• Types of Springs Offered:

Heli Spring offers a comprehensive portfolio of high-precision springs tailored to meet the exacting demands of diverse industries. Among its flagship products are compression springs, tension (extension) springs, torsion springs, wave springs, flat springs, and custom wire-formed components—all engineered for superior performance and reliability. Each spring type is meticulously designed using advanced CAD software and manufactured with state-of-the-art CNC machines and automated stamping lines. For instance, Heli’s compression springs are widely used in automotive suspension systems and electronic device switches, where consistent force and long-term durability are critical. Tension springs play a vital role in fitness equipment and garage door mechanisms, providing controlled retraction forces. The company’s wave springs—ideal for space-constrained applications—have been adopted in precision instruments and medical devices, offering up to 50% space savings compared to traditional coil springs. Meanwhile, custom wire-formed parts, such as those used in seatbelt tongue plates and SIM card trays, demonstrate Heli Spring’s ability to integrate multiple mechanical functions into a single component. These innovations are backed by extensive material selection—including stainless steel, phosphor bronze, titanium alloy, and enameled wire—and a wide array of surface treatments like nickel plating, black oxide, and electrophoresis, ensuring corrosion resistance and aesthetic finish. Every product line is developed with a focus on functionality, longevity, and compliance with international standards such as RoHS, REACH, and ELV, making Heli Spring a preferred supplier for global brands seeking both quality and sustainability.

• Customization and Quality Control:

At the heart of Heli Spring’s success lies its robust customization capability and rigorous quality control framework. With over 31 years of experience in spring and stamping part manufacturing, the company maintains a professional R&D department equipped with 50 sets of advanced testing equipment and a fully functional laboratory. This enables precise evaluation of spring characteristics such as load capacity, fatigue life, and dimensional accuracy. Customers can request custom designs based on specific load requirements, operating environments, or spatial constraints—whether it’s a micro-spring for a wearable medical device or a heavy-duty connector pin for industrial machinery. Heli Spring leverages its proprietary design software and rapid prototyping capabilities to reduce time-to-market, often delivering samples within 7–10 days. All products undergo multi-stage inspection: raw material verification, in-process checks during production, and final acceptance testing before shipment. The company’s adherence to IATF16949 ensures every batch meets automotive-grade quality standards, while certifications like RoHS and REACH guarantee environmental compliance. Furthermore, Heli Spring holds multiple patent applications, including innovative solutions such as a detection device for spring manufacturing and a circlip for AC contactors—proof of its forward-thinking approach. This combination of agility, precision, and traceability allows Heli Spring to serve clients ranging from startups to Fortune 500 companies with confidence and consistency.

--- Competitive Advantages ---

• Experience and Expertise:

With more than three decades of hands-on experience in spring manufacturing, Wenzhou Heli Spring Manufacturing Co., Ltd. has cultivated a deep reservoir of technical knowledge and operational excellence. Since its founding in 1992, the company has continuously refined its processes, transitioning from manual production to a fully automated, data-driven manufacturing ecosystem. This evolution has enabled Heli Spring to maintain exceptional consistency in product quality, even at high volumes. The company operates over 200 sets of automated equipment and employs a team of seasoned engineers who specialize in material behavior, stress analysis, and failure mode prediction. Their expertise is evident in real-world projects, such as supplying precision compression springs for Huawei’s smartphone battery contacts—where tolerance levels below ±0.05mm were required. Another notable example includes the development of a custom torsion spring for Schneider Electric’s circuit breakers, which had to withstand extreme temperature fluctuations and repeated cycling without deformation. These successes stem from Heli Spring’s culture of continuous improvement and investment in human capital. Employees regularly participate in training programs on lean manufacturing, Six Sigma, and new material technologies. Additionally, the company’s dual-location setup—Wenzhou and Kunshan—allows for optimized supply chain management and faster response times. With a registered capital of 10.68 million yuan and a strong financial foundation, Heli Spring continues to reinvest in R&D and infrastructure, ensuring long-term competitiveness. Its status as a ‘National High-Tech Enterprise’ and ‘Specialized, Refined, Peculiar and Novel Enterprise’ is not just a label—it’s a reflection of its proven track record in innovation, scalability, and market responsiveness.

--- Key Partnerships and Collaborations ---

• Notable Clients and Projects:

Heli Spring’s reputation is built on enduring partnerships with some of the world’s most respected brands across automotive, electronics, and industrial sectors. One standout case involves its collaboration with BYD Auto, where Heli Spring supplied high-torque torsion springs for electric vehicle door hinge systems. These springs were required to endure over 100,000 cycles without fatigue failure—a challenge met through meticulous material selection (60Si2Mn alloy) and heat treatment optimization. Similarly, Heli Spring partnered with Delixi Electric to develop a series of wave springs for miniature relays used in smart home appliances. The compact design saved 40% of axial space while maintaining a stable preload force, directly contributing to the miniaturization trend in consumer electronics. Another significant project involved working with Volkswagen Automobile to produce customized compression springs for engine valve assemblies. The springs were subjected to extreme thermal and mechanical stress, requiring strict adherence to IATF16949 standards. Heli Spring delivered defect-free batches across multiple production runs, earning a repeat order and a formal recognition letter from the client. Beyond OEMs, Heli Spring has also supported medical device innovators like LYITECH Liyi Intelligent Manufacturing, supplying flat springs for robotic surgical tools where precision and biocompatibility were non-negotiable.
