Extrusion (November 01, 2009)

A new super thermal conductive mandrel technology developed by Acrolab Ltd. is designed to permit curing of filament-wound pipe and tube sections without the need for cure ovens by heating the mandrel uniformly, while rotating, using induction heating.

The Isomandrel design consists of an internal process within the mandrel that enhances its thermal conductivity and thermal reactivity. The process permits heat to be applied in a localized concentration that is then rapidly and homogeneously redistributed over the complete mandrel-working surface.

Isomandrel technology, when coupled with induction heating, permits the mandrel and filament winding to continue rotating while being heated to an optimum controlled temperature to effect cure. This heating can occur while the assembly is still rotating in the winding machine or on a rotating fixture within the manufacturing cell.

By providing high thermal energy uniformly over the entire mandrel surface outward through the filament winding, the cure is completed in much shorter time with less energy while providing a significantly more uniform cure and resin-rich I.D.
