Pre-expanding process is to foam the EPS granulates(Expanded polystyrene resins) in tanks with hot steam.
Our pressurized batch type pre-expanding system can decrease in a deviation of specific gravity at large and remaining moisture. We have improved it’s workability by enabling an operator to control the temperature and pressure easily during the expansion process.
A high density pre-expander or an automatic gravimeter can be included and the silo can be divided into manual type, semi-automatic type and automatic type.
Also, it will be composed as to minimize the problems related with static.
