PROCEDURES AND FORMAL PRODUCTION FOR THE MANUFACTURE OF RAILWAY HEADLAMPS FOR AIRCRAFT TRAILERS

摘要

A polyamide resin containing reinforcing fiber is dry blended with a polyamide resin containing no or less reinforcing fiber. A polyamide resin containing 15 to 50 % by weight of reinforcing fiber thus obtained is used as a material. By using a moving type core having a two-stage structure including a large diameter moving core and a small diameter moving core, a tubular hollow molded body 17 is formed, and redundant portions 18 and 19 are cut and removed.
