Success Story with Linamar GmbH
Plasmatreat GmbH, a specialist in atmospheric pressure plasma technology, and the automotive supplier Linamar GmbH have implemented an automated system for the inline corrosion protection of battery housings in the production process. A state-of-the-art plasma coating system has been integrated into the production process of a premium car manufacturer. By working closely together, the two companies have succeeded in combining pioneering plasma technology with automation expertise to significantly improve the corrosion protection of battery housings in electric vehicles.
Corrosion protection is critical for automotive and battery manufacturers to ensure the durability and safety of their products. Material combinations such as aluminum and magnesium, which are increasingly used in lightweight construction, are particularly susceptible to corrosive infiltration. Traditionally, battery housings have been protected by manual processes such as waxing or electroplating. However, these processes are costly, polluting, have limited process control, and can be logistically challenging.
Innovation against corrosion: Integrated plasma coating system
Plasmatreat GmbH of Steinhagen in North Rhine-Westphalia, the world's leading manufacturer and developer of atmospheric pressure plasma systems, has teamed up with automotive supplier Linamar GmbH, part of the global Linamar Corporation, to find an efficient and environmentally friendly solution for this process for their joint customer: A plasma system integrated into the existing fully automated production line uses Plasmatreat's PlasmaPlus AntiCorr process for reliable and environmentally friendly corrosion protection.
PlasmaPlus AntiCorr: Efficient, eco-friendly sealing
By using Openair-Plasma, the sealing points of the battery housing are first micro-cleaned and then coated with an ultra-thin, highly effective protective layer using the PlasmaPlus process. This silicon-organic coating, called AntiCorr, improves the adhesion of the sealant and reliably prevents infiltration corrosion caused by moisture. The innovative plasma applications developed by Plasmatreat GmbH offer significant advantages over conventional processes such as waxing: they shorten cycle times, reduce logistics costs, enable automated integration into existing production lines - and are significantly more environmentally friendly. The AntiCorr process has already been extensively tested and has passed standard climate and salt spray tests such as the PV1209 or the MeKo-S test.
Successful technology, expanded application
A particular challenge in this project was to meet both the high process speed and the special requirements of the production line. "In close cooperation with our automation partner Linamar, we succeeded. Together, we even exceeded our customer's high expectations," says Lukas Buske, Managing Director of Plasmatreat GmbH. In 2021, the first plasma system will be installed in one of the carmaker's Czech plants. Due to the success of the new automated corrosion protection concept, the customer is already planning to expand the technology to two other plants.
