A wealth of options

Welding technology
Junior Kühlkörper uses modern robotic welding systems to join together  extra-wide extruded sections.
Our expert welding shop has DIN EN 15085-2 certification and is therefore approved to weld railway vehicles and components.

Powder coating
To provide optimum protection against dirt and corrosion for top quality precision components, we can apply a powder paint coating on request.
In comparison to liquid paints, powder coatings guarantee high abrasion resistance to ensure that your products enjoy a long service life.
They are highly resistant to mechanical stress and can withstand even hefty impacts. Powder coatings are free of heavy metals and solvents and are
therefore particularly eco-friendly.

PU seal
We use state-of-the-art technology to expand a special polyurethane seal directly into the recess of the component. This allows components to be
modified as required for their flow properties, reactivity and colour. It also improves protection against moisture, dust and other harmful effects.
The seal makes an excellent adhesive bond with the component and demonstrates outstanding long-term behaviour, making it ideal for industrial
components in permanent use. The material can be applied in 2 and 3-dimensional form. Heat sinks of all shapes and geometries can be
sealed using polyurethane foam.

Assembly
Where the cooling ribs of a heat sink are arranged too densely to allow them to be produced by applying the extrusion process, they are glued onto the base plate manually. Furthermore, we offer a wide variety of assembly work – for example, pressing in threaded bushes and spacer bolts and assembling active cooling elements.
