Hollow Stabilizer Bar Three-Layer Attachment Folding

The attachment portion transitions from a simple flattened shape to a three-dimensional multi-layered structure through folding. The pipe material is folded back to form multiple layers (first, second, and third layers) with overlapping surfaces, creating vertical dimensionality that increases attachment strength without proportionally increasing the horizontal width dimension.

The pipe material is folded back to form multiple layers and overlapping surfaces before trimming is performed. This preliminary folding action creates a structured multi-layer configuration where the overlapping surfaces maintain material continuity. When trimming is subsequently applied to reduce width, the folded structure ensures that the pipe material remains continuous through the overlapping regions, preventing separation.

The pipe material is folded to form a multi-layered structure with overlapping surfaces before any trimming or bending operations. This preliminary folding establishes a configuration where the material continuity is preserved through the overlapping regions. Subsequent trimming and bending operations can then be performed without causing positional offset of through holes, as the folded structure maintains structural integrity and alignment throughout the manufacturing process.

Instead of simply reducing width by cutting material, the pipe is folded to create a multi-layered structure that utilizes vertical dimensionality. The overlapping surfaces distribute mechanical loads across multiple layers, maintaining or even enhancing mechanical strength while achieving a more compact horizontal footprint. The folded structure provides structural reinforcement that compensates for any material removed during trimming.
