The Gerg Family – a Family Business

Inspired by his father, Blasius Gerg sen., an academic sculptor, today’s head of the company, Blasius Gerg, decided to complete an apprenticeship as a model builder. After a short time as a journeyman he successfully graduated as a master craftsman. Shortly after he founded his own company in order to realize his quality standards and ideas. more >>

Everything started in 1984 as a one-man business in a garage in a small village called Haslach, Upper Bavaria, Germany. The first order included the making of models for home appliance. They were followed by different design and function models, such as cross-country ski bindings, a film camera and even a milling machine. With the first casting and mould patterns for a German car manufacturer, the headstone for a sustainable relation with the automotive industry was set.

Under the direction of Blasius Gerg and his wife Maria, the company has grown over the last decades, expanded and developed a diverse range of competence centers.

Until today, the company Modell- und Formenbau Blasius Gerg GmbH is still a family-run business. In the meantime the second generation is already involved in the firm.

What once used to be the founder‘s imagination and his creative talent on a small-scale has transformed into the big picture with innovation-friendly atmosphere and positive culture of today’s company group.

Gerg – the History



Management – Responsibility

Responsibility for people instead of a short-term maximum profit orientation: The management cares for long-term commercial health, high quality products and client services, continuous innovation activity, fruitful relations with partners and customers, sustainable investment and an attractive working environment. more >>

Today, besides Maria and Blasius Gerg, Josef Kagermeier is also part of the management. Despite the technical and operative distinction in different departments, the hierarchies are still flat and the ways kept short. Thanks to the campus-style architecture of the production and development buildings, uncomplicated exchange of information and goods within the company takes place easily. The company´s philosophy of a face-to-face management is part of the culture on all levels.



Driven by Sustainability – Hohentann

With us, some things are different many are special – not as a matter of principle but by dedication. An idyllic environment, mutual respect, a view beyond the edge of the plate and ever new challenges result in sustainable motivation. more >>

There are characteristic aspects which cannot be described by economic indicators. Long before it had become necessary to nail the buzzword “sustainability” on your flag for image reasons, it was part of our logical self-conception to work with and not against our natural resources. Heat is produced by wood chips, own solar plants generate electricity, in the canteen we serve local products and our main building material is wood. Therefore, our production site in Hohentann perfectly integrates in the rolling hills of Upper Bavaria´s landscape. While outside cows are grazing, inside we work on high-tech. The idyll of our environment is present in our offices and workshops. Where usually rubber or concrete floors are common use, men and machines stand on wooden parquet. Such features might be explained with corporate identity, sustainability, complacency, corporateness or by work psychological aspects – for us, these features are the result of our attitude and active responsibility towards employees, man and nature.

Innovator Group – Innovative Strength

Where motivated people meet new challenges and have the space and freedom to implement new ideas, innovation will happen almost automatically. You cannot enforce creativity – that is why we cultivate it consciously.

Structural components – complex composites

With our specifically developed composite technology we are able to produce complex structural components which so far could only be built with casting or rapid prototyping technology. The composite components feature perfect surfaces off tool and we lift dimensional accuracy, aesthetics, functionality and load capacity to the highest level.

Complete solutions – individual vehicle construction

A custom-made vehicle is a masterpiece of technical culture. Our profound know-how and in-house production enable us to produce completely independent, individual vehicles, tailor-made to our customers’ demand.

Aluminium precision casting – finest structures, maximal strength

Mankind has been developing the casting technique for more than a thousand years now. In the field of aluminium precision casting, our expertise is the peak of this development. With our unique casting technology we realize sophisticated surfaces, complex outlines and minimal wall thickness. This kind of quality you will find only with us.

Titanium machining – close to the limit

No other material has such an extremely high ratio of strength to weight as titanium has. This feature makes its applications so attractive for motorsports, the aviation and aerospace industry as well as the sports sector. The successful machining, however, requires a great deal of know-how, experience and specific machinery. We are specialised in titanium machining and are able to optimise the use of all benefits this extraordinary material has to offer.
