Competences of the Grunewald Group
- Continuous technical and staff development
- Solving of complex requirements
- Integrated manufacturing of the highest quality
The restructuring in 2012 in the course of an expansion and amalgamation of the foundry activities resulted in the fact that we are able to manufacture individual and series products at the highest level of quality.
We are able to manufacture prototypes made of iron cast material or aluminium, as well as small series cast parts of aluminium. Due to the low pressure casting technology we are achieving highest repeatabilities to maintain a high quality standard.
We offer our customers complete machining on our state-of-the-art 5-axis machining centres. We perform the subsequent quality control on conventional 3D measurement tables, using a 3D scanning system or a CNC-controlled measuring machine for series measurements.
At our headquarters location, we are able to machine workpieces of a total length of up to 14 meters. We are measuring the respective raw and finished parts with our comprehensive measuring/gauging equipment. The subsequent assembly as well as the potential customer acceptances are performed directly on-site.Our CAD department, with currently 17 employees at all our sites, is integrated directly in the work in manufacturing.
Due to the production-suitable separation of CAD, model construction, assembly as well as our mechanical machining at, on the one hand, our headquarters and the foundry on the other hand at our expanded site we can optimise the throughput times for our prototypes and series castings.
The same applies to our toolmaking, which also profits from the optimised casting technology.
The cast parts produced with our new sand casting process are being produced so that less finishing work is necessary and they have the advantage of being manufacturable with greater form stability at less effort. We are now able to manufacture complete cast parts at one site, including the adjustments and the quality control. Thereby we are lessening the throughput times at the simultaneous increase in productivity.
All manufacturing steps, beginning with the CAD design, via the toolmaking and modelmaking as well as various rapid prototyping processes to the mechanical finishing are concentrated at the Bocholt site under one roof and ensure shortest production routes. The results are a lowering of the costs and a reduction in throughput times.
