  1. The reason for the poor gloss: the low temperature outside the nozzle, long molding cycle, more titanium dioxide in the masterbatch, and poor pigment dispersion in the masterbatch;

Solution: Increase the nozzle temperature and shorten the molding cycle. Reduce the titanium dioxide in the masterbatch particles and improve the pigment dispersion in the masterbatch particles.

  1. Reasons for uneven color: high temperature of material cylinder, long molding cycle and poor resin compatibility;

Solution: Reduce the temperature of the feed tank and use a carrier with good compatibility.
