2P machines

Colosio's production of cold chamber diecasting machines 2P -2 platens - for diecasting of aluminium and magnesium alloys - ranges from 1000 up to 3.200 tons clamping force.

Fully digital, Colosio's machines are equipped with data storage of dies (Coltrol System). The monitoring and storage of process data allows accurate repetition of all the injection parameters, pressure, speed and stroke for any possible die, always keeping under control the injection curves thanks to the graphical display of every single shot (Fullcoltrol).

Descendant of the well known V2 System, the new Futura double circuit injection system with floating piston accumulators works at the highest speeds, also enabling the operator to choose between a 1st phase with constant speed (under pump) and a 1st phase with progressive speed (under accumulator). Furthermore, the intensification phase is carried out with a separate circuit, fed by a separate, pre-chargeable accumulator, which always guarantees the necessary power to this crucial phase.

On demand the machines can be equipped with a REAL TIME injection system of speed and pressure.

The closing is done by a hydraulic clamping device. This system provides two cylinders with reverse piston rod for movement of the platen during the phases of closing and opening; 4 big section cylinders  are used to apply the closing force by means of special jaws grip on the tie-bars.
These are made ​​of high-strength steel, hardened, hard chrome-plated, grounded, with rolled threads and bronze guide bushes, correctly sized, to adequately support the platen in its translation motion. The whole closure is equipped with protective casing to reduce the sensitivity of dirt on the mechanics. The upper tie-bars are easily removable for assembly and disassembly of molds particularly bulky through the action of special telescopic cylinders mounted above the mobile plate.

The new series Colosio 2P pays special attention to the size of the working greatly reducing the needed space for the same tonnage with a traditional machine knee. Thanks to the new system of closing the machine is able to control at each cycle the closing force automatically compensating possible problems of parallelism of the molds used.

Upon request the machines up to 2P 1600 can be available in version GREEN LINE.
