Injection molding, a polymer processing technique that converts thermoplastics into a variety of plasticproducts, is a complicated nonlinear dynamic process that interacts with a different group of variables, including themachine, the mold, the material, and the process parameters. As injection molding process operates sequentially inphases, we treat it as a batch process. The review paper discusses the batch nature of injection molding and identifies thethree main objectives for future development of injection molding: higher efficiency, greater profitability, and longer sustainability. From the perspective of system engineering, our discussion centers on the primary challenges for the batchoperation of injection molding systems: 1) Model development in face of product changes, 2) Control strategies in face ofdynamic changes, 3) Data analysis and process monitoring, and 4) Safety assurance and quality improvement, and thecurrent progress that has been made in addressing these challenges. In light of the advancement of new informationtechnologies, this paper provides several opportunities and encourages further research that may break existing capabilitylimits and develop the next generation of automation solutions to bring about a revolution in this area.
