HISTORY

HOW WE HAVE FORGED OUR VALUES

1865

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 special machinery. Today, the family-owned company is in its fifth generation, managed by Rainer Dango und Arno Dienenthal.

2014

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.

At the end of 2015, HENCON BV, based in the Netherlands, became part of the group, completing DANGO & DIENENTHAL’s portfolio with machines and equipment for the aluminium, mining and forestry industries. In addition to the supply of machinery, HENCON provides a wide range of on-site maintenance and service activities.
