Dong Il 3-die rolling machines from 8 to 50 tons, and the automatic types.
The three sizes step up in rolling force, work diameter and spindle power. The 8-ton machine handles outside diameters from 10 to 50 mm with a 3.7 kW spindle motor. The 15-ton machine covers 14 to 80 mm with a 5.5 kW motor. The 50-ton machine covers 25 to 100 mm with a 15 kW motor. The 8- and 15-ton machines are both listed with a 40 mm maximum length, so they suit short parts. The 50-ton machine is the choice for long hollow parts.
Machine weight rises from 1,800 kg on the 8-ton to 6,500 kg on the 50-ton, which matters for floor loading and installation planning.
The 8- and 15-ton machines suit short hollow and elbow-type products. They use an oil-pressure system, not a cam system. The 50-ton machine is built for long hollow products, including threaded parts for industry and construction.
Dong Il also builds 3-die automatic machines in vertical, pushing and horizontal types. Cinco supplies dies and tooling for these machines. Machines are built to order, and lead time depends on the machine and configuration.
