Decorative and functional surfaces
With around 30 million polyamide and approx. 60 million single and multi-component parts per year, SAXONIA Galvanik is one of the leading international suppliers in the field of chrome-plating on plastic. Four modern large-scale plants enable a capacity of approx. 1,500 m2 of metallized surface per day. Since 2020, more and more product ranges can be coated completely free of chromium(VI) in a process- and series-safe manner.
In 2018, JKL Kunststoff Lackierung GmbH also became part of our group of companies: as a specialist in the painting of large series, we finish up to 10 million parts a year in fully automated robot painting line – and give them a special aesthetic and touch feel. In cooperation with specialized research partners, various processes have been introduced and optimized in recent years that guarantee the safe and sophisticated coating of highly complex parts.
With 50 years of experience, comprehensive process know-how and the use of state-of-the-art equipment, surfaces from SAXONIA Galvanik have all the optical, haptic and functional properties that are important in the fields of (e-)mobility, electronics, the household appliance and sanitary industry and medical technology.
Process approval for completely chrome(VI)-free production line by VW
At the beginning of November, the entire process sequence at SAXONIA Galvanik GmbH was audited by VW as part of the chrome revision. This also included the two chrome(VI)-free process steps pre-treatment and deposition of the metallic final layer on a series production line. We were able to give the auditor insights into our company and answer all questions. The audit was passed. This is the first time that a process approval has been granted for an entire plant. The approval refers to interior parts that we produce in bright or matt chrome for VW Group vehicles. The approval includes all brands of the VW Group, such as Audi, Porsche, Skoda, Seat and Bentley.
First OEMs confirm quality of the completely chromium(VI)-free plating process
For half a year, the new completely chromium(VI)-free plating process for plastics has been put through its paces in a converted series plant in numerous sample campaigns. In the process, both the pre-treatment/conditioning and the final coating were changed. The aim is the sampling and external release of products already in series production, as well as the initial sample release of new articles. With Stellantis (PSA/FCA) and Skoda, the first car manufacturers have now confirmed the performance of the new process. The temperature, climate change and corrosion tests carried out were passed in full. The first automotive series projects in the demanding interior have been approved by Daimler. Among them is a demanding 2K part. Audi projects are currently in the final phase of EMPB approval. Further projects will follow successively.
For assortments from the household, caravan and electrical sectors, the conversion to large-scale series production has already taken place. These steps are important for the upcoming complex conversions of other production lines in the next few years, including the numerous re-sampling processes within the supply chains, which will take several years to complete. The conversion of the next two series plants has already been scheduled.
