Gas-assisted injection molding process is much complicated,the process parameters have multiplied. In this paper, a product with typical character of gas-assisted injection molded part is employed as the object of study. With the mould of gas-assisted injection molding and MPI/3D GAS in Moldflow software,the influence rule of the 6 important process parameters on gas penetration length in gas-a...

1 INTRODUCTION The technical requirements of precision injection molded components demand a heightened level of process performance, and with corresponding process monitoring and control technologies. To obtain the desired critical to quality attributes (CTQs) of the molded products, the injection molding process must be consciously designed such that the key process variables (KPVs) are observ...

During the last decades, society’s concern for the environment has increased. Specific tools like the Life Cycle Assessment (LCA), and software and databases to apply this method have been developed to calculate the environmental burden of products or processes. Calculating the environmental impact of plastic products is relevant as the global plastics production rose to 288 million tons in 201...

Injection molding technology continually develops, with major milestones including the introduction of the first thermoplastic materials, the reciprocating screw design, the first hot runner systems, engineering materials, the introduction of microprocessors for machine control, Computer Aided Engineering flow simulation software, and recently the application of expert systems for optimized mac...

Injection molding is one of the most important and common plastic formation methods. Combination of modeling tools and optimization algorithms can be used in order to determine optimum process conditions for the injection molding of a special part. Because of the complication of the injection molding process and multiplicity of parameters and their interactive effects on one another, analytical...

This paper presents the adaptation of a conventional injection molding process to the mass replication of polymeric microstructures with appropriate mold design and process control. Using wet-etched silicon wafers with microstructures on the surfaces as mold inserts, we have successfully predicted, improved and optimized the replication results. The flow behaviors of polymer melts in micro mold...

E. Ragan, J. Dobránsky, P. Baron, M. Kočiško, J. Svetlík, Technical University in Košice, Slovakia Most plastic parts used in automobile production are manufactured by injection molding. Their quality depends also on taking out molding and on the manipulators for it. Task of this contribution is to theoretically describe a transport of molding at taking out after injection molding in relation o...
