Summary:A movable die is fastened to a stationary die, a relationship between a contact force of an injection nozzle to an injection hole of the stationary die and a closeness is investigated, the injection nozzle is brought into press contact with the injection hole of the stationary die by a contact force achieving a predetermined closeness, and a lubricant is coated by a predetermined pressure. At this occasion, one end portion of a cavity is opened or air is exhausted from the end portion as necessary. The lubricant is coated as mist by being mixed with a compressed gas. Further, the lubricant is coated by maintaining constant a pressure difference between a pressure applied to the lubricant and an inner pressure of the cavity and a pressure difference between a pressure of the compressed gas and the inner pressure of the cavity.
