Feed bending (FR bending) – Overview materials and sizes

  • As the part is processed by feed bending (FR bending), stamp marks will be visible on the bent part.
    Details can be found under Bending Specifications for details.

  • If you require bending processing without stamp marks, please enter this in the additional information in the 3D viewer and request a manual quotation.

    • *1 The thickness tolerance is ±10% (reference value).
    •  
    • *2 The maximum and minimum dimensional values are limited by the
      shape of the bend.
    •  
    • *3 Select a paint color from the table (Appendix Table).
    •  
    • *4 The maximum length and width dimensions (Appendix Table) may vary depending on the surface treatment.
  •  
    • *5 The machining surface will not be plated as it is a pre-treatment material.
    •  
    • *6 Protective sheets (one-side only) affixed.
    •  
  • *7 See figure below for hole diameter and hole pitch standards.
  • However, the hole pitch orientation can be set to any value.
