Skyscraping adhesion – plasma technology ensures airborne radio electronics
The South German company Rohde & Schwarz – a global market leader in wireless communication systems – uses Openair® plasma to ensure that the protective coating applied to airborne radio SMDs adheres reliably without damaging the highly sensitive electronics. The trade journal DICHT! ('Sealed!' No. 4 /2016) contains a detailed report.
Strong bond and media-tight: Turnkey plasma unit for injection molding
Automation of the new Plasma-SealTight® sealing process has resulted in a turnkey plasma unit constructed by Plasmatreat, which can be adapted to suit any conventional injection molding machine. The Swiss magazine POLYSURFACES (No. 5/2016) presents the new system.
When the foil fails to stick - Plasma as troubleshooter in touch foil bonding
Bubbles forming in the boundary layer is a dreaded yet familiar phenomenon in foil adhesion: The adhesive bond, despite initially appearing to bond reliably, failed the climatic test at an automotive component supplier. The technical journal DICHT ("Tight", No. 3/2016) has the case study.
Radical change: Instead of using solvents and primer, the South German lighting manufacturer Waldmann is now pretreating his LED surface-mounted machine lighting with Openair® plasma before bonding. In its anniversary issue (No.15 [08-11]/2016) Germany's leading electronics journal ELEKTRONIK-PRAXIS reports on the whys, the hows and the benefits for the producer.
PlasmaPlus®- Coating ensures plastic-to-metal joint in the injection molding process After two years of preparation, Plasmatreat and plastic compounds manufacturer Akro-Plastic have joined forces to launch a new systems solution on the market that not only promises a particularly strong, media-tight plastic-to-metal joint in the injection molding process, but is also corrosion-resistant, environmentally friendly and particularly cost-effective. Read about all the details in KUNSTSTOFFE -International (2016/6-7).
Perfect hold and flawless finish: In-line plasma treatment before painting
There are several types of pretreatment for painting processes, although the use of wet-chemical environmentally harmful substances is still one of the most widely used. But there are alternatives: A pretreatment with atmospheric pressure plasma is not only environmentally friendly, it is also far more efficient, faster and more reliable. IST (International Surface Technology No.2 (7)/2016) has all the details.
Here Comes the Sun - Plasma treatment of a CFRP solar race car
Less mass means less energy consumption. Treating the CFRP body structure of a solar race car with Openair®-plasma resulted not only in a new and much faster joining process but also in saving several kilos in weight. The South African journal SA PLASTICS (2016/6-7) reports on the production process.
Atmospheric pressure plasma makes CFRP solar car lighter For a faster bonding process, optimized adhesion and to save several kilos in weight, the CFRP components of a solar racing car were pretreated with Openair® plasma prior to bonding. The bilingual journal POLYSURFACES (No.3 /2016) reports on the details.
Turn to the Future - Pretreatment of LED Lights with Atmospheric Pressure Plasma
After using wet chemicals for years, a leading south German lighting manufacturer decided to radically change his pretreatment process. Instead of using solvents and primers, the surface-mounted LED machine lights are now pretreated in an environmentally friendly way with Openair® plasma in preparation for bonding. Read the whole case study in ADHESION (No.2 /2016).
Medical Technology: Resistant and non-toxic surfaces created inline
The Institute of Medical and Polymer Engineering at the Technische Universität München, Germany is testing Openair® plasma coatings for biocompatibility. The aim is to develop a coating that is innocuous to cells and tissue and shows optimal surface properties in the human body. KUNSTSTOFFE-INTERNATIONAL (2016/04) reports on the results achieved so far and on future application possibilities.
