Pultrusion is a continuous process of roving, or mat/ roving bundles, which are drawn through a resin
impregnated bath to coat each fiber with a specially formulated resin mixture.
The impregnated fibers are then drawn through a heated die which forms the desired cross section.
Curing of the thermosetting resin is initiated by heat in the die and catalyst in the resin.
The rate of reaction is controlled by heating of the die. The resulting high unidirectional strength profile is cut to
length and is ready to be used in another Oglaend FRP cable management system.
