Technology of Tube Drawing

[ Technology of Tube Drawing ]
With our own drawing Technology we'd established for decades, we can supply micro precision tube with high accuracy in dimensions, roundness and smooth inner surface.
At present, we can manufacture our smallest tube
"OD 0.05mm x ID 0.03mm"

We manufacture the toolings (die and plug) for tube drawing by ourselves, so we can manufacture various sizes rapidly and flexibly.
[ Comparison between Plug Drawing and Sunk Drawing ]
The roughness of inner surface is quite different between Plug Drawing and Sunk Drawing. Plug Drawing realizes to manufacture accurate fine precision tube
