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 the continuous great self-improvement of drawing process.
※ By making plug and dies by itself, Nippon Tokushukan can promptly and flexibly satisfy customers’ requested size.
Plug-Drawing Technology
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 a method of controlling inner dimension and preventing roughness of inner surface and as a consequence, there happens size spec non-satisfaction and inner roughness & roundness deterioration.Nippon Tokushukan’s plug drawing with fine plug& dies can achieve its controlling and preventing.Nippon Tokushukan has fabricated dies and plugs in the meticulous management since 1965 and now creates and utilizes even the floating plug for ID:Φ0.08mm. It is owing to endless thorough management of making plug and dies on Nippon Tokushkan’s own since 1965.By creating dies and plugs by itself, Nippon Tokushukan can promptly deliver all requested size of super-micro capillary tubes.
