Video: Plasma Technology - 100% Made In Franconia
In the crisis year of 2008, the management of bdtronic was faced with the decision to either lay off long-term employees or to find a plan B. Plan B was to use the crisis for the future. So it was decided to create new potential and pillars through diversification and to give the grown team with their know-how and experience new tasks. The new technologies defined in this process are thermal plastic riveting, plasma pretreatment and impregnation of electric motors - all that today's Tier 1 and OEM need. The medium-sized company has therefore been offering plasma technology and complete machine solutions for component pretreatment since 2008, and now also VP4, the variable plasma.

A special feature of the technology of the VP4 is the robust construction and the simple and quick integration: the transformer required for high-voltage generation is no longer a separate module that is connected to the plasma head via a bulky high-voltage cable, but is already installed in the plasma head and potted securely. A 5.5 m long cooling channel runs through the plasma head. The process gas flows through this and thus removes the excess heat generated by the process. By eliminating the high-voltage cable, stable standard power cables of any length with pluggable connections can be used. The power losses resulting from high-voltage transmission are thus minimized.
Integration on multi-axis robots
The total weight remains under 5 kg, so that integration on small multi-axis robots is also possible. The devices are designed as standard modules with standard interfaces and are literally “plug & play”. Another special feature is the variably adjustable performance. This enables the pretreatment of different surfaces in one machine, which is often necessary before gluing or sealing processes. Different materials - such as plastic housings with metal lids - have to be securely, tightly, firmly and permanently connected here.
In software development, particular attention was paid to user-friendly and intuitive operation, the figure shows the "speedometer" with the respective setting and limit values for process monitoring. All in all, this is not just a well-thought-out product design and solid engineering work that BD-Tronic is proud of. The trend to think in many ways was also understood.
Technical center for process simulation
Today plasma processes are considered the state of the art in all applications where a high surface quality and therefore optimal adhesion are necessary. Even though there is now a lot of experience and understanding of the effect and thus the benefit of plasma pretreatment, the first step is usually always in the technical center to define and validate the feasibility and the targeted process parameters. Today bdtronic has nine application laboratories, where daily process simulations and sample productions are carried out under production-related conditions. Various measuring devices are available to check the surface energy, the cleaning effect and the shear strength of the bond.
What is plasma?
Bonding as a cohesive joining method is becoming increasingly important in modern industry. Mixed material connections, complex geometries, new materials, minimized quantities of adhesive, these are all challenges that material manufacturers and plant manufacturers have to face. Plasma for improving adhesion, i.e. cleaning and activating surfaces, has been used here for some time.
Plasma ensures that impurities are removed from the surface and functional groups are created. This leads to several effects: on the one hand, the wettability of the surface is increased so that the applied material can be optimally distributed on the surface. On the other hand, the functional groups form a strong bond with conventional adhesives and potting compounds and thus ensure better, long-term stable adhesion, strength and tightness of the connection.
Secure and firm connection with hot rivets
Plasma is called "4th Aggregate state”, a state in which the universe around us is over 99%. As a physical pretreatment method, plasma is created by applying a high potential difference between anode and cathode. The discharge of this high voltage creates an electric field, which converts the process gas flowing through into the plasma state. If this process happens under atmospheric pressure, one speaks of atmospheric pressure plasma (ADP). ADP is used in industry, for example, when sealing grooves or bonding surfaces of hard-to-bond plastics or contaminated metals are prepared for the bond.
The majority of the plasma devices available on the market are used not only in the pretreatment of surfaces prior to bonding, but also in coating technology, medical technology, painting technology and in many other areas where sufficient and stable adhesion is made possible by plasma.
