Tube Bending: 5 Tips On Designing Cost Effective Tube Bends

Planning cost effective bends for your tube bending jobs can be more included then it may look. The cost in making a common pipe or tube bend is immediately afflicted by the quantity of work force,, labor force and tooling had to produce your parts. So as to have the most cost efficient tube bends, the following are some key factors to consider.

1. ) In traditional mandrel pipe and pipe bending, a bend pass away that is built for a specific radius is required to build a fold. These bend dies can range in cost from $2, 000 up to $10, 000 depending on your pipe and conduit size and the radius size. For high quantity jobs the price tag on the fold die might not exactly be a concern, but for small goes it can be critical. It is possible to avoid these large tooling costs in cases where there is overall flexibility in the radius. Consulting with your conduit bending house to see which radii bend passes away they own and then choosing one of these radii to design your bend helps you to save on tooling costs and lead time.

2. ) In addition to choosing a die that already exists picking out a radii that is more than 1-1/2 times the tube size will cause an inexpensive bent part because middle line radii tighter than 1-1/2 times the pipe diameter will be more labor intensive and may have increased part cost. Intended for instance a 4″ U. D. tube bent on a 6″ centerline radius (C. L. R. ), which is 1-1/2 times the 4″ diameter, is less labor intensive than 4″ O. D. firmer bends such as ones that are between a 4″ and 6″ C. L. R.

3. ) Typical pipe and pipe bending processes with parts which may have more than one bend demand a straight span between the bends. Regular tooling can accommodate parts that allow a distance between bends of at least 3 times the tube diameter. Parts which may have a distance less than three times the dimension are possible to produce, but may require special tooling which in switch increases tooling charges. A great exception to this regulation exists with a different bending technology, the Nissin tube bender. This technology pertains to 1-1/4″ O. M. and smaller bent on a radius that is 3 times the size.

4. ) When making a part there can be a tendency undamaging with dimensional tolerances when specifying your needs, but for cost efficiency it best to you can keep them only as tight as required. Specifying tighter tolerances is likely to make the project more time consuming and possibly increase your costs. Again, consulting with your bending house to see what bending tolerances can be held while meeting your requirements less unnecessarily increasing your costs will be beneficial to the design and making phases of your curled tube project(s).

5. ) Many customers are likely to use a thinner wall for their projects to reduce material costs. However, slimmer wall tubing may require more labor to bend over, (as in a few instance it might not exactly have the ability to hold the roundness of the pipe as it is curved and cause ripples or wrinkling in the bend). Sometimes the additional work force,, labor force costs outweigh the materials savings therefore it may or may well not be good for use a thinner and more fit wall material.
