Information

PVT (Harbin) Coating Co.,Ltd. was established in 2004 by PVT Plasma und Vakuum Technik GmbH (in short: PVT GmbH) from Germany. PVT Harbin is the most advanced PVD coating center in the Northeast of China with all equipment, such as cleaning line, pre- and post treatment, test and measuring equipment all from Europe. All coating equipment was delivered by PVT GmbH.


PVT GmbH is a leader in the field of ion- and plasma-assisted vacuum coating technologies. It designs, develops and manufactures PVD vacuum coating equipment and develops coating processes and coatings.

PVT’s world headquarter is located in Bensheim, just about 50 km south of Frankfurt, Germany. PVT GmbH is running all its Chinese operations out of PVT Beijing, its Chinese headquarter.

PVT GmbH started PVT Harbin as its first coating center in China. By now additional 4 coating centers followed in Dongguan, Qingdao, Wenling and Taicang. All the centers work with the most advanced equipment from Europe and provide efficient and high quality coating service for all their customers.

Since 2004 PVT Harbin provides the customers with the highest standard of coating service and delivers the most advanced high – performance coatings to boost their productivity with innovative solutions. Many major companies have appointed PVT Harbin after excessive testing and evaluation as their leading coating provider, such as Harbin Dongan Auto Engine Co., Ltd., Harbin Dongan Automotive Engine Manufacturing Co., Ltd., Harbin No.1 Tool Company, Changchun First Automobile Works, Harbin Measuring & Cutting Tool Group Co., Ltd., Mudanjiang Tool Co. Ltd. etc.

Consistent high quality service paired with unrivaled coating quality and impeccable customer service qualified PVT Harbin for many customers to be their preferred supplier.

PVT’s coatings are widely used in the cutting tool industry for dies & molds, in the aircraft industry, for medical and automotive applications.

Such coatings are among others TiN, TiCN, CrN, AlTiN, AlCrN, TiSiN, AlTiSiN, AlCrTiSiN as nano-structured single or mulilyers. Their main functions are wear resistance, erosion resistance, corrosion resistance and reduction of coefficient of friction.

All such coatings with typical coating thicknesses from 1 – 5 µm, sometimes even significantly thicker, can improve the lifetime of the tools and components many times.

The ultimate goal of our companies is the “total satisfaction of our customers”.

Trade Shows

News


  • 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.
