Software diagnoses runner imbalancesSoftware diagnoses runner imbalances

Offering molders a five-step diagnostic tool to commission multicavity molds, a new software program finds and solves filling imbalances that can hamper initial part runs. The 5-Step Process from Beaumont Technologies covers 19 base layouts for multiple cavity tools, including four-cavity inline, eight-cavity X-pattern, and 16-, 32-, and 64-cavity H-pattern tool designs.

The software diagnoses factors ranging from shear-induced flow imbalances, to dimensional variation in the mold, cooling affects, and hot runner systems. The program works by using molded sample parts (which are collected, labeled, and weighed) to identify steel variations in the mold according to part weights. These data are used to determine the percent variation caused by shear. Charts are created automatically to allow moldmakers and molders to predict were imbalances in runner systems might occur before cutting steel or shooting any parts. Windows98 or higher is compatible, but WindowsXP is recommended, as is 256 MB RAM, a 500-MHz processor, and 75 MB of disk space if MS Access XP or higher is running, and 150 MB if it isn't.
