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.
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.
