1, gloss is not good reason: nozzle outside temperature is low, the molding cycle is long, masterbatch used in titanium pigment, pigment dispersion in the masterbatch.

Solution: increase the nozzle temperature, shorten the molding cycle. Reduce the titanium pigment color masterbatch, improve pigment dispersion in the masterbatch.

Two causes: uneven, colour and lustre of material cylinder temperature is high, the molding cycle is long and resin compatibility is bad.

Solution: to lower the cylinder temperature, USES the carrier with good compatibility.
