10 years of dedication, precision and team spirit
A few days ago, we had the pleasure of celebrating a very special anniversary:
Wolfgang Hagner has been part of the Arnold Group since 1 May 2016 – and has thus been an indispensable pillar of our machining team for 10 years now.
As a machining technician specialising in turning, Wolfgang impresses day in, day out with his exceptional precision, extensive expertise and impressive commitment to quality. What in production often looks at first glance to be ‘merely’ technical work is, in reality, true craftsmanship – and it is precisely this that Wolfgang has been living out with total passion for a decade.
We particularly value not only his technical expertise, but also his reliability, his helpfulness and his long-standing loyalty. People like him leave a lasting mark on a company: through experience, loyalty and a willingness to always take on responsibility.
10 years of service means:
10 years of dedication.
10 years of trust.
10 years of shared growth.
And countless hours spent contributing to the success of our company with the utmost care and commitment. We would like to say a heartfelt thank you today for this long-standing loyalty and daily dedication. We are proud to have Wolfgang on our team and look forward to many more years together.
Congratulations on your 10th anniversary, Wolfgang, and thank you very much for everything you do for the Arnold Group!

Five young people gain insights during Girls’ and Boys’ Day at Arnold
Yesterday, we hosted Girls’ and Boys’ Day at our premises. Five young people had the opportunity to gain an exciting insight into our working environment.
From the welding shop and the training workshop to the assembly, design and electrical departments – through a series of short stops, they were able to get to know different areas and form their own first impressions. We hope we were able to provide a clear and informative overview of our production processes and perhaps even sparked an interest in one or two of the professions.
Thank you very much for coming – and all the best for your future! You did a really great job
