News

  • The new xPro4R – HiPIMS V+ meets Rotatables
  • Launching the xPro4C
  • 2017 – a year with challenges

    Delivery and installation of complete turnkey-coating centers. Participation at more than 20 exhibitions and shows in different countries: IMTEX in India, EMO in Hannover and DMC in Shanghai, just to name only a few.
    Four events stand out and deserve a closer look:

    1.  xxl6.5 – The Heavyweight

    The biggest coating system ever built by PVT, has been in China now for 12 months and has been in operation ever since without any problems.

    Key data – for your information
    • total height of the machine: 4.200 mm
    • coating chamber for parts up to 3.000mm coating length
    • designed for substrates with up to 450 mm in diameter
    • designed for substrates with up to 3.000 kg weight

    Our client reports satisfaction with the system and due to the in-house coating facilities a significant increase in turnover and  a rise in market shares.
    PVT will support this business partner strongly in the future.

    2.  A new location – PVT Qingdao

    After PVT Germany took over 100% of the shares of PVT Shandong in Linyi the business was moved to Qingdao. New address is the ‚Sino-German-Eco-Park- Qindao (see photos) , a prospering Industry Park that includes many German businesses in the meantime.
    The ‚Sino-German-Eco-Park Qingdao‘ became known due to the commitment of the  German soccer club FC Bayern München to establish a soccer training school there. 
    The consulting board includes authority figures such as  Klaus Schlappner, a famous soccer dignitary  and well-known former coach of the Chinese national soccer team.

    Soon after PVT Qingdao began coating operations the machine park was expanded and now includes a very efficient plasma-nitriding system. The dual chamber system has vacuum chambers of 1.000 mm in diameter and an effective height of 1.700 mm.

    The PVD coating capacity will be increased by 200% at the beginning of next year, i.e. after the Chinese New Year Celebrations.

    3.  CLS Technology

    At the beginning of the year PVT got an order to develop a highly productive batch-coating system for the deposition of optically dense and highly reflecting metal coatings (CLS technology).

    The client will deposit these coatings on bulky pre-painted automotive components.
    The internal dimensions of the coating chamber amount to a diameter of 1.800 mm and a height of 1.200 mm. PVT successfully reduced the cycle times of 12 minutes requested by the customer ( including loading and unloading) minutes by 25 %.  Now, every 9 minutes coated substrates leave the coating chamber, much to the delight of the client.

    The coating system is currently on its way to China after a successful process simulation.

    4.  HiPIMS and Sputtering of diamond-like carbon coatings (DLC)

    Midyear PVT decided to develop the first own industrial HiPIMS/Magnetron  Sputtering system. The solid basis to that were the preceding very successful process validitations . 
    The introduction of this product will probably take place already in spring 2018.

    Thus PVT is worldwide the only company to use large rectangular sources for all its processes: arc evaporation, magnetron sputtering and HiPIMS. 
    The applications of these  are the areas where erosion- and corrosion resistant, wear resistant and tribological (low-friction) high-performance coatings are needed for cutting tools, dies and molds, components and wear parts.

    PVT will keep you posted.
