Plasma Technology can help start ups to improve their process and product quality

The article by Marketing Manager of Relyon Plasma, Andrea Werkmann, describes how PZ2 and PZ3 handheld plasma devices can help start-ups to improve their product quality. 

Machinery and Plants Interdisciplinary Industries - The use of plasma technology to optimize adhesion processes are state of the art in the industry. However, since conventional plasma systems rely either on cost-intensive vacuum chambers (low-pressure plasma) or a relatively high degree of automation (atmospheric-pressure plasma), smaller companies or start-ups can benefit less from the advantages of the technology.

Thanks to relyon plasma’s piezo technology, professional adhesive joints are possible without major investments. Technologically, the plasma generation is based on the discharge of the piezoelectric transformer CeraPlas™ from TDK Electronics AG, which is built into the cold plasma handheld device piezobrush®. This enables highly efficient plasma generation at a power consumption of only 18 W. Different surfaces can be activated with the module Standard (left Fig.) for non-conductive materials, while the module Nearfield (right Fig.) is used for the treatment of conductive materials. 

For special geometries, the piezobrush® PZ2 can also be equipped with a multi-gas nozzle, whose needle insert allows treatment in narrow grooves and the injection of other process gases.

Advantages:

• Materials such as plastics and composites, which could otherwise only be securely bonded, sealed or encapsulated by pre-treatment with toxic and environmentally harmful chemical primers, can now be optimally processed.
• The highly reactive molecules in the plasma gas functionalize the surfaces, thereby increasing wettability and creating anchor groups in the uppermost atomic layers, which in turn form an optimized bond with adhesive, sealing or casting compounds.
•  Compared to conventional systems with about 100 times the power consumption, the piezobrush® can achieve similar actuation results on a variety of plastics at a process speed that is only 10 times faster (about 20 mm/s)
