Engineering –
Expertise from Thuringia
Our roots lie in traditional toolmaking and special machine construction – but our thinking has long been focused on Industry 4.0. With a well-coordinated team, state-of-the-art machinery and in-depth expertise, we support our customers along the entire value chain:
We think ahead
Every project begins with a clear goal – and a strong idea. We work with you to develop tailor-made concepts that are technologically sophisticated and economically viable.
We manufacture with µ precision
State-of-the-art CNC technology, maximum vertical integration and a team that lives and breathes precision: this is how we create components that set standards in every respect – for today, tomorrow and the long-term future!
We assemble systematically
Whether it’s a one-off or a series solution, we bring components together intelligently. Manually, semi-automatically or fully automatically. Always tailored to your processes and requirements.
We ensure quality
Certified according to ISO 9001 and equipped with comprehensive testing technology, we ensure that everything fits – down to the last detail. This creates trust and saves costs in the long term.

Family business with vision
Since its foundation in 1992, our company has grown organically – in terms of expertise, size and responsibility. Despite technological excellence, our corporate culture has remained informal to this day. Mutual trust, personal interaction and short decision-making processes characterise our daily cooperation – both internally and externally.
Our management team combines technical expertise with entrepreneurial thinking. The company is now in its second generation of family management – with a clear focus on future security, quality and humanity.
