Mandrel Bend is a high-precision metal tube bending process with the following key features:
Technical principle:
Insert a support rod (Mandrel rod) inside the pipe
Maintain uniform pipe inner diameter shape and wall thickness during bending
Prevent pipe deformation, wrinkles and uneven wall thickness
Core advantages:
- Geometric accuracy
Maintain perfect roundness of pipe inner diameter
Precise and controllable bending radius
Constant wall thickness
- Performance characteristics
Reduce air flow resistance
Maintain pipe structural integrity
Improve exhaust system flow efficiency
- Application areas
Automotive exhaust system
Aerospace engineering
Industrial pipelines
Racing car modification
Precision machinery manufacturing
Comparison with traditional pipe bending:
Traditional pipe bending: easy to deform, uneven wall thickness
Mandrel Bend: precise, uniform, excellent performance
Process flow:
Select suitable pipe
Built-in support Mandrel rod
Precise hydraulic or mechanical bending
Control bending angle and radius
Final inspection and quality verification
