Therefore, there is an advantage that the waterproof packing can be manufactured at a low cost.
  • the method for manufacturing a waterproof packing according to the present invention does not require injection of synthetic resin into a narrow space in the mold as in the case of rim molding, so that a complicated and precise mechanical mechanism is not required.

Abstract

Selon la présente invention, par la fabrication d'une garniture étanche vis-à-vis de l'eau par un procédé simple, la garniture étanche vis-à-vis de l'eau est fournie à un coût aussi bas que possible. Un liquide de résine durcissable aux ultraviolets (16) remplit les rainures de moulage (12) formées dans une surface de moulage d'un moule (10), le liquide de résine durcissable aux ultraviolets (16) dans les rainures de moulage (12) étant irradié par une lumière ultraviolette, et une garniture étanche vis-à-vis de l'eau (20), qui est obtenue par irradiation du liquide de résine durcissable aux ultraviolets (16) dans les rainures de moulage (12) par la lumière ultraviolette, est retiré à partir des rainures de moulage (12). Les rainures de moulage (12) peuvent être formées sur le même plan ou sur une surface incurvée, ou peuvent être formées sur une surface irrégulière. De plus, une lumière ultraviolette peut être irradiée tandis que les rainures de moulage (12) sont remplies par le liquide de résine durcissable aux ultraviolets (16), ou une lumière ultraviolette peut être irradiée après que les rainures de moulage ont été remplies.
