<\/a><\/a>\nThese tubes feature significantly enhanced internal smoothness in ultra-small sizes, realized through the development of the company\u2019s proprietary internal polishing technology.<\/p>
\nWe are currently proceeding with the design and construction of manufacturing equipment, aiming for mass production within fiscal year 2027.<\/p>
\nBackground: Rising Demand for \"Ultra-Small Diameter x Ultra-Smooth Internal Surfaces\"<\/b><\/p>
\nWe have previously developed high-precision, small-diameter tubes made of austenitic stainless steel with an internal diameter (ID) of 0.50mm and internal surface roughness of \u2264 0.5\u03bcm, which have been highly evaluated across various industries.<\/p>
\nIn recent years, the advancing performance of analytical, medical, and biotechnological equipment has driven a rapid surge in demand for capillary tubes with even smaller diameters and smoother internal surfaces. To achieve a level of internal roughness in the 0.30mm ID class that was previously unattainable through conventional manufacturing methods, we have established our proprietary internal polishing technology.<\/p>
\nKey Features of \"Internally Polished Capillary Tubes\"<\/b><\/p>
\nLeveraging our advanced precision processing technologies, this product delivers the following superior characteristics:<\/p>
- \n
- \nUnmatched Internal Smoothness:<\/b> Dramatically reduced internal surface roughness from the conventional Ra \u2264 0.5\u03bcm to Ra \u2264 0.2\u03bcm.<\/li>\n
- \nHigh Dimensional Precision:<\/b> Achieves a tight internal diameter (ID) tolerance of \u00b10.03mm across ultra-small sizes ranging from 0.30 to 0.70mm.<\/li>\n
- \nExcellent Corrosion Resistance:<\/b> Constructed from high-grade austenitic stainless steel, these tubes are ideal not only for analytical instruments but also for diverse applications including medical\/biotech equipment, semiconductors, and high-purity gas supply systems.<\/li>\n<\/ol>
