Are your color mixing nozzles helping or hurting your productivity?
The most common use of mixing nozzles is to deliver a more uniform distribution of color additives so part appearance is enhanced and the scrap rate is reduced. Mixing nozzles can also increase the usable level of regrind. All mixing nozzles do these things to varying degrees, but certainly some perform more effectively and efficiently than others. In fact, some poorly designed mixing nozzles are so difficult to work with, they can actually hurt your bottom line.
+ GOOD, WELL DESIGNED MIXING NOZZLES such as the New EZ Flow from IMS allow quick screw recovery and low temperature settings which can result in cycle times and energy consumption being minimized.
+ Poorly designed, all purpose mixing nozzles sometimes make it necessary to adjust process parameters to overcome poor performance. For example, you can adjust machine back pressure, but this only slows screw recovery, and in many cases increases total cycle time. Mixing problems may also be overcome by increasing temperature settings for the barrel and nozzle. This often improves the melt quality, but it also increases part cooling time and the use of electricity. Inconsistent melt temperatures may result in unacceptable "Seams" or "Flow Lines" in the molded parts.
HOW MIXING NOZZLES WORK
Disruption of the laminar flow through the nozzle creates turbulent flow changes forcing the layers of plastic to collide into one another.
There are two main designs that create this turbulent flow:
A.) Designs that use increasing and decreasing pressure flow moving the polymer into areas of greater volume then forcing the flow through areas of lesser volume. The EZ Flow units, shown below, are examples of this type of flow action and are recommended for unfilled stable polymers like nylons, polypropylenes and polycarbonates for the distribution of non-fiber additives like color.
B.) Designs that displace the laminar flow layers, moving the center flow to the outer edges and back to the center. Typically this method is not as effective as pressure designs in their blending action, but these designs are much gentler allowing their use on shear sensitive materials or other resins like Nylon G/F with fiber additives. The IMS In-Line Color Mixing Nozzles are examples of this type of action.
Note: NO SINGLE MIXING NOZZLE CAN BE EFFECTIVE IN ALL APPLICATIONS
That’s why IMS now gives you
11 different size/style mixing nozzles from which to choose
The effect of flow rate on injection pressure is based on the flow volume through the mixing elements. The proper size unit will create little, if any, pressure drop through the mixing element. Each element design offers recommendations as to the machine’s shot size limitations for the element. If pressure drop creates a molding problem, moving to a different design in the same size unit with a higher flow volume may solve the problem. If not, a large size unit may be required.
