Processing on surface

Processing on surface

The swaging and flat-grinding process to improve the mechanical property. Auger with one spiral wire on the surface is available for Archimedes screw.



Auger

An additional filar twisted on top of a cable tube to create an auger screw-type component.


Swaging

Decreasing O.D. while maintaining inner lumen and stiffness by forging surface, can improve the elongation resistance.


Flat-grinding

Grinding on the surface in the whole length. It improves the flexibility of the metal tubes without decreasing the inner lumen.


Marking

We can put a mark to make clear the position of the metal tubing.
