Tube end forming refers to a number of processes that require specialized tools, but no matter which process you are using the tube end forming machinery you use needs to be up to the task.
Tube end forming tends to fall into a couple of common categories that include reduction, expansion, beads, flare, and thickening. Each of these processes requires a different type of end forming tooling (you can learn more about end forming tooling here), but in general, each of these types of forming can be accomplished with the same machine, provided you have the right tooling.
The major difference in tube end forming machinery is in how the forming is accomplished. In general, tube end forming machinery falls into two categories, single and multi-strike forming machines. Each type of machine offers different benefits and limitations.
Single strike tube end forming machines tend to be less expensive than their multi-strike counterparts and offer faster cycle times and lower tooling costs. Multi-strike machines, on the other hand, offer users a greater degree of possible expansion or reduction. This means that multi-strike machines are more flexible than single strike machines, and they can also handle more complex shapes.
Which type of tube end forming machine is right for a given application often comes down to the applications specific requirements. For instance, a high-volume, simple end forming process that doesn’t require a great degree of expansion or reduction would probably benefit from the fast cycle times and straight forward end forming of a single strike end former.
For applications where the expansion or reduction that is needed is extreme, the end forming is complicated, or you needed to perform many types of end forming a multi-strike tube end forming machine might be a better option.
Your best bet is to gather your specifications and reach out directly to the supplier for help in determining which type of tube end forming machinery is right for your application.
