Complex Shapes

: The ability to form complex shapes accurately is one of the key advantages of stretch forming. Let’s delve into the reasons why stretch forming excels in this aspect:

  • Maintaining Dimensional Cross-Section Shape: Stretch forming ensures that the dimensional cross-section shape of the part is maintained throughout the forming process. Unlike other forming methods that may cause distortion or uneven deformation, stretch forming retains the original shape of the metal part. This is crucial, particularly in industries such as aerospace, where precise dimensional accuracy is essential for proper fit and functionality.
  • Minimal “Thin-Out”: Stretch forming minimizes “thin-out,” which refers to the reduction in material thickness during the forming process. This is achieved by carefully controlling the stretching forces applied to the material. By minimizing thin-out, stretch forming allows for the creation of complex shapes without compromising the structural integrity or strength of the part. This is particularly advantageous in industries that require intricate and lightweight metal parts, such as aerospace.
  • Maintaining Precise Tolerances: The stretch forming process enables the fabrication of metal parts with extremely precise tolerances. Precise tolerances refer to the allowable deviation from the desired measurements. Stretch forming companies can achieve high levels of accuracy in forming irregular and complex shapes, ensuring that the final parts meet the exact specifications required. This precision is crucial for industries that demand meticulous adherence to specifications, such as aerospace.
