PFZ SERIES

Hot chamber

PFZ SERIES

Hot chamber die casting machines from 50 up to 320 tons for zink and magnesium die casting.

A design that arises from the encounter between speed and constancy of production

Each PFZ 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 closing unit is inclined to favor, after injection, the reflux of the liquid metal towards the metal bath. The detachment of the nozzle from the die occurs before opening, to ensure the breaking of the end part of the slug in the most suitable position.

The standard machine is equipped with 2 injection positions. The automatic system allows you to hydraulically lift the entire closing unit to use the machine in the desired position. The two-phase injection is divided into a first “under pump” phase and a second fast “under accumulator” phase.

The injection position reading system is contactless and uses transducers without sliding contacts, avoiding wear due to typical and continuous contacts.

Product

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 hot chamber machines – specific for the die casting of zink and magnesium – ranges from 50 up to 320 tons of clamping force.

Solutions to give competitive advantages to our Customers


On request, hot chamber machines for magnesium and zamak die-casting can be equipped with a REAL TIME closed-loop speed and pressure injection system.

The safe and functional ‘pre-filling’ option allows you to fill the feed channels before the nozzle before closing the machine, to reduce the cycle time as much as possible.

The gates of each Colosio die-casting machine slide on two central external guides, ensuring that there is no clutter when mounting bulky moulds. In addition, the gate movement unit located outside the machine is kept fast, clean and efficient.

The machines are equipped with an automatic centralised lubrication system for all moving parts, with frequency and duration programmable from the control panel and signalling of any faults by means of a warning light.

The diecasting machines for zamak and magnesium are already equipped with a furnace with a special alloy crucible with a choice of electric or combustion power supply. The siphon is machined from a steel block and comes complete with a sleeve with a cylindrical hot coupling. The extension-siphon is heated by a gas burner or, on request, by electric heating. Cleaning of the cell’s workspace is ensured by mounting the machine on a fluid collection tray (optional). Finally, a fume hood allows the hot chamber diecasting machine to be connected to the centralised suction system.

Environment

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.
