Bend / Rebend Testing Services
Professional bend and rebend testing services to evaluate the ductility, flexibility and structural integrity of metallic materials in accordance with national and international testing standards.
Reliable Bend & Rebend Testing for Material Performance
Bend and rebend testing is an important mechanical testing method used to evaluate the ductility, flexibility and structural behaviour of metallic materials such as sheets, plates, strips, bars and wires.
During the test, the specimen is bent over a specified diameter using standardized testing procedures to determine whether the material can withstand deformation without cracking or failure.
Om Metalab performs bend and rebend testing using calibrated equipment and follows internationally recognized standards such as ASTM, IS, BS and ISO to ensure reliable and repeatable results.
Why Bend Testing Is Performed
Bend testing helps determine whether a material possesses the required ductility and flexibility to perform safely under actual service conditions.
Ductility Evaluation
Determines the ability of a material to deform without cracking or breaking during bending.
Flexibility Assessment
Evaluates how well the material withstands bending under specified loading conditions.
Weld Quality Verification
Used to assess welded joints and verify their integrity after fabrication processes.
Quality Compliance
Confirms that materials comply with customer specifications and applicable testing standards.
Standard Bending Techniques
Different bending methods are selected based on material type, product geometry and applicable testing standards.
- Three Point Bend Test
- Four Point Bend Test
- Mandrel Bend Test
- Reverse Bend Test
- Guided Bend Test
- Wrap Around Bend Test
Evaluation Criteria
During bend and rebend testing, our engineers carefully examine material behaviour to verify compliance with applicable testing standards and customer specifications.
Angle of Deflection
Measures the bending angle achieved by the specimen under specified testing conditions.
Cracks & Fractures
Examines the specimen surface for visible cracks, fractures or other signs of material failure.
Recovery Behaviour
Evaluates the ability of the material to recover its original shape after bending wherever applicable.
Material Integrity
Confirms the structural integrity and suitability of the material for its intended engineering application.
Standards We Follow
Bend and rebend testing is performed in accordance with recognized national and international testing standards to ensure reliable, accurate and compliant results.
