Plasto-hydrodynamic investigation of the lubrication and coating of wire using a polymer melt during drawing.

Wire drawing has been the subject of much research and development but there is evidence that conventional methods of lubrication may have reached the limit of development, This project investigates the advantages and problems of lubricating the wire drawing operation hydrodynamically using a polymer as the lubricant. The experimental results are compared with results generated by an existing theory and the theory developed in the light of those experimental results. Design equations are suggested based on the modified theory.
