Vibratory tray feeder consistently feeds success
An inline compounder installs a vibratory tray feeder to successfully feed long-fiber fiberglass into an extrusion process with increased accuracy and consistency.
"The difficulty with feeding longfiber fiberglass is that it has a very high aspect ratio," says Charles Weber, president of Composite Products Inc. (CPI), Winona, Minn. "It's like trying to feed a bunch of toothpicks into a machine at an even feedrate. Our fiberglass is comprised of relatively stiff bundles ranging from 1/2 to 1 inch long that clog and bridge and aren’t conducive to being processed in typical material handling systems. We needed to find a way to accurately and consistently feed the fiberglass without breakage and constant downtime."
