When Hans Hermann founded the company almost 75 years ago, it consisted of a single workshop. This turned into a factory, and the production of simple standard parts was transformed to ever more sophisticated screws and cold-formed parts.
The second generation took over in 1989 with Erwin Hermann. He shaped the destinies of the company with courage and vision for decades and also in difficult times. Increasing complexity, wider fields of application, customers all over the world – under his leadership HEMA developed into what the company is today: One of the market leaders for high-quality fastening elements and cold-extrusion parts. A healthy, strong medium-sized company. And a major employer in the area. Since 2021, HEMA Umformtechnik has been part of the Keller & Kalmbach group but remains true to its tradition as a deeply-rooted family company. And to its self-conception as a leading company for cold massive forming:
HEMA – the Best that Can Happen to Steel.
