Abstract

PURPOSE:To get rid of decrease in mechanical physical properties when a resin strand is formed and to obtain a rack gear with high reliability, by adding proper amt. of elastomer to polyacetal and carrying out continuously a heat- crystallization process, a forming process and a heating process on the extrusion- molded resin strand. CONSTITUTION:A composite material where polyacetal is used as a base material and, a composite material wherein 5-60%, preferably 10-30% of urethrae modified polyacetal is then added is used. A molten resin is continuously extruded from a mold nozzle 2 as a resin strand 3 and passed through the first oil bath 4 at 80-160 deg.C for 30-90sec, and successively passed through the second oil bath 5 at 60-140 deg.C for 30-90sec. The semi-molten resin passed through there is passed through a gap between a rack gear roll 8 and an acceptor roll 9 at room temp. and specific projections and recesses are thereby formed and a rack gear 30 is continuously press-treated. The resin 31 where a rack gear 30 is formed is passed through an annealing treating bath 10 at 150-180 deg.C for 60-120sec and then through a washing bath 12 wherein degreasing treatment of the product surface is done.
