The Diem-Werke

A success story.

When: 1949
Where: Dornbirn
Company founder: Alfred Diem

The period immediately after the Second World War was marked by an acute shortage of raw materials. A talent for improvisation and construction skills were much in demand. These valuable skills allowed company founder Alfred Diem to lay the stable foundations for a company which continues to flourish today.


Diem opens for business in Dornbirn, as a workshop with one employee. Its first product is a mass-produced kitchen knife, manufactured from metal scraps from the armaments industry. In addition, written-off military vehicles form the basis for farming tractors and electricity generators. In this way, the company is able to supply sawmills with transport vehicles and lifting tools.


Alfred Diem already holds numerous international patents. Hundreds of the first mass-produced mixers are also delivered.


The first pressure vessel heads are produced. The customer is Hoval Werke, based in Vaduz, Liechtenstein.


Development of the first drive motor-operated cement mixers.


Space requirements require a relocation to Lochau, to the premises of the former Bayerische Leicht Metall Werk, and previously the Oberhänsli Dieselmotoren Werk. Diem Werke's subsequently further grows into a modern production business.

This allows Diem Werke to grow into a modern manufacturing business.


The son of the founder, Mr. Harry Diem, took over the management.


We take over a storage engineering business. With annual increases in sales revenue of at least. 20%, Diem Werke thus becomes one of the leading producers in this sector.


Premiere of a modern classic: The first high performance pan mixer from the legendary DZ 120V range is produced. Even today, synonymous with reliability and durability.


The Diem-Werke GmbH takes over the warehouse and office areas of the former Resch area in Lochau. The so-called "Werk II" is used as construction machinery and tank warehouse.


A milestone for the mixing of non-flammable masses and steel-reinforced concrete: dynamic agitators for pan mixers. Extremely low wear, even with highly abrasive materials.

Structural expansion of warehouse space in "Werk II".


Establishment of a 7000 m² production hall with administrative building in Hörbranz. A connection to the warehouse "Werk II" by bridge is also provided.
