If considering a venturi type of loader, be aware that during the loading time, material can be lifted from the material hopper due to the small amount of material storage in micro feeders. As the plastics industry pushes toward lower-rate feeding require- ments, it will be important to work with your equipment supplier to confirm minimum and maximum feeding rates that can be achieved with their feeding technology. If you use both pellets and powders, does the equipment supplier offer a single feeding solution for both types of material, or do they require two separate feeders? How consistently can your material be fed? Can your material supplier offer better constancy in material size if needed? @plastechmag 47 Plastics Technology M I C R O F E E D I N G
