Press braking and roll forming are both types of metal bending and forming, but besides the fact that they both fall under the same basic process type, they have little else in common. Both processes are important, and both have distinct advantages and disadvantages, and their appropriate use depends entirely on the end product being fabricated. This week, we’ll take a look at closer look at press braking, and you can come back next week to see how it compares to roll forming.
Press Braking Advantages
Press braking is one of the most common forms of metal bending because it is generally both cost-effective and efficient compared to the other available options. Press brakes also have a faster, easier setup process, which contributes to its comparatively low cost. In general, it’s considered the least expensive of the bending processes and is incredibly useful and integral facet of most full-service metal fabrication companies.
Press Braking Disadvantages
Although we do often utilize press brakes for fabrication, there are times when it’s simply not the right process for a given job. Press braking is best for small-to-medium part volumes, so for fabricators that specialize in very large production runs of a single product, it is usually not a great choice. The exception to this rule is when press braking is automated via robots, in which case, even very large production runs are possible. One reason why EVS uses press braking quite frequently is that we often work with clients who require short runs, or even prototypes of various products, in what’s overall considered a high-mix, low-volume production environment. Therefore, press braking is usually our go-to bending process.
Press brakes also cannot make bends for parts longer than a typical bed length (at EVS, that would be 10′, but there are beds as long as 12′). Longer part lengths would generally go through the roll forming or stamping process instead. Exceptionally tight tolerances, i.e. those of less than +/-.005, are generally not ideal candidates for press braking. Finally, metal items that have undergone the press braking process will not look as immediately “finished” as parts that have been bent in other ways, such as via roll forming. This means the product may require a secondary finishing process such as painting, powder coating or polishing if it is to be sold as a stand-alone item, instead of fabricated as a part to be later integrated into a larger product.
Press Braking: A Fabrication Workhorse
With only a handful of exceptions, modern press braking is a fabricator’s best friend. In fact, it’s very often the best bending option in low-volume, high-mix environments like that found at EVS Metal.
