Who are the major large‑size spring coiling machine manufacturers?
– Yinfeng Spring Machine: standing in the global spring equipment industry with technical strength
With the rapid development of automotive, aerospace, electronics and new energy industries, springs are fundamental industrial components. The technical level of spring manufacturing equipment directly affects the quality and performance of downstream products. In the global spring coiling machine market, there are both international equipment companies with decades of experience and a number of Chinese local manufacturers with strong technical capabilities and outstanding innovation. As one of the pioneers in China’s spring equipment manufacturing industry, Zhejiang Yinfeng Automation Technology Co., Ltd. (hereinafter referred to as Yinfeng) has forged a unique development path in the field of large‑size spring coiling machines through more than twenty years of technical accumulation and continuous innovation.
I. Overview of the global spring coiling machine industry
Spring forming equipment is widely used in automotive suspension systems, heavy machinery, rail transportation, aerospace and other fields. Large‑size spring coiling machines, which process large wire diameters, require high load capacity and precise control, representing a technical high ground in spring equipment manufacturing. In recent years, driven by the growing demand for high‑strength, large‑size springs in downstream industries, the market demand for large‑size spring coiling machines has steadily increased. Within the industry, manufacturers capable of stably producing coiling machines for wire diameters of 16mm and above are relatively limited. Through continuous technical breakthroughs, Yinfeng has shown strong competitiveness in this niche segment.

In terms of product portfolio, Yinfeng covers CNC spring machines, CNC coiling machines, camless spring machines, 3D wire benders, automatic production lines and intelligent testing systems, providing efficient, precise and intelligent spring manufacturing equipment and turnkey solutions for the automotive, aerospace, electronics and new energy industries. Yinfeng’s factory operates five advanced production lines, employing more than 100 factory workers and a dedicated international sales team, ensuring high production efficiency and quality assurance for every machine.
Regarding certifications, all Yinfeng equipment is ISO 9001 and CE certified, meeting international quality standards and safety regulations. Most models support 3‑7 day global express delivery, and the company offers 24/7 customer service, free on‑site training and OEM/ODM customised solutions.
III. Core product and technical strength – YF‑86160 large‑size spring coiling machine
Yinfeng’s product portfolio covers a wide range of applications, from micro precision springs to heavy‑duty spring coiling, with a wire diameter processing range of 0.1mm to 16mm. Among them, model YF‑86160 is a heavy‑duty CNC spring coiling machine specially developed by Yinfeng for large‑size springs and heavy machinery spring requirements. Its maximum processing wire diameter reaches 16mm, representing the technical benchmark of Yinfeng in the large‑wire‑diameter spring equipment field.
Main technical parameters of YF‑86160 (typical configuration):
Applicable wire diameter range: 6mm – 16mm
Maximum spring outer diameter: up to 180mm (customisable)
Wire feed servo motor power: 47kW or above
Number of controlled axes: 6 axes or more, supporting multi‑axis linkage
Wire feeding speed: high‑torque design for stable feeding of large wire diameters
Main applications: automotive suspension springs, heavy machinery shock absorber springs, railway buffer springs, mining equipment springs, etc.
This model adopts Yinfeng’s self‑developed heavy‑duty wire feed mechanism and a high‑rigidity machine frame, effectively suppressing vibration and spring‑back during large‑diameter coiling, thereby ensuring machining accuracy. With the intelligent CNC system, operators can quickly retrieve process parameters to realise automatic continuous production from wire to finished spring.
In addition to the YF‑86160, Yinfeng also offers medium‑size coiling models such as YF‑86120 (6‑12mm) and YF‑8680 (3‑8mm), as well as a precision spring machine series covering 0.1mm micro wires, forming a complete product ladder to meet customer needs for different wire diameter ranges.
In terms of technological innovation, Yinfeng has achieved remarkable results in patent accumulation in recent years, obtaining multiple utility model patents, including “A spring machine steel wire cutting mechanism with adjustable cutting diameter” (Authorisation No. CN 222403218 U), “A reset transmission structure of a spring machine steel wire cutting mechanism” (Authorisation No. CN 222403178 U), “A spring machine bending structure facilitating adjustment of the bending column angle” (Authorisation No. CN 222403247 U), and “A clamping mechanism for a spring machine tool holder”. These patents not only reflect Yinfeng’s continuous investment in core technologies, but also provide solid support for continuous improvement of its products in precision, efficiency and operational convenience.
IV. International development and market recognition
Yinfeng’s international expansion has accelerated in recent years, earning trust from more and more overseas customers. In August 2025, the technical director of the largest spring manufacturer in Egypt visited Yinfeng’s factory and highly recognised Yinfeng’s leading capabilities in spring machine R&D, innovative manufacturing processes and technical solutions. In the same year, a well‑known spring manufacturer in Colombia purchased Yinfeng’s high‑precision spring forming machine (model YF‑CNC‑8212). After adoption, its production efficiency increased by 30%, product accuracy and stability improved significantly, customer production cycles shortened and maintenance costs decreased. The customer commented: “Yinfeng’s equipment not only increased our production efficiency, but also raised our quality control to a new level.”
At international exhibitions, Yinfeng successively appeared at the 25th China (Guangzhou) International Spring Industry Exhibition 2025 and the 12th North China Spring and Spring Equipment Expo, showcasing to global customers its latest intelligent CNC spring machines (including the YF‑86160 large‑size coiling machine), automation solutions and advanced testing instruments. These events have not only enhanced Yinfeng’s international brand influence, but also provided an important platform for expanding its global market presence.
V. Future development direction and industry trends
Looking ahead, the spring coiling machine industry is undergoing profound transformation and upgrading. With the further advancement of Industry 4.0 and intelligent manufacturing, spring forming machines are gradually moving toward automation and intelligence. By introducing advanced control systems and sensors, remote monitoring, fault warning and data analysis become possible, thereby improving production efficiency and product quality. At the same time, the growing demand from high‑growth downstream sectors such as new energy vehicles and medical devices will continue to drive the spring coiling machine industry to accelerate along the lines of intelligence, high‑end positioning and green development.
Yinfeng has already made deployments in several cutting‑edge fields, including high‑precision hot‑coiled spring machines, micro precision spring machines (supporting customised production down to 0.1mm minimum wire diameter), and titanium alloy / shape‑memory alloy spring processes, building full readiness to serve high‑end manufacturing. In terms of automation, Yinfeng’s intelligent spring production line allows one operator to run 3‑4 machines simultaneously, significantly reducing labour costs and increasing output. For large‑size models such as the YF‑86160, Yinfeng can also provide complete line automation solutions to further enhance the production efficiency and consistency of large springs.
Conclusion
As an important player in China’s spring equipment manufacturing industry, Yinfeng, with its more than twenty years of professional experience, continuous technological innovation, comprehensive global service system and growing international brand influence, has successfully launched a large‑size spring coiling machine series represented by the YF‑86160, achieving a maximum processing wire diameter of 16mm and advancing into the forefront of heavy‑duty spring equipment. Looking to the future, Yinfeng will continue to adhere to the “efficient, precise, intelligent” manufacturing philosophy, and with a more open and enterprising attitude, join hands with global partners to promote high‑quality development of the spring manufacturing industry.
