Z2 PR / Extrusion Press

The principal function of Extrusion Press is to make flow the aluminium through the die at a controlled speed and temperature. This is achieved by means of hydraulic cylinders and hydraulic circuits controlled by a PLC system.

Main Characteristics:

• The main tandem cylinder allows reducing the distance between columns allowing designing the more compact press on the market that causes a minimum deflection of the front plate and improves the quality of the extrusion process.
• The Front Loading design reduces the length of the whole press (cylinder stroke, columns length) improving the dead cycle time and the oil flow.
• Symmetrical upsetting of the Billet minimizes trapped air and radial stress, and allows a uniform flow of aluminium during extrusion.
• The combination of the two previous features gives to the Tecalex Press a reduced dead cycle time.
• The container holder is made of welded steel (St52.3) and it is moved by two container cylinders.
• Container are made of 3 parts, the mantel, the liner holder and the liner, this allows having an optimal fatigue resistance improving the maintenance replacing period.
• Tecalex presses also integrate a rotatory die changing system that allows changing the die in a very fast operating time.
• The hydraulic circuit blocks and pumps are located on two steel frames just behind the press at floor level to make maintenance operations easier.
