Flash Free Molding, Part 2
I hope you found the first article on flash free molding interesting. [Read Flash Free Molding Part 1.] I covered cavity pressure versus clamp pressure and will talk tool deflection in this article. Tool design and construction can be a contributor to flash issues. But, if you read the first article and the three conditions are met, flash is not possible. An inadequate tool design can contribute to flash by allowing deflection in line with clamp force and perpendicular to clamp force. Also, on the construction side, improper spotting, timing of components, and fitting of components can be contributors to flash. (more…)
