Expandable Polystyrene Beads

Quickdraft provides eductor units and complete pneumatic systems to convey expandable polystyrene beads. Typical systems convey the beads from the expander to a storage container, or to multiple dispensing bags or hoppers above injection molding machines. The beads are gently pulled from the hopper at the expander by negative pressure and discharged with light positive pressure into the storage container, dispensing bag or hopper. The conveying air volume and duct size is selected to achieve your desired material flow rate.

Our Quickdraft eductor unit is ideally suited to convey the beads as there are no moving parts in the conveying flow path to damage the beads. This differs greatly from an in-line material handling fan. Our customers have confirmed to us many times over the years that in-line fans damage the beads and change their density as the beads pass through the impeller. They have also confirmed to us that our eductor unit reduces or eliminates the problems associated with using in-line fans.
