摘要

The pressure hose manufacturing method (10) involves injection molding (14) of a hose tubular element (16), in which a thermoplastic elastomer (26) is processed. A fabric tube (30) made of aramid is mounted (28) on the outer side of the tubular element. Another hose tubular element (34) is injection molded (32) around the former tubular element, in which another thermoplastic elastomer (42) is processed, and the fabric tube is drawn on it. The drawn fabric tube is cut at one of its end sections.
