METHOD OF FORMING LUBRICATIVE PLATED LAYER ON VISCOUS LIQUID FEED NOZZLE AND VISCOUS LIQUID FEED NOZZLE

摘要

In a viscous liquid feed nozzle having a nozzle body provided with a thin and long hole with a front end serving as a feed port, a lubricative plated layer is provided by immersing the liquid feed nozzle in a plating tank containing a lubricative plating solution and forming, by electroless plating, the lubricative plated layer at least on the inside and outside of the feed port.
