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