Industry-leading fasteners and electrical hardware engineered to international standards.
In the modern industrial ecosystem, the Metal Split Pin (often referred to as a cotter pin) serves as a critical safety component. Despite its simple appearance, its role in preventing rotational movement or securing components in place is foundational to mechanical integrity. From high-speed automotive transmissions to heavy-duty industrial valves and sensitive electrical switchgear, the demand for high-precision, corrosion-resistant split pins has seen a 15% year-over-year growth in the global market.
The shift toward Smart Manufacturing (Industry 4.0) and New Energy Vehicles (NEV) has redefined the specifications for metal split pins. Suppliers are no longer just delivering "hardware"; they are delivering "performance guarantees." Manufacturers like Zhejiang Jifeilong Instrument Technology Co., LTD are at the forefront of this evolution, integrating advanced metallurgy with automated cold-heading and precision-forming technologies.
Leveraging China's manufacturing clusters in Zhejiang, we utilize fully automated production lines that reduce lead times by 30% compared to traditional workshops.
Our pins utilize high-grade Stainless Steel (304/316), Brass, and Carbon Steel with specialized coatings to withstand 500+ hours of salt spray testing.
Designed for the extreme thermal environments of NEV charging piles and the mechanical stress of high-voltage circuit breakers.
Located at Oujiang Port, Wenzhou, our factory benefits from a dense supply chain ecosystem. This proximity allows for immediate access to high-quality raw materials and specialized heat-treatment services. For global enterprises, sourcing from a China-based OEM manufacturer like Jifeilong translates to a significant reduction in Total Cost of Ownership (TCO) without compromising on the E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) standards required by top-tier engineering firms.
Zhejiang Jifeilong Instrument Technology Co., LTD. (formerly Yueqing Feilong Instrument Factory) was established in September 1999. Over the past two decades, we have evolved from a local workshop into a global high-tech enterprise. Our core mission is to be the "High-Quality Global Supplier of Components," specializing in electrical switches, shafts, hardware components, and precision split pins.
With the implementation of strict quality control across every production link—from raw material procurement to finished product delivery—we have successfully passed the ISO9001 certification. Our vision, "Reputation Supreme, People-Oriented, Quality as the Root," drives our continuous investment in automated manufacturing and technical innovation.
