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—of course without any obligation!
For applications with high thermal, mechanical, and electrical requirements, we process engineering plastics and high-performance polymers such as PEEK, PPS, PESU, PPSU, PA66, PBT, and other specialized compounds. Our typical tasks include evaluating materials with respect to their
as well as compliance with additional requirements for high-voltage systems, such as defined clearances and creepage distances, low water absorption, resistance to aging under electrical stress, and other application-specific specifications.
We manufacture components of the high-voltage safety concept—such as this connector with a locking mechanism—using fully automated assembly lines. Another notable feature is the wide range of variants available for various cable cross-sections.
We can connect our corrugated tubes using laser and ultrasonic welding processes to fit connectors, quick-connect couplings, coolant manifolds, brackets, or valve housings.
For connectors, we use fuel-resistant PA12-GF30 to ensure high mechanical strength, excellent resistance to media, and reliable performance even under thermal stress.
For PESU, we meet the high requirements for tool steel and hot-runner systems, as well as the longer heating times and high thermal stress on the tools at melt temperatures of up to 400 °C. However, the material is particularly indispensable for the ground functional surfaces of control pistons.
Using insert and outsert molding processes, metal components from our in-house stamping shop are equipped with efficient additional functions. We integrate fastening and guiding elements, provide electrical insulation, and ensure defined creepage and clearances directly within the component.
Within the OKE Group, the Hörstel facility brings together a wide range of expertise in extrusion. This is where semi-finished products such as tubes and profiles are manufactured; we then complete them through thermoforming, finishing, and the assembly of connectors.
As part of the international OKE Group, we develop and manufacture components and subassemblies for thermal management applications. At our facility in Herscheid, we currently use the following technologies:
