Abstract
An exclusive molding method for producing cloth-based parts of loudspeaker is employed to move a resin-dipped and dried cloth roll to pass intermittently through a heating device and a mold set in order, so that the cloth roll is preheated then molded into shape of parts and cut into the desired parts with a heightened working efficiency.
Claims
exact text as granted — not AI-modified1 . An exclusive molding method for producing cloth-based parts of loudspeaker, comprising:
(a) Providing a resin-dipped and dried cloth roll; (b) Moving the cloth roll to pass through a heating device and a mold set intermittently in order, such that the cloth roll is preheated by the heating device then molded to show the shape of parts; and (c) Cutting the molded cloth into pieces to obtain the desired cloth-base parts.
2 . The exclusive molding method according to claim 1 , in which, after passing through the heating device, the cloth roll is leveled by a leveling device before been moved to the mold set.
3 . The exclusive molding method according to claim 2 , the leveling device comprises at least of a pair of rollers for pinching and flushing the cloth roll.
4 . The exclusive molding method according to claim 1 or claim 2 , in which the preheating temperature provided by the heating device is in the range of 150° C.˜200° C.
5 . The exclusive molding method according to claim 1 or claim 2 , in which the preheating time is in the range of 10 ˜ 15 seconds.
6 . The exclusive molding method according to claim 1 or claim 2 , in which cloth-based parts are formed by the mold set under room temperature.Cited by (0)
