Abstract
A powder-containing oil-based lubricant for die contains 60 to 99% by mass of an oil-based lubricant consisting of oil, 0.3 to 30% by mass of a solubilizing agent, 0.3 to 15% by mass of an inorganic powder and 7.5% by mass or less of water, the lubricant being electrostatically applied to a die. The powder-containing oil-based lubricant may be applied to a die by electrostatic spraying. The electrostatic spray apparatus includes a device that imparts static electricity to the powder-containing oil-based lubricant and an electrostatic spray gun installed on a multi-axis robot.
