TOKYO--(BUSINESS WIRE)--Jun 2, 2026--

NIPPON KINZOKU CO., LTD. (TOKYO: 5491) (Headquarters: Minato-ku, Tokyo) announces the launch of a sample supply system for its "Internally Polished Capillary Tubes."

This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260602111592/en/

These tubes feature significantly enhanced internal smoothness in ultra-small sizes, realized through the development of the company’s proprietary internal polishing technology.

We are currently proceeding with the design and construction of manufacturing equipment, aiming for mass production within fiscal year 2027.

Background: Rising Demand for "Ultra-Small Diameter x Ultra-Smooth Internal Surfaces"

We 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 ≤ 0.5μm, which have been highly evaluated across various industries.

In 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.

Key Features of "Internally Polished Capillary Tubes"

Leveraging our advanced precision processing technologies, this product delivers the following superior characteristics:

Southampton sticking by manager Eckert after Spygate controversy

SOUTHAMPTON, England (AP) — Southampton manager Tonda Eckert will keep his job despite helping to orchestrate the Spygate controversy that cost the club a chance of promotion to the Premier League, owner Dragan Šolak said on Tuesday.

Southampton was expelled from the second-tier Championship playoffs last month after admitting to repeatedly spying on opponents' training sessions and also given a four-point deduction for next season.

In its written reasons published on Monday, an arbitration panel laid bare the influence of Eckert in the scandal, saying it was “a contrived and determined plan from top down to gain a competitive advantage” and analysts who carried out the unauthorized filming “felt pressurised to do the observations that Mr. Eckert and the senior coaches wished them to do.”

However, Šolak said in a video message to fans published on Tuesday that the club believes Eckert “is the man to take us forward.”

“As a board, we are fully behind him,” the Serbian owner said, “and together we only have one objective — we want promotion back to (the) Premier League.”

In an interview with the BBC, Šolak said Eckert "deserves a second chance and I would give it to him.”

Southampton qualified for the playoff final — after beating Middlesbrough, one of the clubs it spied on — before getting expelled. That deprived the Saints of the chance of promotion to the top flight and a guaranteed windfall of at least $270 million in future earnings.
