ABSTRACT
Microcellular injection molding is an emerging process capable of producing foamed parts with many advantages, such as material, energy, and cost savings, as well as enhanced dimensional stability. A novel Supercritical fluid pellet Injection Molding Foaming (SIFT) technology for producing injection molded parts with a foamed structure has been developed. The idea is to pre-load an atmospheric gas, such as carbon dioxide (CO2) or nitrogen (N2), into the plastic pellets to act as a physical blowing agent. Processing those gas-laden and ready-to-foam pellets using regular injection molding machines lowers equipment costs without sacrificing the production rate, thus making it a viable and attractive candidate for the mass production of foamed injection molded parts. This process is akin to employing a chemical blowing agent (CBA) without the typical concerns of chemical residual. The shelf life of the gas-laden pellets is an important factor in this process because the effective gas content may vary with time due to gas desorption, which could lead to variation in part quality. In this paper, research results on (1) comparison of shelf life using CO2 and N2 as the blowing agent, (2) shelf life of CO2-laden pellets, and (3) evaluation of effective gas content in the CO2-laden pellets are presented.
ABSTRACT
Control system is the brain of injection molding machine, the control performance determines the quality of the molding process. To ensure a good part quality, it is crucial to design an accurate, robust and intelligent control system. An advanced control system has been developed by the Center for Polymer Processing and Systems (CPPS) at Hong Kong University of Science and Technology (HKUST). It can be applied directly to the existing injection molding machines with minimal machine modification. This paper illustrates the industrial test results of this control system on different injection molding machines. The repeatability and accuracy of the controller has been demonstrated. Process monitoring and fault diagnose is another important feature of the control system. Using advanced stage-based principal component analysis algorithm, the controller can provide reliable monitoring of the injection molding process.
