CHINAPLAS 2010 – Assuring quality with plasma
This year again, Plasmatreat exhibited at Asia's largest plastics trade fair, the Chinaplas 2010, in Shanghai. The Federal Ministry for Economy and Technology had invited export-oriented German companies to join the joint exhibition taking place under its auspices in the German pavilion.
The this year's exhibition with its motto 'Green Plastics - Sustainable Development of Environmentally Friendly Technologies' provided the environmentally friendly Openair® plasma technology with an ideal platform. Apart from representatives of the white goods, packaging, medicine and construction industries, it were above all the visitors from the automotive and electronic industries who consulted Calvin Chen (Director at Plasmatreat China) and his team for information on the most recent Plasmatreat developments and applications.

- Two generators of the 5000 series which had been on show met with great interest. The FG5001 is a space-saving unit that is specifically developed for laboratory fields of application and can be equipped with up to two jets. The FG5002 in turn is a powerful industrial generator incorporating elaborate features such as HMI (Human Machine Interface), an integrated fully automated process monitoring, and a disruption factor analysis characteristic. All the generators of this series not only excel by their elegant industrial design but also by their capability of keeping the plasma absolutely constant even in the case of current fluctuations.
- As to the topic of 'adhesion issues' it could be demonstrated that Openair® plasma pre-treatment not only affords optimal adhesion for the most varied plastics materials in the subsequent bonding process but also provides clear quality assurance.
- The pre-treatment of even large material surfaces created another focus of the trade fair appearance. The presentation of the RD1010 rotary jet coming up with a treatment width of 100mm was deemed representative of the series-connected jets designed for the pre-treatment of large technical foils or panel faces.
- The high degree of water wettability of plastics materials after plasma treatment could be experienced by the interested visitors themselves in a self-conducted test. To this end a piece of plastics material about the size of a credit card, was sprayed with plasma in a partial area in order to activate it. A subsequent water spray test immediately displayed the resultant effect: the creation of a homogeneous water film in the plasma-treated area, and the formation of single water drops in the untreated area that was still left with the too low surface energy.
