievability of production parameters

Complete traceability and protection against liability claims: Lasering a data matrix code has long proven its worth. 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.

Our technologies

Metals, plastics, automation

icon
Plastics

For components with an impact on ride comfort, plastics play a key role. They are optimally designed in terms of their application and processing properties and combine complex geometries with optimum mechanical and thermal properties, for example.

icon
Metals

Inserting metal components into the injection molding process is our bread and butter. In our own stamping shop, we produce precisely fitting metal inserts and outserts, which we then feed into the mold fully automatically in the same way as standard components.

Automations

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

Our know-how, our technologies

From the granulate to the assembly

As a member of the international OKE Group, we develop and produce components and sub-assemblies for thermal management applications. We currently use the following technologies at our site in Herscheid:

  • Plastic injection molding
  • Metal-plastic hybrid process
  • Joining processes such as ultrasonic welding, UV welding, laser welding and hot gas welding
  • Assembly of complex components made of metal and plastic parts – ready to build!
