This course is designed to provide learners with a comprehensive understanding and practical competence in the use of computer-aided engineering (CAE) tools for the analysis of thermoplastic moulding processes. It covers the simulation of key injection moulding stages—filling, packing, and cooling—and their influence on the final product quality. Through numerical modeling, students explore common manufacturing defects such as air traps, weld lines, sink marks, incomplete filling, and thermal deformation etc. Emphasis is placed on evaluating the effects of part geometry, material rheology, and processing parameters on defect formation and flow behavior. Learning outcomes: upon completion, students will be able to employ various CAE platforms to simulate plastic moulding processes, identify and interpret defect-related phenomena, and optimize part and mould designs at the early stages of development to improve product quality and manufacturing efficiency.
Apply CAE tools to model and interpret the results of plastic injection moulding processes. Simulate all key technological stages of the moulding cycle: cavity filling, packing pressure, cooling phase, and part deformation (warpage). Identify and predict the most common manufacturing defects, including air traps, weld lines, sink marks, short shots, and uneven cooling. Evaluate the influence of mould geometry, gating and runner system layout, cooling channel distribution, and cycle time on part quality and production efficiency. Analyze key rheological and thermal properties of materials—such as viscosity dependence on shear rate and temperature, thermal conductivity, and coefficient of thermal expansion. Make data-driven design decisions at the early development stage, such as modifying wall thickness, adjusting gate placement, or optimizing the cooling system. Apply CAE to complex scenarios within the plastic moulding process.
