Vacuum core process – special technology for large cores
On request of Chinese and American waggon, casting producers SUZHU developed the special Vacuum core process technology for mass production of monolith central cores for bolster and frame casting, which is also used for production of other large cores.
Advantages of the Vacuum core process are decrease of content of binder up to 50% and decrease of Amin or CO2 consumption. In practice, the process works with Amin-Technology as well as with Water glass-Technology, which is mostly favoured by steel foundries.
Core package moulds
Suzhu developed its new machine Z84800 with shooting head volume of 800 litres. The first machine started work in summer 2015. The technology is based on Cold Box Amin process, optional with Vacuum.
