History
1963
Founded by Felix Grunewald in Bocholt:
Manufacturing of models for the casting industry in the basement of the residential home of the Grunewald family. At the end of 1963, Grunewald is employing three employees. For the visit of the President John F. Kennedy, the model of Berlin's Freedom Bell was cast as a miniature. The bell was manufactured by the bell foundry Petit & Gebr. Edelbrock in Gescher and presented to John F. Kennedy on the occasion of his visit to Berlin. The first milling machine was purchased already in 1963.1964
Move to a larger hall in Bocholt. Production of the first aluminium castings.1965
Hiring of the first trainee.1969
The son of Felix Grunewald, Christian Grunewald, joined the company after completing his mechanical engineering studies. At this point in time, there are 30 employees working.1970
Due to the lack of space, a large piece of property with a building built on it was purchased at the current headquarters in Bocholt.1973
Opening the area of the automotive industry, which was new to Grunewald, required the addition of highly qualified personnel. In addition, a Bohner & Köhle profile milling machine was purchased.1975
Unexpectedly the owner, Felix Grunewald, died in April of 1975. His wife, Elisabeth, and son Christian take over the reins of the Grunewald company.1982
The purchase of a Fluri milling machine with the accompanying measuring machine represented a very large investment. Travels of 2,000 x 1,000 x 1,000 mm and the options of shrinkage and mirror-image milling offer new possibilities to be able to offer and manufacture larger tools.1986
In the spring, introduction of the Euklid CAD/CAM system for three-dimensional designing and 5-axis milling programming.1987
Purchase of a 5-axis milling machine. Contacted the airline industry regarding the new technologies.1992
Founding of Grunewald Tooling in Irxleben with 30 employees who produce die casting and injection moulding tools.1993
Founding of Grunewald + Partner; Rapid Prototyping in Bochum. Manufacturing of "quick prototype parts" as per the stereolithography method and vacuum cast parts. In the subsequent years, expansion of the rapid prototyping technologies to cover different materials.1993
Start of a close cooperation with the engineering office RWP in Roetgen (near Aachen, Germany). Construction of a new "process chain", meaning the development of a product is being accompanied from the start by simulations. During the design phase, the parts are being tested for, for example, ductility, warpage or other potential sources for defects without having to manufacture them physically first.1996
Development of a manufacturing process for cast aluminium prototype castings according to the plaster precision casting method. Patenting of this method.1997
Registration of the process to be patented.1997
Filled an unusual order for the Philip Holzmann company in Düsseldorf. For Building B of the "Zollhof" of the US architect Frank O. Gehry, approximately 600 lost moulds are manufactured. Concrete parts are produced in these forms and later assembled at the construction site.2002
Completion of a factory building at the headquarters with machines having travels of up to 14 m.2004
Founding of Grunewald Werkzeuge&Formen GmbH & Co. KG after taking over a competitor.2004
Founding of Grunewald Guss GmbH & Co..2007
Founding of Grunewald Stade GmbH & Co. KG for subcontract manufacturing of carbon fibre components for the airline industry.2011
Casting of the first iron part.2011
Founding of Grunewald BSB Engineering GmbH & Co. KG in Kirchlengern.2013
Commissioning of a new aluminium and iron / steel foundry for prototypes and small series in Bocholt.2016
Grunewald Stade GmbH & Co. KG is sold to TAI, Inc.2017
Certification of the whole production according to DIN ISO 14001 and DIN ISO 500012017
Grunewald BSG Engineering GmbH & Co. KG moves from Kirchlengern to Bocholt
