摘要
Novel industrial product, characterised in that it consists of an elongate hollow component, one of the dimensions of which, measured in a first direction, is greater than at least ten times another dimension, measured in a second direction, the ratio of the hollow cross-section to the total cross-section is of the order of 40 % and the ratio of the hollow cross-section to the solid cross-section is of the order of 60 %, the said hollow piece being obtained by application of the technique of moulding by Central Injection of pressurised Gas (CIG) to semicrystalline and amorphous plastics chosen from polyamides (PA), ABS (acrylonitrite/butadiene/styrene), SAN (styrene/acrylonitrile), ASA (acrylonitrile/styrene/acrylate), PPE (polyphenylene ether oxide), PC/ABS (polycarbonate/acrylonitrile/butadiene/styrene), PP (polypropylene) and, preferably, terephthalate polyesters, possibly filled with glass fibre.
