The same advanced technology that goes into the design and manufacture of the standard range of Brake presses goes into the range of custom or purpose designed brake presses. It is not uncommon for a particular job to be made 100% more efficient through the use of the correct machinery for the manufacturing process. For instance, instead of making two panels at 6 metres and butt welding, a single piece at 12 metres eliminates an entire process.

Durma can supply custom machines from a simple tandem prepared 6 metre 300 ton with custom material positioning mechanisms right through to the more extreme capacities such as a pair of 8 metre by 2000 ton brake presses with tapering front gauges and 1000 mm high tooling for making light poles. Larger machines are also available up to lengths and capacity with 16 metres and 4000 ton.   The machines are available from Acra Machinery .

The engineering and manufacturing techniques that go into the extreme duty brake presses needs to be of a high level and Durma certainly provides this. All structural steel is certified. Every piece of steel is sand blasted prior to flame cutting to improve cutting quality and surface finish. Submerged Arc and Robot welding is employed to provide a consistent welding process and robust frames. After welding, the components are stress-relieved to minimise stresses in the frame before machining.

The new Okuma bed mills are utilised for the machining of the bodies, with a capacity up to 20 metres in length. Once the fabricated frame is fixed to the bed of the mill, the entire machining process is completed in a single setup to eliminate any inaccuracies between cuts; resulting in precise surfaces and mounting locations.

The large machines are assembled in a separate area to the regular sized machines to allow Durma to perform testing of the machines according to the application required. For instance, a machine specified for bending Light poles requires a vast amount of space for testing. Also, these machines need to be disassembled prior to transport as often they weigh 100s of tonnes.

So whether it is a standard 3 metre, 120 ton brake press, a 6 metre, 600 ton brake press or a monster pair of 8 metre, 2000 ton brake press, Durma and Acra continue to supply your solutions Today, Tomorrow, Forever.
