Effect of injection molding process on gloss and chroma of ABS resin
The effects of injection speed,injection pressure and holding pressure on the gloss and chrominance of ABS resin were studied by different injection molding processes.The results showed that the sensitivity of ABS resin gloss to injection pressure was greater than that of injection speed.With the increase of injection pressure,ABS gloss was increased by 2.2％.With the increase of holding pressure,ABS gloss was increased by 1.7％.Injection speed had little effect on ABS gloss.When injection speed and injection pressure were respectively increased,ABS whiteness first increased and then decreased.The yellow index decreased first and then increased.Injection speed had great influence on whiteness,and the maximum fluctuation was 3.8％.The holding pressure had little influence on the colorimetry of ABS resin.
