1930 – 1960

In the 1930s, production is successively expanded to include plant construction – especially for the cement industry. After the death of the childless founder, Franz Bartscher (nephew of the founder) joins the company as managing owner. There is a shift of emphasis from mechanical and plant engineering to pure foundry.

Introduction of the material ADI.

1986

Schonlau will be a pilot project of the program ” Improvement of Living Space in Mixed Situations“ of the state government of NRW. One of the most extensive environmental protection programmes in the region is initiated.

1990

Completion of the pilot project. The living environment has been significantly improved, the workplaces have been humanised, the moulding facilities, etc. have been renewed and brought up to the latest state of the art: Investment volume: DM 12 million. As can be seen today, the existence of the company is secured in the long term.

The Great Fire

Just in times of economic upswing, a major fire destroys more than two thirds of the buildings, and adjacent production halls are also affected. The heart of the foundry, the melting shop, the sand preparation plant and parts of the automatic moulding plant were completely destroyed. The total damage amounts to more than 10 million euros.

The chance in the crisis:

The owner family decides to rebuild and thus to save 120 jobs. Production processes and environmental protection measures are significantly optimized. After a record-breaking seven weeks, the first furnace is up and running again, – production is initially only temporarily in the open air. After nine weeks, the new sand processing plant (Eirich) is ready for operation. Above-average commitment and an exceptionally productive cooperation between management and team lead to this top performance. We are rightly proud of it! Even relevant trade magazines reported on our successful reconstruction, some even with a cover story.

2007

Construction of the new 1,100 sqm dispatch hall.

Commissioning of the new annealing furnace for stress-relieved and ferritic annealing.
