ABOUT THE NUMEROUS COST AND PROCESSING ADVANTAGES OF THE MICROCELLULAR FOAM INJECTION MOLDING PROCESS FOR THERMOPLASTICS MATERIALS IN THE AUTOMOBILE INDUSTRY
A. Oprea-Kiss, I. Kiss
Today one of the goals of the automobile industry is to reduce weight. And physical foaming has already demonstrated its potential in this sector, improving the value and performance of applications under the bonnet: engine and gearbox cases, inlet air filters, cockpits, radiator baffles and so on. Around the world, the microcellular injection molding (MuCell) is used in thousands of applications in the automotive, packaging, technical molding, office machinery and electric and electronic component industries. The research opportunities purpose is to obtain even lighter pieces, with greater dimensional stability and with an excellent surface finish, in other words, perfect plastic parts. More component functionality with reduced weight, and cost control at the same time: MuCell is a process to physically foam thermoplastics, which combines technical and economic objectives. Besides weight reduction, it also provides improved dimensional stability of the moulded parts.
