Part 72:flow marks tell on moldmarer

摘要

Irecently received a couple of parts and a runner system to examine.The parts had separated from the runner so I gave them a quick once-over,and then took a look at the runner.It seemed to be sized OK with a subrun-ner diameter of .250 inch and the main runner .312 inch.Maybe they were a little larger than they needed to be,but that was better than being too small.
