Break the decade-long technological monopoly !Tianjin Cinmea has obtained the core patent for helical compression springs.

Recently, Tianjin Cinmea Technology Co., Ltd. (hereinafter referred to as "Cinmea Technology") announced major good news: its independently developed technology for a helical compression spring has been successfully granted a national patent.

The successful grant of this patent not only marks a major breakthrough in core technologies by Cinmea Technology in the spring manufacturing sector, but also breaks the more than decade-long technological blockade imposed by foreign enterprises in this field, fills domestic technological gaps, and provides strong impetus for the independent and controllable development of China’s high-end spring manufacturing industry.

As a fundamental core component widely used in machinery manufacturing, automotive industry, aerospace, medical devices and many other fields, helical compression springs directly determine the stability, safety and service life of end products.

For a long time, the core manufacturing technologies for high-end helical compression springs worldwide have been monopolized by a small number of enterprises from countries and regions such as the United States, Europe and Japan.

Through technological secrecy, patent barriers and other means, these enterprises have long dominated the industry discourse, leaving domestic companies dependent on imported technologies or low-end imitation.

This has not only led to high procurement costs and long delivery cycles, but also exposed key sectors to the risk of being "strangled" in core technologies, seriously restricting the upgrading and development of related industries in China.

It is understood that foreign enterprises have maintained a technological blockade in this field for more than ten years, and domestic enterprises have repeatedly encountered obstacles in research and development of core processes and performance optimization.

Faced with the dilemma of foreign technological monopoly, Cinmea Technology has adhered to independent innovation, established a professional R&D team, and invested heavily in human, material and financial resources to tackle key technical difficulties such as structural design and fatigue performance of helical compression springs.

During the research and development process, the team abandoned traditional design concepts, broke away from the restrictions of foreign patent barriers, optimized the helical structure and parameter configuration of springs in line with the actual needs of domestic industries, and innovatively adopted new forming and treatment technologies.

After countless tests, adjustments and improvements, the company successfully developed this helical compression spring technology with independent intellectual property rights, which passed the rigorous examination of the China National Intellectual Property Administration and was granted a patent.

Compared with similar foreign technologies and traditional springs, the patented helical compression spring technology developed by Cinmea Technology shows remarkable advantages, with comprehensive improvements especially in performance and cost.

In terms of operational performance, the patented technology enables more efficient storage of elastic potential energy and more uniform stress distribution in the spring.

Its fatigue life is increased by more than 30% compared with traditional springs, allowing it to adapt to more complex and demanding working environments.

It maintains stable performance even under high-frequency vibration or extreme temperature conditions, effectively solving the pain point of high-cycle fatigue fracture in traditional springs.

In addition, the technology also meets green and environmental protection requirements.

Material utilization rate is 15% higher than that of foreign technologies, aligning with the current low-carbon development trend of the global manufacturing industry and complying with international compliance requirements such as EU REACH regulations and ISO 14067:2024, laying a foundation for products to enter the international market.

A relevant person in charge of Cinmea Technology stated that the grant of this helical compression spring patent is an important achievement of the company’s commitment to independent innovation and deep cultivation of core technologies, as well as a critical step in breaking foreign technological monopolies and realizing the localization of high-end spring manufacturing.

In the future, the company will further increase R&D investment, promote the industrialization of this patented technology, expand production scale, and improve product quality and capacity.

At the same time, it will continue to focus on the spring manufacturing sector, address industry demands, conduct research on more core technologies, continuously break through technical bottlenecks, drive the transformation of China’s spring manufacturing industry from "low-end imitation" to "high-end independence", and support the high-quality development of related downstream industries.

Industry insiders pointed out that by breaking the more than decade-long foreign technological blockade, Cinmea Technology has not only gained the initiative in the market for itself, but also set a benchmark for independent innovation for similar domestic enterprises.

With the wide application of this patented technology, domestic industries will effectively reduce their dependence on imported springs in this field, promote the supply chain independence and controllability of China’s rail transit, machinery manufacturing, automotive, aerospace and other industries, and carry important practical and long-term significance for enhancing the core competitiveness of China’s high-end manufacturing industry.
