In 1924, Otto Junker founded the company bearing his name at Lammersdorf, some 20 km south of Aachen. The economic foundation of what was originally a craftsman's establishment lay in the water-cooled billet mould for the nonferrous semi-finished products industry that had been invented by the founder's father, Andreas Junker.

Over the decades that followed, OTTO JUNKER GmbH evolved into a successful medium-sized industrial enterprise with a comprehensive product range.

Since the death in 1982 of Dr.-Ing. E.h. Otto Junker, its sole proprietor, the company has been owned by the Otto Junker Foundation, an institution set up in 1970 with the primary aim of supporting young engineers.

Experience, sustainability, future orientation

„Our primary objective is the promotion of technological progress in order to increase the customer benefit in the foundry and semifinished products industry, but not only in this industry”, Erik Miček, CEO of OTTO JUNKER GmbH, stresses. In 2024, OTTO JUNKER can look back at a century of experience, technical progress and highest quality standards and will continue to follow the path towards sustainability and transformation it has started. Especially after the clear positioning towards electrification in the planning of new equipment and modernizations and the approval of visitors at the GIFA/Thermprocess 2023, the company is looking forward to the future with confidence.

Corporate philosophy

Determine all problems impartially, find a solution through joint academic and industrial enterprise, and deliver the result to the customer in the form of quality products.

This motto of our company's founder, Dr.-Ing. h.c. Otto Junker, applies more than ever today.

However, achieving this goal  necessarily involves a number of success factors.

First and foremost among these is our workforce - about 450 skilled, experienced and  highly motivated  employees, plus about 25 technical and commercial apprentices each year, who excel at their diverse duties and share a commitment to the guiding principle established by the company's founder.

At OTTO JUNKER, product and equipment requirements are identified side by side with the customer, always with a view to attaining the desired final product quality. The vast stocks of experience accumulated by the plant operator and equipment manufacturer are thus combined to achieve a tailor-made solution. We also cooperate closely with the customer in reviewing existing installations for performance, energy efficiency and other improvement potentials.

Furthermore, OTTO JUNKER has efficient in-house R & D capabilities which allow us to address all aspects of industrial furnace engineering. Our proximity to RWTH, the Technical University of Aachen, gives us access to extensive expertise and enables us to engage in joint research projects. The insights thus gained will then find their way into innovative solutions implemented in specific industrial furnace projects.

The quality of the end product is our measure of success.



OTTO JUNKER foundation

Otto Junker studied at RWTH Aachen University and later always gave students, undergraduates and doctoral candidates at the Foundry Institute and the Institute of Electrical Engineering the opportunity to gain practical experience at the company. In 1943, Otto Junker was made an honorary citizen of RWTH Aachen. In 1962, he was awarded an honorary doctorate for his great commitment to the university.

In 1970, the Otto Junker Foundation was established by Dr.-Ing. h.c. Otto Junker as a foundation to receive his estate.

He pursued two main objectives in setting up this foundation:

On the one hand, he wanted to ensure the continuity and continued existence of his company; at the same time, however, he also wanted to use the income from his company to sustainably promote science and research, the growing importance of which Otto Junker had recognised early on.
