Bending tubes are used in many different ways and can be bent either by doing so in house or by outsourcing the custom parts you need. There are also several types of bending, including compression bending, mandrel bending, and hydroform bending. Compression bending does not use any interior support, so flat spots and wrinkles are more likely to occur. Mandrel bending, on the other hand, supports the interior of the tubes, preventing collapse, and thus, produces wrinkle-free and smooth bends. Hydroform bending, then, uses fluid, instead, to support the interior of the tubes.
If you are trying to decide whether to produce the tubes in house with a tube bending machine or to outsource your needs to a tube bending manufacturer, you want to keep in mind your needs and capabilities. So, remember your budget and the amount that you need, then decide which would be more worthwhile for the needs of your business. If you decide to go with in house tube and pipe bending, look for multi-tasking machines to save money, think about purchasing refurbished or rebuilt bending equipment, and search for many quotes to find the best price for what you need. Business.com is a great resource for all of your bending tubes needs, as the site has plenty of informational links available to help you make the best decision for your company.
