Abstract
Manufacturing variable and/or singular property products, such as a tubing, in a tip-and-die assembly, where intermittent acting material injectors are used. Two or more injectors take turns making material shots to maintain a continuous material stream. A singular flow controller regulates the flow for all material streams coming from the injectors.
