True Form Helices

Helix Flight's forming machines are globally recognised with a positive reputation for the consistent production of True Form helices. This is a vital factor in ensuring that the manufactured helices are precision-made, and uniform to specifications so that they fit-up snugly, and with ease onto the shaft or pipe. A factor that is equally important is when joining the helices together edge-to-edge, in a continuous running length, this is where it is critical to have a perfect alignment of helices.

Helix Flight's machines form helices that are manufactured to exceptionally high standards of quality, and are also recognised as being highly-accurate to any given specification. Therefore, this removes the inconvenience and extra time spent when having to re-work the helix, with the extra need for tabs being pre-cut into the blank... This adds up to an additional need for more labour costs to cover the extra time taken for the preparation, grinding and polishing.

Of course, this has a knock-on effect to client relations, as the additional labour charges and subsequent increase in costs are handed-on to the client for them to absorb. Then; even worse, when the Helices are compared side-by-side, it becomes clear and evident that although the client has ended-up paying considerably more, the product is noticeably of a far inferior quality. An awkward situation (at best) avoided with the use of Helix Flight's forming machines.

The main characteristics of a True Form Helix are...

The Helix flange is positioned at 90 degrees to the shaft,
and the Helices internal edge is parallel to the shaft.
Forming a consistently uniform, perfect Pitch angle.

The multiple benefits of producing True Form helices...

An accurate fit-up to the shaft gives a much quicker, efficient handling performance. Helix Flight's manufactured helices click directly into position on the shaft in a tight and easy manner and without the need for any secondary processes, such as grinding or cutting being necessary.

The uniformity of the weld procedure, to maintain consistency, is critical to the robotic welding process and this is also important in manual welding operations too.

Flush edge-to-edge joins make a considerable difference to production turn-around performance too. If the helices internal edge is not parallel to the shaft it results in significant variations to the size and shape of the weld root. This issue produces inconsistency with the characteristics of the material being formed, creates weaknesses in the jointing, and unavoidably, a noticeably poor quality weld.
