Localized anxiety can influence forming success, and this boundaries how limited The within bend radius might be. Thermal processes like flame and laser slicing harden the sides and make tension concentrations.
The benefits of rotary bending incorporate producing ongoing, lengthy bends with consistent and exact Proportions. Rotary bending is well suited for producing profiles and designs with complex cross-sections. Having said that, rotary bending needs specialized devices and tooling.
