    Design and technology come together with many benefits that are equally important for you as a company and your customers. The combination of design and technology makes it possible to create products and services in such a way that they provide a consistent and perfect user experience. Ultimately, we are dealing with an aesthetic, modern and user-friendly product that increases customer satisfaction and thus customer loyalty to your company.
    The advantages of combining design and technology:

    • Promotion of innovations:
      The integration of design and technology makes it possible to develop the latest solutions that surpass the previous ones. Technology experts and designers can work together in perfect teamwork to create new creations and thus products that leave the competition far behind.
    • Sustainable and effective development:
      The combination of design and technology from the outset makes it possible to recognise and avoid conflicts and contradictions at an early stage. This leads to tighter and more targeted development work and shorter cycles, as possible rework and the associated time expenditure are prevented.
    • Emotional ties to products:
      Professional design can create intense emotional connections to products. The combination of this emotional level with sophisticated technology results in stronger customer loyalty and a pronounced loyalty to the brand.
    • Integration of aesthetics:
      With our sophisticated and aesthetic design solutions, we make it possible to integrate technical devices or systems into their surroundings. This is also important for heating systems to ensure that these sometimes very complex systems can be perfectly integrated into their surroundings.
    • Stand out in the market:
      Products should be technically sophisticated and have an attractive design at the same time. This increases their chances of standing out from the multitude of competitors. Clear differentiation on the market makes it possible to significantly increase the importance of a product or brand.

    Production techniques

    Galvanised plastic parts can be used specifically to make your product even more elegant by using real metal and, thanks to their low weight, also enable excellent integration into the respective functionality.


    Plastic injection moulding

    Hübner-KTB produces components precisely tailored to the customer's needs using 1K, 2K and 3K plastic injection moulding processes. We advise you individually and offer you the best possible solution, taking into account all technical and economic aspects.

    Laser technology

    Laser technology

    With our sophisticated laser technology, we process the parts prepared by electroplating in such a way that neither a chrome nor metal layer is created in existing symbols during the final coating. This enables us to create extremely fine symbols as well as lines and high-precision labelling that can later be X-rayed.

    We give loose granulate a functional shape.
    Hübner-KTB Oberflächentechnik GmbH produces components to customer specifications using 1K, 2K and 3K plastic injection moulding processes on over 6,500 m² at two sites with well over 50 plastic injection moulding machines in the clamping force range up to 6500 kN.

    Our systems are fully automated and usually equipped with camera systems to monitor component quality.
    The degree of automation is sustainably increased by highly efficient CNC handling systems.

    Injection moulding with up to three components enables Hübner-KTB to produce a wide range of multifunctional parts from variable plastics. Following an individual consultation, we can offer our customers transfer, core-back or index technology for the 2K and 3K process with a view to economic and technical aspects.

    Granulate pre-drying and central granulate supply, tool maintenance by our mould making department and, last but not least, careful measurements to determine quantity and quality ensure the required process reliability and virtually constant machine running times.


    • 3-shift operation
    • Consistently high product quality
    • Checks during the process
    • High degree of automation
    • more than 50 plastic injection moulding machines
    • ABS material, ABS/PC material



    Our plastic electroplating facilities are state of the art and ensure the surface finishing of plastic raw parts made of ABS or ABS-PC. Hübner-KTB has many years of extensive expertise in the electroplating of plastic parts for both interior and exterior applications with various chrome surfaces (high-gloss or matt in many degrees of gloss). Electroplating with metal layers gives the surfaces an attractive appearance, strong scratch resistance, a more stable bond with high heat resistance and the best protection against static charging, electrical interference (shielding) and the effects of UV light. Due to the different requirements, surfaces, geometries, etc., there is a separate processing programme for each article, which is entered into the control system of the electroplating machine.
    As a company, we are a member of the Fachverband Galvanisierter Kunststoffe e.V. (FGK) and pay careful attention to the handling of all incoming and outgoing resources.

    All relevant process baths are extracted in our electroplating systems. The exhaust air is then cleaned 100 per cent in the designed exhaust air system, which was built according to the latest technical and chemical standards. We verify this functionality with continuous monitoring measurements.
    Thanks to our ultra-modern water treatment systems, the waste water produced in rinses and process baths is converted back into pure water. After these processes, each batch of water is assessed in a final check and only released if it fulfils the high specifications. We use external laboratories and the relevant authorities to check these analyses.

    As a recognised surface coater, Hübner-KTB Oberflächentechnik GmbH offers the best of two technological processes – the “electro-chemical” process and the “physical vapour deposition” process.
    PVD and plastic electroplating offer the greatest possible variety of combinations with all the important advantages for an excellent, long-lasting and visibly high-quality surface. The PVD process helps with the direct coating of plastics.
    Be it germ or allergen-free surfaces, abrasion and scratch-resistant and even splinter-free surfaces: our PVD process optimises the surface properties of a product many times over.
    The complete process service including comprehensive advice, precise layer analysis and layer development plus laser engraving forms the perfect basis for an extensive range of colours and the best surface qualities thanks to our in-house PVD coatings without compromise.

    We ensure an all-round successful finish for your quality products.

    Components pre-treated in electroplating are further processed in our laser production. In this way, we prevent a layer of chrome or metal from growing in the desired symbols during the final coating process. This technology makes it possible to produce even the finest symbols, lines or very precise labelling that can even be seen through in night-time design. Our hidden line process is another customised production process. It is used to create structures that are almost invisible during the day and yet shine through in the dark. We use partially and fully automatic machines for this, which are subjected to permanent quality monitoring by camera inspection. We can produce labelling panels up to a size of 600 mm x 600 mm. We have 5 laser systems, 2 precision lasers and 2 fully automatic machines available for production. Several laser technologies and applications are protected by our own patent and utility model rights.
