Ordered after extensive bench-mark tests had confirmed the superior quality of the molds produced on HANSBERG molding machines, this truly state-of-the art facility produces nodular iron safety castings, including suspension arms for various major automotive companies.
Rated at 200+ molds/h with internal flask dimensions of 790 x 1,050 x 230/230 mm and 60 min cooling time, the HANSBERG green sand molding line for the GEORG FISCHER foundry in Singen stands out as one of the most productive facilities in the industry.
The facility has an extremely compact, linear layout, allowing for reduced shop-floor occupation and foundation requirements.
Both cope and drag molds are produced by a single pre-fill/shoot/squeeze, vertical-loop molding machine. In this type of machine, the cope and drag pattern-plate bolsters travel in sequence first through the pre-fill station, where they mate with the corresponding flask and are partially filled with facing sand, then through the shoot/squeeze/strip station, where the actual mold is made and stripped from the pattern.GEORG FISCHER AUTOMOBILGUSS, Germany
