In the realm of high-precision assembly, Metal Dowel Pins serve as the invisible backbone of structural integrity. Unlike standard bolts or screws, a dowel pin’s primary function is to absorb shear stress and maintain absolute alignment accuracy between mating components. As a leading OEM Metal Dowel Pins Manufacturer, Zhejiang Jifeilong Instrument Technology Co., Ltd. understands that a deviation of even a few microns can compromise the functionality of complex electrical switches or automotive assemblies.
Our technical roadmap integrates advanced metallurgy with "Sub-Micron Sensitivity." Whether it is for Molded Case Circuit Breakers (MCCB) or New Energy Vehicle (NEV) connectors, our pins provide the critical tolerance required for zero-failure industrial environments.
We utilize high-grade GCr15 bearing steel, SUS304/316 stainless steel, and specialized alloys that offer optimal hardness-to-toughness ratios, ensuring durability under cyclical mechanical loads.
Our production line achieves tolerances within h6 to m6 ranges, utilizing centerless grinding technology to ensure perfectly cylindrical profiles for interference fits.
From passivating and galvanizing to advanced PVD coatings, we enhance the corrosion resistance of hardware used in saline or high-humidity environments.
Established in September 1999 (formerly Yueqing Feilong Instrument Factory), we have spent over two decades mastering the art of precision hardware. Located at the Oujiang Port in Wenzhou City, our facility is a hub of innovation for electrical switches, shafts, plastic products, and hardware components.
Our products are ubiquitous in home appliances, solenoid valves, electronics, and the rapidly growing Automobile and EV sectors. By implementing strict quality control from raw material procurement to finished product delivery, we have secured our ISO9001 certification, ensuring that every metal dowel pin or rivet meets global benchmarks.
"Seeking truth from facts and quality first"—this is not just our motto; it is our engineering philosophy.

Located in the heart of China’s industrial belt, we have direct access to premium steel mills and logistics hubs, ensuring price stability and rapid delivery.
We provide rapid prototyping and free samples. Our engineering team acts as an extension of your own, optimizing designs for "Manufacturability" (DFM).
Specialized pins and shafts for MCCBs and MCBs. We focus on mechanical life cycles, ensuring that components can withstand thousands of switching operations without fatigue.
High-conductivity and high-strength pins for charging connectors and battery management systems, meeting the rigorous vibration and thermal requirements of the automotive sector.
Durable valve cores and nozzle components that offer precision fluid regulation for solenoid valves and filtration equipment.
We implement strict protocols at every stage—from spectrum analysis of raw materials to automated optical inspection (AOI) of final shipping items.
Our team is available 24 hours a day to provide design-in support, ensuring our pins integrate perfectly with your assembly lines.
By removing the "middleman," we offer factory-direct pricing and transparent communication, reducing the Total Cost of Ownership (TCO).
Zhejiang Jifeilong Instrument Technology Co., Ltd.
📍 Oujiang Port, Wenzhou City, China
Tenet: Quality First, Reputation Supreme, People-Oriented.
Strategic Goal: To provide the precision foundations for global industry with excellence and innovation.
The next decade of hardware manufacturing will be defined by Smart Materials and Internet of Things (IoT) integration. Jifeilong is currently researching:
Developing high-strength aluminum and titanium pins for the aerospace and drone industries to reduce payload without sacrificing structural rigidity.
Implementing nano-coatings that reduce friction in moving assemblies, extending the maintenance intervals for industrial machinery.
Preparing for future compliance by offering batch-level traceability for aerospace and medical-grade hardware components.
Steel alloys like 4140, 52100 (GCr15), and 300/400 series Stainless Steel are standard. Choice depends on required hardness, corrosion resistance, and magnetic properties.
Yes, we specialize in OEM/ODM. We can manufacture pins with non-standard diameters, lengths, and specialized chamfer profiles based on your CAD drawings.
Every production batch undergoes rigorous sampling. We provide material certifications and dimensional inspection reports upon request.
Standard orders are processed in 3-5 days. For high-volume custom production, lead times typically range from 2 to 4 weeks depending on the complexity.
