Nosinda's Continuous Anodized Aluminum Sheet Production Process Highlights Five Core Advantages
With the continuous improvement of aluminum performance requirements in high-end construction, new energy and electronic manufacturing industries, Shanghai Nosinda Metal Co., Ltd has become a benchmark enterprise in the field of domestic metal surface treatment by relying on its independently developed continuous anodized aluminum plate production process and driving product upgrades with technological innovation. Its production process has achieved breakthroughs in efficiency, quality, environmental protection and other aspects, providing more reliable solutions for downstream applications.
Core advantage 1: Fully automated continuous production, double improvement in efficiency and quality
Nosinda has introduced the internationally advanced continuous anodizing production line to achieve full automation control from aluminum coil unwinding, pretreatment, oxidation electrolysis, coloring to sealing. Compared with the traditional single-piece oxidation process, the production efficiency is increased by more than 300%, and the product consistency is excellent, with the color difference controlled at ΔE≤1.0 (industry standard ΔE≤2.0), meeting the stringent requirements of high-end customers for color uniformity.
Core advantage 2: Deep corrosion resistance, life extended by 50%
By optimizing the electrolyte formula and pulse oxidation technology, the density of the oxide film produced by Nosinda is 20% higher than that of the traditional process, the film thickness can reach 15-25μm (national standard ≥10μm), and the salt spray test is more than 2000 hours without corrosion, which is particularly suitable for coastal areas and chemical environments.
Core advantage 3: green process, zero pollution emission
The company implements the "dual carbon" goal, adopts chromium-free closed technology throughout the process, the wastewater recovery rate reaches 95% through the closed-loop treatment system, and the waste gas is purified by RTO incineration. The emission index is better than the GB 16297-2016 standard, and it has been awarded the title of "Shanghai Green Factory".
Core advantage 4: customized colors and surface effects
Relying on advanced electrolytic coloring and micro-arc oxidation technology, Nosinda can provide more than 100 RAL color options, and can achieve a variety of surface effects such as matte, glossy, and metal brushed, helping customers achieve personalized design.
Core advantage 5: Full-process technical support
From material selection recommendations to installation guidance, Nosinda is equipped with a professional team of engineers to provide "one-to-one" services. Its products have been successfully applied to landmark projects such as the curtain wall of the Shanghai Tower and the roof of the Tesla Super Factory, and the customer repurchase rate has exceeded 90% for three consecutive years.
Industry recognition:
Nosinda's continuous anodized aluminum plate has passed ISO 9001, SGS, EU CE and other certifications, and has become a recommended product by the China Nonferrous Metals Industry Association. In 2023, the company added 2 production lines, with an annual production capacity of more than 5 million square meters, further consolidating its market leading position.
Corporate Outlook:
In the future, we will focus on emerging fields such as new energy vehicle battery housings and photovoltaic brackets, and promote the deep combination of lightweight and weather resistance of aluminum oxide plates.
