Drawing Technology#01

Nippon Tokushukan has established a tech of manufacturing super-micro capillary tubes with fine dimension, good roundness and smooth inner roughness through thorough continuous improvement of drawing process.We make it possible to manufacture
OD:Φ0.05mm x ID:Φ0.03mm
at present.
※ By making plug and dice by itself, Nippon Tokushukan can promptly and flexibly satisfy customers’ requested size.

About Plug-Drawing Tech

The below photos show the difference of inner roughness between plug drawing and non-plug drawing.
The left photo shows the inner roughness in the conditions of plug drawing Nippon Tokushukan has implemented since 1960.The right photo shows the inner roughness in the conditions of non-plug drawing generally utilized for manufacturing capillary tubes until now.Non-plug drawing is not means of controlling inner dimension and preventing roughness of inner surface and as a consequence, there often happens size specs non-satisfying and deterioration of inner roughness & roundness.Nippon Tokushukan’s plug drawing with fine plug& dice makes it possible for controlling and preventing.Nippon Tokushukan has fabricated and utilized floating plug for ID:Φ0.08mm controlling. It is owing to endless thorough management of making plug and dice on Nippon Tokushkan’s own since 1965.By making plug and dice by itself, Nippon Tokushukan can promptly and flexibly satisfy customers’ requested size.
