Abstract: A viscous liquid feed nozzle has a nozzle body having a thin and long hole with a front end serving as a feed port. The nozzle is used with a viscous liquid feed unit to feed a viscous liquid such as a viscous adhesive from the feed port. The nozzle has a lubricative plated layer at least on the inside and outside of the feed port. The lubricative plated layer is formed by electroless plating by immersing the nozzle in a plating tank containing a lubricative plating solution. A base end of the nozzle body may have a wide port. In this case, the lubricative plated layer is formed by immersing the nozzle body in the plating tank containing the lubricative plating solution so that the lubricative plating solution enters the wide port and by applying pressure or gravity to the lubricative plating solution in the wide port to pass the lubricative plating solution through the thin and long hole of the nozzle body and discharge the same from the feed port. The viscous liquid feed nozzle with the lubricative plated layer is capable of stably feeding a very small quantity of a viscous liquid.

Abstract translation: 粘性液体供给喷嘴具有喷嘴体，该喷嘴主体具有薄且长的孔，前端用作进料口。 喷嘴与粘性液体进料单元一起使用以从进料口进料粘性粘合剂如粘性粘合剂。 喷嘴至少在进料口的内部和外部具有润滑镀层。 通过将喷嘴浸入含有润滑电镀液的镀槽中，通过无电镀形成润滑镀层。 喷嘴体的基端可以具有宽的端口。 在这种情况下，润滑镀层是通过将喷嘴体浸入含有润滑电镀溶液的镀槽中而形成的，使得润滑电镀液进入宽端口，并通过向广泛端口的润滑电镀溶液施加压力或重力 使润滑电镀液通过喷嘴体的细长孔并将其从进料口排出。 具有润滑镀层的粘性液体供给喷嘴能够稳定地供给非常少量的粘性液体。
