Background, Motivation and Objective The key process condition parameters of conventional injection molding (IM) process include temperature of barrel and mold, screw back-pressure and rotation speed of plasticizing unit, etc. The process monitoring at mold side has been well discussed. However, the resin flow characteristics at barrel, especially at nozzle, are still under investigation. The most utilized sensors for IM process monitoring are temperature and pressure sensors. These sensors may have some limitations for application, such as limited machine space, direct contact with the substrate, operation environment of room temperature, etc.
