Why does the surface of my ABS glossy product have flow marks?

Recently, a customer asked: What should be done about flow marks on injection-molded ABS glossy panels?

A small suggestion:

1、Check whether a highlight masterbatch was used (our highlight masterbatch has improved flowability);

2、It is recommended to increase the mold temperature to [70-80℃];

3、Use [high speed and high pressure] for injection.
