Your own Pattern shop is important for us. In-house production or external processing with the materials wood, plastic, composite, metal, polystyrene/ Exporit as one-off designs, modifications and repairs to be able to react competently, flexibly and quickly to changes and customer requirements. Your models are safely stored in our new model hall. In the meantime our inventory of models has increased to some 10,000 units.

In particular in the grinding shop, effective and efficient workflows are important for strict adherence to delivery dates. Our planning team always has your deadline in mind. We communicate with each other openly and quickly. For our staff members we have implemented the latest findings of how to humanize the working world. Optimally designed workstations ensure that the fettler is not exposed to an ergonomically unhealthy posture or excessive strain. Good working conditions are fundamental for motivated staff members. This is supported by our health and safety policy:

 

Along with the melting process the coordinated heat treatment is the basis for highest steel quality of our materials. With our heat treatment possibilities we also offer versatile product characteristics and a permanent continuity of quality.

During the last years we have been consistently pursuing our strategy to specifically increase the benefit and the satisfaction of our customers. One priority has been and still is to further develop our possibilities of mechanical pre-machining and/or finishing.

Everything from one source is for you

• less coordination effort and therefore
• time saving and
• low procurement costs, as well as
• shorter delivery periods due to loss of transportation times between different production sites, but also
• better adherence to delivery dates.

The high quality demands of our customers require extensive quality assurance. We comply with the demands of our customers for high and constant quality of the castings by a very carefully developed working program/process management and strict process controls and component inspections. Monitoring starts with checking the input materials and ends with the output control of the castings. Highly qualified staff members and latest test methods and equipment provide for the required or desired safety.

We regularly check the casting:

Chemical analysis
Material test
Dimensional inspection
Visual test (VT)
Magnetic flaw detection (MT)
Ultrasonic test (UT)
Dye penetrant inspection (PT)
Radiographic test (RT) (external)

Tested quality is assured quality!
