Abstract

Hot plate welding is a critical technique in the production of plastic parts, where precise control of welding parameters directly affects the quality and cost-effectiveness of the final product. In this study, we explore the theory of plastic welding, providing a detailed explanation of the process and the specific procedures employed in our production line, along with the equipment used. To identify the most influential factors on weld strength, three key parameters, melting time, melting temperature of the tube, and melting temperature of the plate were selected for analysis. A dedicated test method was designed, and optimization was performed using the One-Factor-At-a-Time (OFAT) approach and Minitab software. The results indicate that higher melting temperatures and prolonged melting times, within an appropriate range, enhance polymer chain diffusion, leading to increased weld strength in cylindrical plastic vessels. By integrating theoretical insights with experimental findings, this study provides optimized welding parameters that significantly improve the welding quality. The outcomes offer valuable guidance for achieving superior weld strength while maintaining production efficiency in plastic manufacturing processes.
