Abstract
The provision of a durable, slick sliding surface on metal faces of plastic forming extrusion apparatus such as extruder nozzles and dies. The durable, slick sliding metal surface is provided by burnishing and heat treating a polysiloxane fluid on the face of the metal. The burnishing comprises vigorous rubbing of the polysiloxane fluid treated metal face with a material relatively softer than the metal face being treated, effectively over the entire surface treated.
