Established in 1974, Nien Made (NM) is not only a listed company in Taiwan (Stock Code: 8464) but also the creator of its own brands, NORMAN® and VENETA®. We specialize in designing, manufacturing, and marketing a wide range of window covering products. With a long-term presence in multiple markets, including the U.S., Europe, the U.K., Japan, Australia, and New Zealand, we produce tens of millions of window coverings every year. With 11,300+ employees, our main production bases are located in mainland China, Cambodia, Mexico, and the U.S., with headquarters in Taichung, Taiwan.
NM offers practical and user-friendly "Stock window coverings," which are sold through ~2,200 Home Depot and ~5,200 Walmart stores. On the other hand, our affordably luxurious "Custom Window Coverings" are primarily distributed through our 11 regional business centers in North America, catering to thousands of local professional window décor retailers and designers.
Each year, NM manufactures millions of Custom window coverings, providing tailored solutions in various sizes, colors, materials, and options. We are highly vertically integrated, with tight control over raw materials and manufacturing. For instance, we produce 90+% of plastic components in-house to ensure product excellence. To maintain precision in our production processes, we follow strict lean production procedures and quality standards to minimize human error. Prior to shipping, our skilled craftsmen personally inspect each product for size, functionality, and appearance, adding final touches if needed. This rigorous craftsmanship ensures that only products passing our stringent quality control are shipped, exemplifying NM's unique pursuit of perfection.
Custom window coverings involve complex requirements — materials, sizes, light-blocking, and colors — often needing multiple accessories. Traditional production is prone to surplus or shortage of assembled components, creating unnecessary inventory of work-in-process or delays in later stages of manufacturing. Added to this are the challenges of multinational coordination before and after new product launches.
Through continuous on-site improvement (Kaizen) and adjustment, NM adopts a pull production system (Just-in-Time), producing only the quantities required and aligning output with team rhythm. To ensure optimal quality, we encourage autonomous Kaizen proposals — in 2024, we collected 3,000+ (avg. 2,858 over the past 5 years).
Thanks to lean production and an evolving culture, NM has improved quality, streamlined work, boosted energy efficiency, and softened the impact of rising wages and labor shortages. By applying the Toyota Production System (TPS) and lean methods, we efficiently deliver customized window coverings. Here are some examples of how this works in action.
