Cold chamber


Cold chamber die casting machines from 1000 up to 4400 tons for aluminum and magnesium die casting.

Definitive expression of the utmost innovation and technological research

Each PFO Series die casting machine is designed and built to be fully digital and is completed by a memory to save dies parameters (Control System). The control of the data, their recording and saving allow to repeat the optimal pressure, speed and stroke parameters for each single die, displaying the injection curves for each casting (Fullcoltrol).

The double-circuit injection unit with floating piston accumulators operates at the highest speeds and is suitable for all die casting needs for magnesium, aluminum and brass. The injection allows to choose between a first phase at constant speed “under pump” or progressive “under accumulator”. The control of the multiplier takes place through an independent circuit – powered by its own pre-chargeable accumulator – which guarantees to carry out this phase with the force necessary for each injection profile.


Thanks to more than fifty years of experience in the sector, Colosio specializes in the production of die casting machines for light alloys. The Colosio range of cold chamber machines – specific for the die casting of aluminum and magnesium – ranges from 1000 up to 4400 tons of clamping force.

The Green Line system

In addition to the high technical and production performance at Colosio, we aim to reduce the operating costs and environmental impact of our die-casting machinery as much as possible. This is why we have designed and implemented the system to ensure maximum energy savings.

The aluminum, brass and magnesium die casting machines are available with the innovative GREEN LINE system, a new reference model of energy saving system for cold chamber machines.
