With the improvement of living standard, people more and more high to the requirement of electric, magnetic relay is an important role in field application of automatic control, in recent years the increasingly fierce market competition, each relay enterprises are launched the latest version of differentiated products, especially the emergence of high-tech advanced technical performance index of the product, more to relay provides a broad stage.
At present, there are nearly 300 magnetic latching relay enterprises in China, most of which are producing low-cost magnetic latching relays, while only a few enterprises are expanding the production scale of high-end magnetic latching relays. China's magnetic latching relay production capacity is increasing, the pace of innovation is accelerating, the international competitiveness is also increasing.
The production of magnetic latching relays has a relatively intensive labor force. Developed countries transferred the general magnetic latching relays industry to China and other manufacturing countries with low labor cost earlier. Most of the early domestic enterprises were foreign-funded enterprises or their OEM enterprises, so the internationalization of the relay industry has always been relatively high.
However, in terms of market, the early automation level in China is generally low, and the demand for real intelligence and automation in major industries is weak. The market demand for magnetic latching relay products is also mainly export demand. Over the past 10 years, China's communications, automotive, industrial control, household appliances, such as the main magnetic stick relay consumption industry rapid development, driven by the needs of the domestic magnetic stick relay industry, and greatly reduce the export dependence characteristic of the magnetic hold relay, magnetic stick relay enterprise in our country's export share has fallen, from 50% a decade ago to around 30%.
Although China has been a real big country of magnetic latching relays, and has been the world's first exporter of relays for more than ten consecutive years, at the same time, China has maintained the import volume of magnetic latching relays equal to the export volume. The essence of its industry is that domestic export magnetic latching relays are still dominated by traditional products with low technical content and low added value. From the point of view of import and export unit price, the price difference ratio of import and export products has remained at about 80% in the past few years.
From the point of view of the client, the users in the field of construction and industry mainly purchase from the complete set of plate and cabinet factories; The construction of industrial projects mainly depends on the selection of magnetic latching relay products by the successful development of the system integrator project; Most users in the OEM market mainly purchase individual magnetic latching relay products, and some users in some industries, such as hoisting equipment, textile machinery and other industries, will purchase low-voltage cabinets from complete sets of plate and cabinet factories.
In recent years, the high value-added products of China's magnetic latching relay industry have been greatly improved, and in some fields have gradually replaced the imported products. For example, in the import and export trade, although the export quantity of China's magnetic latching relays has decreased, the export value has increased, indicating that the added value of export magnetic latching relays has increased, that is, the share of high added value magnetic latching relays in the export quantity has increased significantly.
The key competition of magnetic latching relay industry has developed from quantity competition to core basic R&D and manufacturing competition of new relays, key materials and special equipment. The value innovation point of magnetic latching relay R&D and manufacturing has been transferred to the core technology. Current and quite a period of time, the core of the basic industries and industry of our country magnetic stick relay control core technology are still being developed, the competitive advantage of developed countries is more obvious, the magnetic stick relay industry in our country's high-end products, the proportion of high value-added products, has been significantly improved, its technology, the quality has improved significantly, advantage gradually appear, passenger traffic growth drive operation density increases, the required magnetic stick relay gradually increase.
