This week, SHW Casting Technologies in the Königsbronn works celebrated the completion of a particularly large order. The company delivered a paper roller weighing 66 tons to a Swiss customer. The paper roller is more than 10 metres long and has an external diameter of 1.4 metres. It will in future produce 2,000 metres of paper per minute.
Six months ago, the company poured more than 100 tons of molten iron into a mould at a temperature of 1,350 degrees in order to manufacture the roller body. This involved using a special material patented and developed by SHW CT, which is called CDI (Chilled Ductile Iron). The last time so much molten iron was poured into the 13-metre-deep casting pit at the works in Königsbronn was eight years ago. Following the casting process, the roller was 12 metres long and weighed more than 100 tons. The cooling process took two weeks, and then the roller was cleaned, machined and subjected to various tests. The experts at SHW CT used a total of 650 individual parts to build the roller.
Managing director Marcus Katholing said, “The team did a great job. We delivered a top-quality product on time. There is only one company in the world that can manufacture rollers of this size and made of this material – and that is SHW CT.”
Since July 2017, the company has been involved in debtor-in-possession proceedings. The long-established company is being supported by the restructuring experts from PLUTA. Since debtor-in-possession proceedings began, Marcus Katholing has acted as the chief restructuring officer. SHW Casting Technologies was created from the foundry activities of Schwäbische HüttenWerke (“Swabian Smelting Works”). The roots of iron production date back to 1365, when monks in Königsbronn began extracting iron from ore.
