<p>The method involves the production by die-casting of steam iron plates (10), each featuring three internal ducts (11, 12, 13), respectively first, second and third, that run side by side, and are connected so that they follow on from one another by means of two ducts (16, 17), sixth and seventh respectively, as well as two further ducts (14, 15), fourth and fifth respectively, that are connected so that they follow on from one another, of which the fourth (14) is connected to the inside end of the third duct (13). The first (11), second (12), third (13), fourth (14) and fifth (15) ducts are produced during casting by means of cores, whilst the remaining ducts (16, 17) as well as an extended portion (15b) of the fifth duct (15) are produced by drilling after the casting is over. The base of the plate (10) features equidistant holes (20), that are produced so that they correspond with the fourth (14) duct and the extended portion (15b). The holes along the edge of the plate (10), corresponding to the second (12), third (13), fourth (14), fifth (15), sixth (16) and seventh (17) ducts are closed off, leaving the hole of the first duct (11) to be connected to the steam supply pipe.</p> |
