NIPPON KINZOKU has Commercialized Small-Diameter Tubes with “Inner Surface Precision”

Achieved commercialization of inner diameter ?0.5mm and surface roughness Ra0.5?m or less

TOKYO–(BUSINESS WIRE)–NIPPON KINZOKU CO.,LTD. (TOKYO: 5491) (Headquarters: Minato-ku, Tokyo) announced it has commercialized a “high-precision inner surface” small-diameter pipe (fine pipe) with an inner diameter of ?0.5mm.

High-precision inner pipes are manufactured by inserting a dice into the inner diameter and drawing. If the inner diameter is smaller, even if the dice is inserted, the thickness change during drawing and the behavior of the dice inside the pipe will not be stable, making it difficult to increase the precision of the inner surface. This time, we have established a new manufacturing method that produces a good inner surface even with an inner diameter of 0.5 mm. As a result, customers who require small-diameter, thick-walled pipes with high-precision inner surfaces can reduce the need for inner surface treatments such as polishing or coating, contributing to both cost reduction and resource conservation.

We have received inquiries from manufacturers of measuring instruments and medical devices that require precise and smooth flow control for small-diameter tubes with high-precision inner surfaces, and we are providing samples and considering mass production.
