We l come to the qu a l i t y o f HOFMANN Wär metechnik OFMANN Wärmetechnik looks back on a long tradition in the range of plant designing and construction. The designing and construction of furnaces and facilities for heat treatment in various branches reaches back to the year 1946. The company was established by Mr. Herbert Hofmann. In 1974 Mr. Hermann Gründl took over the company and enlarged the location in Linz. Since 1999 the company has been led by Mr. Niederländer and his wife. In the last years Hofmann has been specialising on heat treatment for aluminium and steel parts. The new company...

Description of the facility 11 took a few months of designing and constructing to meet the needs of the customer. A main challenge was the handling system of the facility. Due to the high level of automation it was necessary to include the new solution heat treatment facility in the complete process of the customer. This results in a very flexible but easy to manage system which ensures the operator to handle parts up to 2500 mm ergonomically. The charging is carried out into charging frames which are then put into the charging basket. From charging and discharging the baskets all process steps...
