TruHelix™ System – A New Addition to the CMF Line

Posted on

We at C Marshall Fabrication Machinery, Inc. are very excited to let you know that Advanced Spiral Technology has chosen us sell their patented TruHelix™ System.

The holder of the patent is Advanced Spiral Technology.  AST™ provides, not only the machine but, a complete software and hardware package for the accurate manufacture of helical screw flights.

There are two components to manufacturing a screw flights

  1. You need to accurately predict the size of the annular blank that, when formed, will produce a precise helix. The accuracy of the finished flight is directly determined by the accuracy of this prediction.
  2. You need to set the forming machine precisely to provide the appropriate AMOUNT OF TORSION to the annular blank to form the finished screw flight. The amount of torsion applied to the blank MUST INCLUDE an allowance to compensate for the spring back of the various materials being formed.

The AST™ system has software programs that accurately predict these two elements mentioned above.

As AST™ are able to predict the precise tooling and machine setup to produce the desired screw flight they are also able to determine the range and size of the tooling required to form the screw flights you require to manufacture.  In the AST™ “Professional” pack there are 42 sets of forming tools. It has been determined that this amount of tools is required to produce the full range of screw flights specified as the range of the machine.

If you are producing a varied amount of screw flights with different pitches and different diameters it will require a lot of different tools and once you start adding tools the price goes up as the tools are expensive.

If you are only doing a few specific screw Flights then let us put together a special package of tooling just for your requirements.

What is the TruHelix™  System?

AST™ TruHelix™  Flight Forming System revolutionizes flight design and manufacture.

TruHelix™  – Doesn’t use heavy pitch dependent forming dies. It uses a pack of lightweight forming plates that can produce flights of unprecedented quality regardless of the pitch, outside diameter and inside diameter. The same plates produce both left and right hand flights. Our patented systems use Young’s Modulos, Brinell Scale and other scientific data built into the software to ensure the accuracy of the forming process dependent on sizes and material s to be cut and formed.

TruHelix™ – the forming plates cost less to produce, wear and maintenance is minimal.

TruHelix™  – tools take up a fraction of the space required for conventional dies, can be changed by hand in a matter of minutes.

TruHelix™ – Operator training to reach full production capability is measured in days not years, producing top quality flights three to five times faster than old methods.

TruHelix™  – the Flight Blank Designer program will accurately calculate the perfect blank size based on inputting the finished size of your required flight, The Machine Configuration Tool shows the operator exactly how to set up the forming plates and what information to put into the SuperTyro™ Forming machine controls to produce consistent quality flights time after time, accuracy is assured.

TruHelix™ – the system forms (not deforms) the material to achieve a pure true helix shape, operator input is negligible. Fitting to centre tube and flight ends is improved and additional savings made by flight consistently fitting better requiring less labor time.

TruHelix™  – conforms to all OH&S requirements and meets CE (European Community) requirements for safety.

Flight Forming is now using 21st Century technology!
