HOT CHAMBER MAGNESIUM

The production of spare parts is carried out with specific high quality materials and using thermal treatments that have been specifically developed by Brondolin.
Work conditions (at temperatures between 620°C and 650°C) require particularly high resistance to both abrasion and heat. 
For these applications, the goosenecks are realised using the most advanced casting technologies. All the other accessories - plungers, rings, nozzles, tips and rods - are realised by forged bars. 
As with the zinc hot chamber, Brondolin’s electric nozzle (European patent N° 1354650) has made it possible to optimise the pressing process. Perfect temperature control also makes it possible to considerably improve the quality of pressed castings, thereby reducing the percentage of scraps.
