Abstract: This study investigates the impact of injection angle on polylactic acid (PLA) wire coating performance, focusing on flow dynamics, heat transfer, mass density, and pressure distribution.Three angles: 30°, 45°, and 60° were assessed for their effects on coating characteristics.At 30°, the flow is smooth with minimal turbulence, ensuring consistent deposition.The 60° angle increases velocity and material penetration but risks turbulence and uneven coating.The 45° angle optimally balances material mixing and flow stability.In terms of heat transfer, the 30° angle concentrates heat near the injection point, creating a steep thermal gradient, while the 60° angle disperses heat more broadly but with lower intensity.The 45° angle ensures uniform heat distribution, improving energy efficiency.Regarding mass density, the 30° angle favours localized deposition, ideal for concentrated applications, while the 60° angle promotes broader distribution with reduced concentration.The 45° angle optimises density uniformity and maintains structural integrity.Pressure distribution follows similar trends, with 30° and 60° angles causing uneven deposition, whereas the 45° angle ensures balanced pressure distribution.In conclusion, the 45° angle offers superior performance across all parameters, providing an optimal balance of efficiency, uniformity, and structural integrity, thus enhancing PLA wire coating quality for sustainable engineering applications.
