- Hydrodynamic coating of wires and wire robs is a process, whereby a metal continuum is coated by passing it through a hydrodynamic pressure unit filled with polymer melt. The geometry of the coating unit is parallel (stepped) in the first section while becomes converging exponential the second part. Theoretical analysis has been found in literature and applied to predict the pressure distribution in the complex pressure unit. In this paper a mathematical model has been developed for the pressure distribution within a complex geometry pressure unit for hydrodynamic coating of wires and wire robs. Theoretical results are obtained for different continuum speeds in terms of the changes in viscosity, shear stress and pressure distributions within the unit, such results will help in assessing and evaluating the performance of such coating units
