Special Lap-Free Dies for Aerospace, Automotive & Other Critical Applications
Kadimi has developed a special solution called LF dies (lap-free dies) with special controlled thread-rolling technology, which yields to producing lap-free threads without compromising the Special Lap-Free Dies for Aerospace, Automotive & Other Critical Applications productivity.
The conventional thread rolling dies follow a standard penetration rate or the material flow into the dies, relative to the type of threads that are being formed. The blank during rolling will hardly be resisted with the crest being formed last in the dwell region of the die, typically forming a crest fold or minor lap.
