Engineering Bulletin: Use Easy Metal Flow Tooth Form to Eliminate Flaking

Learn how CJWinter's Easy Metal Flow Tooth Form eliminates flakes during the thread rolling process

Different materials have different forming characteristics during the thread rolling process. High sulfur, for example, can create flakes and slivers, thereby hindering the thread finish during cold forming.

The solution: Easy Metal Flow Tooth forms — a special form that concentrates forces at the root of the thread form, which helps plow material more efficiently during the cold form process. Ultimately, the increased and concentrated force minimizes, and in most cases eliminates, flakes from being produced when rolling brass, high sulfur, and other materials prone to flaking.
