HOW WE HAVE FORGED OUR VALUES
DANGO & DIENENTHAL was founded in 1865 by August Dango and Louis Dienenthal as a non-ferrous metals foundry. During the first four decades of the twentieth century, the company’s core business gradually shifted towards the manufacturing of specialist machinery. Today, the family-owned company is in its fifth generation, managed by Rainer Dango und Arno Dienenthal.
In addition to the headquarters at its place of foundation in Siegen, Germany, DANGO & DIENENTHAL has subsidiaries with production facilities and service offices in South Africa, North America, India, Japan, Russia, China, Mozambique and Sweden.

In 2012, DANGO & DIENENTHAL Hollerbach GmbH was founded, expanding the company’s range of automated handling systems for heat treatment processes.
Since 2014, DANGO & DIENENTHAL Umformtechnik GmbH has been manufacturing and supplying roller bending machines for large, heavy-gauge plates, and induction bending machines especially for large-diameter thick- and thin-walled pipes. A strategic partnership with a measuring technology specialist, entered into in 2019, enables Dango & Dienenthal to supply – as a novelty in pipe making – gauges for the measurement of the inside wall contours of pipes. Revamping service for hydroforming machines is also part of the company’s service portfolio.
Since the foundation of our company, we have supplied more than 1,000 machines and systems. Family-owned and managed in the fifth generation by Rainer Dango und Arno Dienenthal, the company today has 730 employees worldwide.
