The Troubleshooter Part 121: Give the gates some room

摘要

Lucky me: I received two deliveries from FedEx in one day. Perhaps this means the economy is picking up a little bit. I hope so, because it has been slow for much too long. I opened the first package and found a small runner with parts attached to each of the four edge gates. Overall I could see that it was a two-plate cold runner tool and the material was a crystalline material of some kind—probably an unfilled nylon 6/6, from the slippery feel of the part surface and the limited flexibility I felt when I flexed the runner and the cold sprue. Each of the four parts was identical, so this was a multicavity mold.
