The Tarnów Foundry specializes in manufacturing single casts and small to average series (preferred batches 100-200 pieces/month). Manual forming takes place in round or rectangular flasks with maximal size of ∅ 2200 for the round flasks and 3600×1900 or 6700×900 for the rectangular flasks. The maximum weight of a casting is 4 tons.
The forms, as well as most of the cores, are made with use of continuous whirl mixers from furan mass based on reclaimed quartz sand. The Form Making Department has two Wohr whirl mixers with efficiency of 15t/h and 12t/h. The entire mould mass (including the core) undergoes process of mechanical recycling. The fully automated station of mass processing allows us to recover about 85-90% of the quartz sand.
