Company founder Hans Georg Hillreiner was always convinced of the idea of self-employment.

In 1987 he successfully passed his master's examination. With this qualification and the subsequent foundation
In the original mechanical workshop, he begins production on his first machine.

A small series for MAN and cruisers as well as devices for BMW are manufactured on it.

In 1991, the move into the new company building follows, as another machine is needed due to the great demand.
Due to the high quality of the parts produced and the associated increase in orders, a support worker was hired in 1995 and the existing production building was enlarged.

In 1998 a new production building is built. This is equipped with new machines and more employees are hired.

In 2000, customer demands and orders are increasing rapidly, requiring the production of larger quantities of a wide variety of parts.As a result, an administration and office building is built in 2001 and HGH moves into it.

In 2017, HGH was renamed a GmbH and handed over to the daughter Barbara Hillreiner.

Our management system was already certified according to ISO 9001:2008 in 2011.
As part of the re-certification, we were audited and certified according to the new ISO 9001:2015 in autumn 2019.
Due to constant testing of the effectiveness of quality-related activities, the organization and methods of quality management in our company are constantly being adapted to the latest findings and requirements.
