INJECTION MOLDING: How to Tell If Your Non-Return

2014-10-23 · If your machine has first-stage pressure set at maximum, or if you dont understand Delta P, set the first-stage pressure limit to the same pressure you use for pack-and-hold or second stage. Using second-stage pressure to test the non-return valve should insure against overpacking or damage to your runner or mold.
