expanded polystyrene pre-expander / automatic



  • Options:

    for expanded polystyrene, automatic


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
