HILGENBERG GMBH – THE COMPANY

Hilgenberg GmbH was founded about 1913 in Stützerbach in the Thuringian Forest – a region well known for its long tradition in glass manufacture. At that time, it was probably unimaginable that almost 100 years later the company would be developing and producing glass products with extremely tight manufacturing tolerances in the micrometer range.

Today, three generations later, the company is still family-owned, and is an innovative and valuable development partner, supplier, and service provider for more than 3000 customers worldwide – from research institutes and universities to large corporations in the chemical, medical, pharmaceutical, automotive, and aerospace industries.

And we have visions: With the purchase and integration of Löwinger GmbH, a German glass producer and machine manufacturer with a long tradition, we have expanded our competences. With this purchase, we have strengthened our technical abilities, increased our production capacities, and accepted responsibility for our company‘s future growth.

Modern production methods, efficient administration, and services close to the customer: From our central locations in Germany, we supply products and services to customers all over the world. This means that every working step is carried out exclusively by our own highly qualified employees – from development through production up to final inspection. Thanks to this “glass clear production”, we are able to guarantee the consistent high quality of our products.
