Riverdale Global (RG), based in Aston, Pennsylvania, has developed the RGInfinity™ material handling system that automatically refills one or more liquid color drums during the molding or extrusion process. This eliminates downtime for switching drums and reduces the occurrence of transitional or off-specification product with little or no color.
In addition, to prevent any occurrence of uncolored product, each drum is mounted on a Riverdale Gravimetric Stand, which monitors the weight of color in the drum and signals a pump valve on the tote when the drum is nearly empty and again when it is full.
