Pultrusion is a continuous molding process utilising the combination of premium quality fibreglass roving’s, mats and fabrics and resin systems.
The fibreglass is drawn through a resin bath thoroughly wetting and impregnating the fibre with the thermosetting resin. Polyester vinyl esters and phenolic resins are used.
The wetted fibreglass is pulled through a desired (geometric) shape and pulled into a heated steel die. The resin cures to a desired level inside the heated die forming the exact required putlruded profile or cross section. The shapes can be circular rod, angle section , round and square, hollow tube wide flange beam, I beam, channel. The cross section or profile is then cut to the standard length.
