Company

1888

Company founded by ERNST HINRICHS in Osterode. The first dental impression and model plasters are developed with dentist Dr. Kühns. The positive response to these world-first dental plasters enables the purchase of the company premises in Osterode on the Gipsmühlenweg.
Dr Kühns’ impression plaster is especially successful, and also the newly developed model plasters
with reduced expansion and exact setting time.

1920

Sons Ernst and Richard Hinrichs join the company. The first „Hinrizit“ hard stones and gypsum-bound investments are developed. With the installation of modern electric sifters and screening machines, the quality of the dental preparations is being constantly improved and their further development tailored to dentistry and dental engineering. In 1936, the first soldering compound „L 36“ is developed.
