Plunger Lubrication Unit: Plunger lubricants are applied on the plunger tip or in the sleeve before molten metal is introduced, as the shot fills the sleeve and enters the cavity, it is possible to entrain some of the lubricants into the molten metal. The very high velocities in the gate promote turbulence and facilitate intimate mixing of metal droplets and vaporized plunger lubricant. It can result in porosity or form a stain on the surface of casting avoided.
