toolmaking
Our tools, which are up to 5 meters long, pass the endurance test before delivery: the components are tryout on a 2,500 t Schuler press. Using the latest grinding technology, we achieve the highest dimensional and positional tolerances and ensure surface quality that sets standards. Thanks to a processing accuracy of ±0.01 mm, we guarantee solutions that combine stability, durability and precision — for components that impress from the very first part. Our maintenance and repair service is recognized across the industry, and replacement tools are available in just 48-72 hours in an emergency.
An overview of our tool portfolio
Blanking dies
Our tryout press adjusts cutting, forming and transfer tools under real conditions. For minimal rework and maximum process reliability from the first stroke.
Progressive Tools
From the circuit board to the finished part in one run: Our sequential tools automatically connect up to 20 work steps. This means: less handling, more speed and precision for your high-volume production.
Prototype Tools
riemann prototype tools combine craftsmanship with cutting-edge technology. The basis for your series parts is created quickly and in line with the application — perfect for automotive, agricultural technology and complex designs.
