Our history - innovation from tradition
For over 50 years, formoplast has stood for quality, innovation and reliability in the manufacture of tanks for the storage of water-polluting media. What once began as a small forge is now a leading company in plastic tank construction.The roots of our family business
In Nordholz (Bavaria), Dr. Hans Keller establishes the company Sebastian Keller Nachfolger – a business that evolves from his father's blacksmithing trade. The initial focus is on the production of steel parts.
An innovative step
With the first liquid fertilizer container made of fiberglass-reinforced plastic (GRP), formoplast lays the foundation for its specialization.
The birth of formoplast
Foundation of formoplast-chemie Dr. Hans Keller GmbH. The focus shifts to the production of storage containers made of GRP - a technology with a future.
