Precision and power on 14,000 square metres

The technical know-how of our employees is perfectly complemented by a highly modern train of machines.

We are firmly convinced that we can only persist as an innovation and quality leader if we consistently focus on two points. Delivering the best quality requires highly motivated employees with excellent technical skills and extensive creative freedom as well as a highly innovative train of machines.

We fabricate our products with the following machine types in various dimensions, among others:

• Travelling column milling machines
• Gantry milling machines
• Horizontal centres
• Lathes
• Processing centres

In steel construction we work with gantry robots and robot cells among others. Here and also in manual welding, we employ welding specialists with excellent training who hold the proof of suitability certificate according to DIN 18800.

As experts in the fields of mechanical engineering and automation technology, we also pursue the continuous further development of existing systems in our manufacturing sector. We have already realised a variety of fixtures, delivery systems and machine adaptations for the continuous optimisation of processes and quality. If you stop getting better, you stop being good.

In addition to a corresponding layout, the best base materials and excellence in production, Demmeler guarantees the best quality in the market through quality assurance equipped among other things with 3D coordinate measuring machines and optical measuring instruments. Naturally inspections and measurements are performed in air-conditioned measuring rooms in order to ensure that the corresponding tolerances are met.
