We think the process through to the end and offer surface treatment, heat treatment and mechanical processing from a single source.
Post-processing of grey and ductile iron castings is crucial to ensure the highest quality and performance. Sandblasting, annealing and priming are combined with mechanical processing methods such as milling and turning to achieve an optimal surface and structure. These processes improve not only the aesthetic characteristics but also the functional integrity of the parts. Comprehensive quality assurance is essential to ensure that the machined castings meet the strict standards and specified requirements before they are put into use.
Surface treatment
Deburring, sandblasting and painting
In the fettling shop, the raw castings go through the sandblasting system. Large workpieces are processed in the overhead conveyor blasting system, small cast products in the troughed conveyor blasting system. They are deburred, risers and gates are removed and can then be primed by us. Our employees' many years of experience in deburring ensure visually appealing castings.
Heat treatment
Reducing stresses in the workpiece
The annealing furnace is used to reduce stresses in the structure. During thermal post-treatment, the casting is heated to a certain temperature and then slowly cooled down. This allows the atoms and molecules in the metal to rearrange themselves and achieve more stable structures.
Mechanical processing
Turning, milling or drilling - machining from a single source
As a leading manufacturer of sawing machines, we have many years of experience in the production of ready-to-install cast components. We offer a wide range of machining services on CNC-controlled automatic lathes and milling machines to meet your requirements.
Quality assurance
Quality management according to DIN EN ISO 9001
The manufacture of high-quality products requires continuous monitoring of the production process - from the raw materials to the finished casting. We ensure consistent quality by testing mechanical parameters and chemical analyses. Our commitment to quality is reflected in ongoing investment in modern equipment, the continuous optimisation of production processes and quality management and the training of our employees in accordance with the latest standards.
Painting
High-quality painting for long-lasting protection
Professional painting of your cast part protects it from external influences and makes it more resistant. Painting cast parts in our own paint booth can be carried out under ideal conditions. You have the choice between simply priming the cast product or painting it in the colour of your choice, ready for installation.
