The roots of IMAS can be traced a long way back, namely to 1945 in which year the business was founded by the manufacturer, Henry Poulsen, in central Copenhagen. Learn more about the history of IMAS from the timeline below.

The business, H. Poulsen, is founded by the manufacturer, Henry Poulsen.

H. Poulsen moves to the suburb of Brønshøj.

Up until 1952, the focus area of H. Poulsen is the production of aluminium buttons.
This was also the year (1952) marking the employment of 10-year old Mogens Poulsen –second generation and son, Henry Poulsen – in the capacity as errand boy.

During the years 1952-1958, H. Poulsen develops a good and steady collaborative relationship with the renowned Danish engineering consultants, FL Smidt og Co. – at the time the predominant customer of the enterprise. Unfortunately, this collaboration was brought up short when, in 1958, FL Smidt og Co. in Copenhagen was destroyed by fire.

15 years old, Mogen Poulsen leaves school to be apprenticed as a machine worker with H. Poulsen under the supervision of his father, Henry Poulsen.

H. Poulsen machines all Cuckoo-lark parts for copies of 19th century Bornholm grandfather-clocks.

19-year old Mogens Poulsen has served his apprenticeship, and – after compulsory military service – he is again employed with H. Poulsen, where he remains for the next few years.

The manufacturer, Brdr. Michaelsen in Hedensted offers to train Mogens Poulsen as a mechanical engineer. Thus, on 1 August 1964, he leaves H. Poulsen to take on employment in Hedensted.

Henry Poulsen is taken seriously ill. Mogens Poulsen leaves his job at Brdr. Michaelsen i Hedensted in order to return and take over the reins of H. Poulsen.

In August of 1967, Mogens Poulsen initiates his own production of snap couplings for pneumatic equipment. This, then, unique product constitutes the foundation for a financially sound growth of the business that, in the same year, is renamed to ”H. Poulsen & Søn” (H. Poulsen & son).

After many years’ illness, Henry Poulsen dies. The second generation, Mogens Poulsen, takes over the ownership of H. Poulsen & Søn.

The premises in Brønshøj prove to be too small. Hence, H. Poulsen & Søn invests in larger buildings on Baldersbækvej 46 in Ishøj (another Copenhagen suburb).
Also, it has become time to plan ahead. Since personal names as names of businesses do not reveal much about the activities of such businesses, the name of the firm is changed from ”H. Poulsen & Søn” into ”Ishøj Mekaniske A/S” (Ishøj Mechanical).

As, once again, the company lacks space, the 1980s see the yet an expansion, i.e. the purchase and incorporating of Baldersbækvej 45. This is not least owing to Mogens Poulsen’s development and commencement of the manufacturing of cylinders for PFAFF industrial sewing machines. A project that soon comes to constitute 93 percent of the turnover.

Another Mogens Poulsen development project proves successful – in collaboration with Dan-inject, the anesthetising gun becomes a reality. To this very day, it remains a major Dan-inject success.

The third generation, Allan Rasmussen, son of Mogens Poulsen, takes up apprenticeship as a machine worker at Ishøj Mekaniske.

Allan Rasmussen tries his strengths against other firms within the trade.

Allan Rasmussen follows the footsteps of his father and grandfather. He gets his basic professional training with Ishøj Mekaniske and takes over the daily management after having measured his strengths against similar firms within the trade for a number of years.

In June 2005, Mogens Poulsen retires, and Allan Rasmussen takes up the post as managing director of Ishøj Mekaniske.

On 1 January 2006, Allan Rasmussen takes over Ishøj Mekaniske, and the machining workshop is set up for a new chapter to take its beginning.

As the financial crisis hits Danish society, Ishøj Mekaniske is well in hand, commercially. However, as the crisis entails a recession within the trade at large, Ishøj Mekaniske is obliged to resign itself to a period of stagnating developments.

However, from 2012 and onwards, developments begin to turn around, and – once again – Ishøj Mekaniske is commercially successful. Thus, the purchase of 6 machines eliminates superfluous floor space.

In the spring of 2016, Allan Rasmussen is approached by Sulzer/Micpak Denmark A/S concerning the feasibility of the company’s purchase of approximately 3000 square metres of suitable buildings in Greve being vacated as a customer is taking their activities abroad (M. Krøger (subsequently Sulzer) – manufacturer of joint-filler guns). Soon, the buildings on Baldersbækvej are sold.

In the autumn of 2017, Ishøj Mekaniske moves into the new buildings, located on Geminivej 4-6 in Greve – with only seven days of production standstill.


Ishøj Mekaniske leases a little over 1000 square metres to close collaborative partners.


Organizational changes has been made allowing CEO Allan Rasmussen to focus on his responsibilities in the Sales Department in the future.

In the hope of inspiring more young people to take a vocational education Ishøj Mekaniske has entered into a collaboration with the Youth Center in Greve Municipality and seven local primary and lower secondary schools. On 17th of June Ishøj Mekaniske Roskilde won the price for best Internship in Køge Bugt 2020. We won the price for our commitment and efforts to get more young people in the local area to choose a vocational education and apply for a job in the industry.

In addition, the factory now has a food registration so that we can now produce and deliver components for customers in the Food Industry.

This year Ishøj Mekaniske celebrates its 75th anniversary.

Ishøj Mekaniske changes name to IMAS A/S.
