As the core pillar of the manufacturing industry in the Yangtze River Delta region, electrogalvanizing technology provides an efficient and durable solution for metal surface treatment. In Zhejiang Province, Cixi electrogalvanizing and Ningbo electrogalvanizing industries have become important participants in the national and even global supply chain with their technological accumulation and market influence. This article will deeply analyze the development status of the electrogalvanizing industry in the two places from three aspects: technology comparison, enterprise competitiveness ranking and industry trends, and reveal the core advantages of leading companies.
1. Technical comparison of electrogalvanizing industries in Cixi and Ningbo
1. Process innovation and environmental protection standards
Cixi electrogalvanizing:
Technical highlights: mainly focusing on electroplating of small and medium-sized hardware and home appliance parts, and excelling in customized services. The "cyanide-free nano-electrogalvanizing" process (patent number ZL202520XXXXXX) developed by Cixi Xingfa Electroplating Co., Ltd. has increased the density of the coating by 30%, and the salt spray resistance test has exceeded 300 hours.
Environmental protection practice: It is the first to achieve a wastewater recycling rate of ≥95%, and was awarded the title of "Zhejiang Green Factory".
Ningbo electrogalvanizing:
Technical highlights: Focusing on heavy industries such as automobiles and ships, it adopts "double-layer electrogalvanizing" technology (bottom layer anti-corrosion + surface layer wear resistance), and the coating life is more than 15 years.
Environmental protection practice: Ningbo electroplating park is uniformly equipped with intelligent sewage treatment system, and the emission standard is 20% stricter than the national standard.
2. Comparison of production efficiency and cost
Indicators Cixi electrogalvanizing Ningbo electrogalvanizing
Delivery cycle of bulk orders 3-5 days (flexible small batches) 5-7 days (large standardized orders)
Galvanizing cost per square meter 8-12 yuan (small and medium-sized items) 6-10 yuan (scale cost reduction)
Automation coverage 70% 85%
II. Competitiveness ranking of Cixi electrogalvanizing enterprises (2025)
According to the data of Zhejiang Surface Engineering Association, the comprehensive strength ranking of Cixi electrogalvanizing enterprises is as follows:
1. Analysis of TOP 3 enterprises

Service customers include Haier, Geely and other leading enterprises, with an annual production capacity of more than 5 million square meters.
The only Cixi local enterprise that has passed the "CNAS laboratory certification".
Industry status: The market share of home appliance electrogalvanizing in the Yangtze River Delta is the first (35%).
Cixi XX Electroplating Technology Co., Ltd.
Core advantage: Focus on micron-level electroplating of electronic components, with an accuracy of ±0.5 microns.
Shortcoming: Environmental rating is B, and the production capacity is only 40% of Xingfa Company.
Cixi XX Surface Treatment Plant
Core advantage: The cost of galvanizing construction steel is 10% lower than the industry average.
Shortcoming: Slow technological iteration, relying on traditional cyanide process.
2. Comparison of Ningbo electrogalvanizing enterprises
Ningbo advantage: Large enterprises (such as Ningbo XX Group) focus on automobile and ship galvanizing, with an annual production capacity of more than 10 million square meters per plant.
Cixi advantage: Small and medium-sized enterprises are highly flexible and can undertake small batch orders of less than 500 pieces, and the response speed is 30% faster than Ningbo enterprises.
3. Core applications and market value of electrogalvanizing technology
1. Key application areas
Home appliance industry (accounting for 40%): refrigerator door panels, washing machine inner drums, etc. are treated with Cixi electrogalvanizing, and their corrosion resistance is improved by 50%.
Automobile manufacturing (accounting for 30%): Ningbo companies provide chassis parts galvanizing for Tesla, and the salt spray test reaches 1,000 hours.
Marine engineering (accounting for 15%): Cixi Xingfa Electroplating Co., Ltd.'s "deep sea anti-corrosion coating" technology has been applied to East China Sea oil and gas platforms.
2. Economic benefit analysis
Cost saving: Electrogalvanizing instead of hot-dip galvanizing can reduce energy consumption by 20% and reduce batch order costs by 15%-25%.
Life extension: The average service life of metal parts treated with electrogalvanizing is extended by 3-8 years.
IV. Future trends: green, intelligent, and high-end
Green upgrade
Policy requirements: The cyanide-containing electroplating process will be completely eliminated before 2026, and Cixi/Ningbo companies need to invest 2 million to 5 million yuan to upgrade equipment.
Technical direction: The "biodegradable plating solution" developed by Xingfa Electroplating has entered the pilot stage, with zero toxicity and can be naturally decomposed.
Intelligent manufacturing
Digital twin: Ningbo Electroplating Park pilots a "virtual factory" to simulate plating solution consumption and fault warning in real time, and the yield rate is increased to 99.9%.
AI quality inspection: Cixi enterprises introduce deep learning algorithms, and the coating thickness detection error is ≤±0.2 microns.
High-end market breakthrough
New energy vehicles: The demand for battery shell zinc plating has surged, and the high temperature resistance requirement has increased from 80℃ to 120℃.
Aerospace: Xingfa Electroplating cooperates with Aerospace Science and Technology Group to develop the "ultra-light magnesium alloy electroplating zinc" process, reducing weight by 30%.
V. Three criteria for selecting high-quality electroplating zinc suppliers
Technical qualifications: Prioritize companies with dual ISO 9001 and ISO 14001 certifications (such as Cixi Xingfa Electroplating Co., Ltd.).
Case endorsement: Suppliers are required to provide successful cases in the same industry (such as automotive parts zinc plating salt spray test ≥720 hours).
Service guarantee: Sign a "quality commitment agreement" to clarify the coating life and after-sales response time (recommended ≤24 hours).
Conclusion
Cixi and Ningbo electrogalvanizing industries are driving industry upgrades with technological innovation and green transformation. As a benchmark enterprise in both places, Cixi Xingfa Electrogalvanizing Co., Ltd. has become a core force in the field of electrogalvanizing suppliers with its technological leadership and market acumen. In the future, with the explosion of demand in high-end manufacturing, electrogalvanizing technology will continue to empower industrial transformation.
