Processors will often try to apply

Processors will often try to apply a “Band-Aid” to the problem of poor melt uniformity. These “Band-Aid” approaches include using mixing nozzles and mixing tips. These nozzles and tips have mixing elements that will provide additional shear and mixing as the material travels through these locations. These items can help with color concentrate mixing but will not be as effective as having a dedicated mixing screw. When using mixing nozzles and mixing tips the machine will experience additional pressure drop through the nozzle due to the restriction to flow.
