Nakano Sangyo specialises in the development, manufacture and sale of legwear, primarily pantyhose, alongside OEM and ODM production for the apparel industry. Its proprietary products, which prioritise comfort alongside functionality and design, enjoy widespread popularity.
Moreover, by applying these manufacturing technologies and equipment, the company also produces and sells industrial filter materials for industrial filtration units and strainer pipes. The stocking material, characterised by its elasticity and fine mesh, is well-suited for sectors demanding high functionality, such as medical, automotive, and food hygiene. This has grown into the company's second pillar of business.
The company's greatest strength lies in its production system, which handles every stage in-house from knitting and dyeing to sewing and finishing. It has introduced the latest computer-controlled knitting machines and sewing robots, while also conducting thorough quality checks at every stage without fail. Under this rigorous quality management, it responds flexibly and swiftly to diverse needs.
Furthermore, the elasticity and intricate knitting techniques honed in stocking production, which underpin their high quality, have been applied and developed for industrial filter manufacturing. Their industrial filters combine cost-effectiveness, environmental consideration, simplicity, versatility, and customisability. Consequently, their adoption is expanding in sectors with high quality requirements, such as medical, automotive, and food hygiene.
Combining years of development experience with a commitment to technological innovation, the company continues to create new value, exemplified by its patented “bag-shaped filter”.
Their legwear manufacturing division excels in product development and planning capabilities. Beyond their commitment to the comfort of pantyhose and legwear, they introduce unique products featuring functionality and design, such as using natural materials, incorporating antibacterial and anti-static properties, and applying print finishes.
Furthermore, they operate their own factory brand, RONMON, embodying their philosophy: ‘Precisely because it is something worn daily, we wish to deliver uncompromising quality.’ They also manage an online B2C business.
The company's industrial filter business embodies the pinnacle of its technological expertise. Its industrial filtration filters are developed and manufactured with a core focus on filtering particles at the 10μm level. It is currently advancing further technological innovation, including developing filters capable of removing particles down to 3μm.
Furthermore, the company delivers customised solutions tailored to each customer, providing pre-installation samples for testing prior to delivery. This approach boasts an order conversion rate exceeding 90%, demonstrating the company's strong product development capabilities, uncompromising quality, and the resulting high levels of customer satisfaction.
