TruHelix™ – Flight Forming Technology Lifts the cloak on an old ‘Black Art’
Until Advanced Spiral Technology's TruHelix Flight Forming System helical screw flights were primarily formed by "pitch" dependent dies in various forming machines. The accuracy and consistency of the helical form was largely a function of the die pitches, the experience of the press operator and the accuracy of the cut annulus from which the helix was formed.
