PVT successfully introduced its newly developed PDA* technology. PVT uses the arc – evaporation technology to evaporate refractory metals and alloys for the deposition of hard, wear resistant coatings onto cutting and forming tools as well as components. The PDA* technology enables us to split the magnetically guided arc in many small, extremely fast moving arcs.
The result of this development is, that these arcs are now evaporating the materials, such as Ti, Cr, AlTi, AlCr, TiSi and many others, in a much smoother way, reducing the number and size of the droplets considerably and achieving smoother coatings.
In a number of applications, where extremely smooth coatings are needed for specific requirements, cost intensive post – treatment can even be avoided
* PDA = Plasma Diffused Arc
PVT products and services are presented at countless shows, exhibitions and conferences worldwide to provide our customers with an on site overview of current products and our latest product innovations.
November 27 to November 30, 2019
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.
