EZ SERIES - HOT CHAMBER

Hybrid die-casting machines from 90 to 140 tons for the injection of zamak and magnesium
« Home « Products « Machines | EZ SERIES - HOT CHAMBER

The production of Colosio electric hot chamber machines - for the die-casting of zamak and magnesium alloys – ranges from 90 tons up to 140 ton closing force. Fully digital, they are equipped with memory of the molds (Coltrol System). The control of the data and their recording and saving on PC, allow to repeat the parameters of pressure, speed and stroke optimal for each single mold, allowing to visualize the injection curves relative to each casted part (Fullcoltrol).

The closing group is inclined by 5 ° to facilitate, after the injection, the reflux of the liquid metal towards the metal bath. The separation of the nozzle from the mold takes place before opening, in order to guarantee the breaking of the final part of the casting slug in the most suitable position. The eZ series of machines differs from the traditional PFZ series because it is equipped with a closing system operated by a servomotor and a worm screw.
The new eZ series offers:

FASTER CYCLE TIME
Thanks to the contemporary opening of plates and central ejection movement
SAVING OFWATER AND COOLING ENERGY
Absence of hydraulic fluid cooling system
SIMPLIFICATION OF HYDRAULIC SYSTEM
Purely electric closing / opening system. Only injection and extraction are hydraulic
SIMPLIFIED MAINTENANCE
Reduced need for maintenance thanks to the advanced design of the machine
QUICK AND PRECISE INJECTION
Optimization of the injection process to reduce the air in the castings
GREATER PRODUCTIVITY
Quick, precise, easy to use

 

On request, the machines can be equipped with a REAL TIME injection system with closed loop of speed and pressure. The doors of the Colosio machines run on two external central guides. There is therefore no limitation when mounting bulky molds, and the doors movement unit, placed outside the machine, is kept fast, clean and efficient.

The machines are equipped with an automatic centralized lubrication system for all moving parts, with programmable frequency and duration from the panel and signaling of any faults by means of a warning light.
Both PFZ and eZ machines are already equipped with a furnace - with a special alloy crucible - that the Customer can choose either electric or combustion. The siphon extension is heated by a gas burner or, upon request, by electric heating. The cleaning of the working space, then, is assured by mounting the machine on a tank for collecting waste fluids. Finally, a fumes extraction hood allows the machine to be connected to the centralized suction system. On request, the machines are available with the innovative GREEN LINE system, a new energy and operating reference model for die-casting machines.
