1. Development status of the international electromagnetic wire industry
In 1831, the British physicist Faraday discovered the phenomenon of electromagnetic induction, which made the transformation of magnetism and electricity a reality. Since then, equipment such as generators, motors and transformers have been widely used, and human civilization has entered the "electric age". Since then, as the main components of various motors and electrical appliances, the magnet wire has been widely used, and the magnet wire industry has been born and gradually developed.
The change and rapid development of the magnet wire industry began in the second industrial revolution, during which catalytic combustion technology and mold painting technology were invented. The variety, production scale, and manufacturing technology have all been improved, and the first generation of well-known leading companies of magnet wire, such as Essex in the United States, Phelps Dodge, and Alcatel in France, have been born. At the beginning of the 20th century, GM of the United States continued to develop new insulating materials, and successively made oil-based enameled wires, acetal enameled wires, polyester enameled wires, etc., which enriched the types of magnet wires and made magnet wires more widely applicable.
Since the early 1960s, glass enameled wire, silicone enameled wire developed in Japan, and polyurethane enameled wire developed in Germany have further expanded the category of single-layer magnet wire. Since then, Phelps Dodge and DuPont have successively made composite enameled wires, which greatly improved the performance of magnet wires, and gradually formed three traditional production bases in North America, Japan and Western Europe.
Since the beginning of the 21st century, the world economic structure has changed. As the downstream customers of magnet wire have moved their production bases to Asia, central and southern America and other regions, the manufacturing base of magnet wire products has been transferred to China, India, Southeast Asia, and Central America. South and Eastern Europe and other places, Asia has become the world's most important magnet wire production area. Due to the long history of magnet wire production in developed countries and the mature market, their magnet wire manufacturers have entered different development directions of scale or specialization. For example, Essex in the United States is one of the largest magnet wire/winding wire manufacturers in the world. It has more than ten production bases around the world; Germany's Elektrisola focuses on the research and development and production of ultra-fine wires and is the world's largest manufacturer of ultra-fine magnet wires; Japan's Sumitomo Electric is famous for its high and stable quality and has 7 production bases around the world , occupying about 10% of the global market share.
2. Development history of my country's electromagnetic wire industry
Compared with developed countries in Europe and the United States, my country's magnet wire industry started late, but it has grown rapidly. In 2010, the output of magnet wire industry has surpassed traditional production bases such as the United States and Japan, becoming the world's largest magnet wire producer and consumer country. The current annual production accounts for about 50% of the global total. The development of my country's electromagnetic wire industry has mainly gone through the following three stages:
(1) Germination stage (before 1980)
Before 1980, my country's magnet wire industry was mainly based on a self-reliant development path led by state-owned enterprises. Enterprises at this stage are mainly characterized by small production scale, relatively backward technology, single product variety, poor quality, and high production costs. By 1980, there were more than 200 magnet wire manufacturers in my country. Although the number of enterprises was large, they were generally small in scale. The total annual output was only 50,000 tons, accounting for 4.55% of the global annual output. Due to the single product variety, my country's demand for magnet wire is largely dependent on imports. Most of the magnet wires produced by the enterprise are sold by the electromechanical equipment companies in various places, and the production and sales motivation is greatly inhibited.
(2) Growth stage (1980-2005)
Since the early 1980s, my country has entered the market economy and implemented the opening-up policy, and domestic magnet wire companies have begun to introduce production lines from Austria, Japan, Italy and Taiwan, my country. The product structure, technical level and production capacity of China's magnet wire industry have rapidly improved . As the country formulated a series of policies to encourage technology research and development, the household appliance industry took the lead in responding, and high-tech products such as green refrigerators, inverter energy-saving air conditioners, and large-screen high-definition color TVs emerged one after another, bringing new developments to the production of magnet wires. Opportunities, the technology began to develop in the direction of "environmental protection, energy saving, frequency conversion", and the production scale was expanded to more than 10,000 tons. New market-oriented state-owned and non-state-owned enterprises have grown rapidly, product production is based on market demand preferences, and customer satisfaction has greatly improved. Relying on the introduction and accumulation of technology, new state-owned enterprises have formed some well-known enterprises in the industry. Non-state-owned enterprises occupy a place in the market with high-quality sales services and fast market response speed. At this stage, due to the different companies' ability to grasp market opportunities and the speed and rhythm of product development, the development of the industry is extremely uneven. There are fewer than 10 large-scale enterprises, and the general production volume ranges from 2,000 tons to 10,000 tons.
(3) Rapid development stage (2005 to present)
With China's entry into the WTO, the globalized market economy has injected a large amount of capital and technology into my country's magnet wire industry, making the production capacity of my country's magnet wire manufacturers expand rapidly. During this period, my country's economy has grown rapidly, and the downstream industries of magnet wire, such as automotive motors, power tools, industrial motors, household appliances, etc., have rapidly expanded the market scale. The demand for magnet wire is strong, and the production capacity of some enterprises in the industry has expanded to more than 10,000 tons. For non-state-owned enterprises, capital restrictions are gradually reduced, and production technology, R&D strength and product quality have improved significantly. The open market makes technology integration more frequent, and the matching of my country's electromagnetic wire products with the products of foreign downstream enterprises is becoming more and more mature.
With the rapid development of my country's new energy vehicles, electric power industry, electronic information and other industries, the scale of the electromagnetic wire industry has expanded rapidly. Domestic electromagnetic wire manufacturers with scale advantages and financial strength have made great progress in technology research and development and product development. The gap between technology and product structure and developed countries is gradually narrowing.
