Kalmbach - profiled in performance

Innovation, flexibility and extreme quality and standard optimization are the three pole "performance profile" of my company.

Founded in 1964, since 1994 in my hands and from 2001 at the new location in Tübingen Pfrondorf.

Customers with my staff and me to work together with confidence for many years, know that they are in capable and competent hands.

Based on a wealth of experience we offer you the complete width of the innovative production of particle foam - mold making:

From design test tools and prototypes to series production of foam molds for EPS, EPP and EPE production.

Maintain the best possible continuity of the CAD data of the desired part in the design, our CAM systems in the work preparation to CNC machining - center in manufacturing - which is at the core of our concept of good work.

In addition, we work with our ultra-modern machinery in contract manufacturing. Main focus: the sophisticated machining of aluminum.

Today at Kalmbach highly trained and constantly trained staff with years of professional experience. In order to maintain this high standard in the future, we will make of course yourself.

When it comes to new developments, a decent price - go for money or maintaining the tightest deadlines, you can rely on us.

Ask for my staff and me with your tasks and projects. We like profile for you!
