Home | Services: Zamak Die casting
The hot chamber die casting process was named after the injection system used. The melting furnace being placed next to each press allows the raw material to be melted and kept at the correct temperature during the die casting process which takes place directly inside the press. Tagliapietra s.r.l. has different modern machines and technologies available to casting zamak with precision and attention to detail:
Starting from the closed mould, the press controls, through pre-selected parameters, the movement of the injection piston which press the melted metal in the chamber, pushing it to go back up towards the mould cavity passing through the siphon and the nozzle.
Once the mould cavities have been completely filled and wait a defined time for the solidification phase, the press will open the mould and activate the ejectors panel to extract the casting.
A light film of mould lubricant agent is applied to the two halves of the mould and the cycle is ready to start again.
In terms of last generations machines Tagliapietra s.r.l. has complete digital presses available, equipped with a closed-loop management system and with the possibility of applying vacuum system technology where necessary.See the zamak alloys that can be processed by Tagliapietra s.r.l.
