The invention relates to the application of moisture-free basis powder or grain lubricant in die-casting pure copper and the cooper squirrel-cage rotor of high copper containing alloy induction motor, which belongs to nonferrous metal process technology field. The invention is the application of making moisture-free basis powder containing zinc stearate or grain lubricant as punch or surge chamber lubricant and the application of making moisture-free basis powder containing zinc stearate or grain lubricant as demoduling agent of the module. The invention adopts regular plunger piston lubricant supply equipment and static blow gun spray finishing way to spay finishing. The practical application shows that: with adopting the application in the invention, the qualification rate of the copper rotor product and the service life of the die-casting device are both improved obviously.
