Expandable mandrel
Foam sheet extrusion expandable mandrel was developed to considerably reduce time and production costs of foam extrusion by changing the sheet width without stopping the foam extruder or breaking the EPE foam!
The diameter – circumference change is done instantly by simple manual regulation of expansion, no electric mechanism inside.
The expandable mandrels of different ranges are air-cooled and suitable for extrusion of thin low density epe foam sheets.
