A gravimetric blender including a frame, a weigh bin, a device connected to the frame for sensing weight of the bin and any material contained therein, a mix chamber below the bin, connected to the frame, a piston for selectably releasing material in the bin downwardly into the mix chamber and an elastomer connecting a sensor device to the frame and damping transfer of vibration and shock motion therebetween. The method includes metering solid resinous materials until preselected weight of the respective materials are at the weigh station, metering liquid color until a pre-selected weight of color is at the weigh station, and providing the metered solid resinous materials and metered liquid color material to a mixing station for manufacturing processing via molding or extrusion.
