Abstract
The most important plastic resins used for wire coating are polyvinyl chloride (PVC), nylon, polysulfone, and low-/high-density polyethylene (LDPE/HDPE). In this article, the coating process is performed using elastic-viscous fluid as a coating material for wire coating in a pressure type coating die. The elastic-viscous fluid is electrically conducted in the presence of an applied magnetic field. The governing non-linear equations are modeled and then solved analytically by utilizing an Adomian decomposition method (ADM). The convergence of the series solution is established. The results are also verified by Optimal Homotopy Asymptotic Method (OHAM). The effect of different emerging parameters such as non-Newtonian parameters α and β, magnetic parameter Mand the Brinkman number Br on solutions (velocity and temperature profiles) are discussed through several graphs. Additionally, the current results are compared with published work already available.
Highlights
When studying the boundary layer behavior of a viscoelastic fluid on a continuous stretching surface, it is important to analyze the extrusion of the polymer, stretching of plastic films, optical fibers, and cables
The simplest and most appropriate process for wire coating is the coaxial extrusion process that operates at the maximum speed of pressure, temperature, and wire drawing

Summary
When studying the boundary layer behavior of a viscoelastic fluid on a continuous stretching surface, it is important to analyze the extrusion of the polymer, stretching of plastic films, optical fibers, and cables. Shah et al [20] studied the elastic-viscous fluid for wire analysis in a pressure-type coating die. Researchers have devoted considerable attention to the study of MHD flow problems, focusing on non-Newtonian fluids because of its broad applications in the fields of engineering and industrial manufacturing. Some examples of these areas are energy generators. A survey of the literature indicates that much attention is given to elastic-viscous fluids, especially from the polymer industry (polymer melts), in the use ofwires and optical fiber coating Being inspired by such practical applications, several authors discussed the elastic-viscous fluid flow. Solution is by shown and discussed by usingvalues graphsofofdifferent numerical values ofofdifferent
