ADVICE FOR A QUICK COLOR CHANGE

3 Professional Advice for a Quicker Color Change

One of the major headaches processors experience is color crossovers. Changing colors is challenging no matter the process. Fortunately, there are a few suggestions that, in our experience, significantly ease your life while you're dealing with a challenging shift.

Keep these three suggestions in mind when purging during color changes.

1) High back pressure

2) Elevated screw RPM

3) Raise the temperature of the nozzle 10-20°C

High back pressure:-The most crucial thing to bear in mind while changing a color is to apply enough back pressure to keep the screw forward all the time. This ensures that the purging agent may clean the screw flight's trailing edge and operate throughout the whole length of the screw. This area won't be fully cleaned without enough backpressure.

Elevated screw RPM:- The second thing to keep in mind is that mechanical purging compounds clean your machine by using shear and friction. As much as is safe and practical, increase the screw speed. High back pressures and high screw speeds will produce the most shear and friction throughout the purging process for getting best results.

Raise the temperature of the nozzle 10-20°C:- The nozzle body and nozzle tip are the final common hang-up region for contamination and deterioration. An effective solution for this problem is to raise the nozzle's temperature by 20°C when the color change begins.

The additional heat generated during the purge process will cause the purging compound to displace the degrading nozzle material. This will lead to a purge that is more successful.

You will be more productive, effective, and efficient if you adhere to these suggestions.
