20, May 2025, Tokyo, Japan - Victrex (UK, "Victrex"), a global leader in high-performance PEEK polymer solutions, has announced that one of its respected customers in Japan, Nichiei Corporation ("Nichiei"), an ultra-precision moulder of super engineering plastics, has received the Aisin Group Quality Excellence Award from Aisin Co. The award recognises Nichiei's superior manufacturing technology and quality control using the high-performance VICTREX PEEK polymer. The award-winning rod seal is an important component used in electronic stability control (ESC) devices that control skidding in vehicles.
Outstanding manufacturing performance that meets stringent quality requirements
Rod seals, measuring approximately 2 mm in diameter and 15 mm in length, are small components that provide precise hydraulic control in ESC equipment. In a mass production system with a monthly output of 2 million units, Nichiei has achieved an astounding quality record of zero defects for more than 100 million rod seals delivered to Aisin over the past six years, leading to this award.
The Aisin Group Quality Excellence Award is given to the supplier nominated by all four of the main Aisin Group companies. The award is based on a comprehensive evaluation of quality, delivery performance, processing technology and maintenance of manufacturing equipment over the past three years.
Advantages offered by VICTREX PEEK polymer
The use of VICTREX PEEK reduces component costs by approximately 30% compared to conventional carbon steel, while at the same time providing excellent durability with no deterioration in physical properties or dimensional changes even in a brake oil environment at 120°C.
Nichiei's President and Representative Director, Mr. Sugiura, commented as follows. 'Victrex's PEEK polymer has an excellent performance that meets our high-quality standards and stringent environmental conditions. The high reliability of this material has also made a significant contribution to our ability to achieve zero defects in rod seals, a component that requires extreme precision."
Victrex Japan's Head of Sales, Rentaro Higaki commented, 'We congratulate Nichiei on this prestigious award. We respect Nichiei's advanced technology and commitment to quality that maximises the outstanding performance of our PEEK polymers. Victrex will continue to support innovation in the automotive industry and further improve our products and services through strong partnerships with Nichiei and other Japanese and indeed global customers."
