WHERE RIM GETS ITS NEW MOMENTUM

This paper reports on recent advancements in reaction inspection molding (RIM) technology. It is predicted that in the not too distant future more than 20% of all plastics will be processed on reaction injection molding (RIM) equipment - and they won't be just today's nonreinforced urethanes. This swing to RIM processing is getting its momentum from a number of sources. They include practical new reinforced RIM systems, automated equipment that's simpler to operate and more productive, and alternative RIM materials. Emphasis is placed on total process control with the use of microprocessors. Design details of metering and mixed equipment are given. Economic considerations are included.
