Zhejiang Jifeilong Instrument Technology Research Division
In the high-precision world of 21st-century manufacturing, the quality of a component is often defined by what is removed rather than what is added. Deburring stainless steel has evolved from a simple finishing task into a sophisticated engineering necessity. As a leading Wholesale Deburring Stainless Steel Supplier & Factory, we recognize that the presence of even microscopic burrs on stainless steel pins, shafts, or valve cores can lead to catastrophic failure in electrical systems like Molded Case Circuit Breakers (MCCB) or critical automotive charging infrastructures.
Why Deburring Matters:
New Energy Vehicle (NEV) charging piles require components that can withstand high current without heat buildup. Our deburring processes for charging pile connectors ensure surface integrity, reducing resistivity and enhancing thermal performance.
For MCCB and MCB manufacturers, our deburred rivets and shafts are the backbone of safety. By eliminating sharp edges, we ensure that the mechanical movement of the breaker is instantaneous and reliable over thousands of cycles.
Water valve accessories and solenoid valve cores require perfectly smooth surfaces to maintain airtight and watertight seals. Our precision grinding and deburring technology eliminates micro-cracks where corrosion often begins.
Years of Expertise
Global Enterprises
Quality Certified
Automated Production
Zhejiang Jifeilong Instrument Technology Co., LTD. (formerly Yueqing Feilong Instrument Factory) was established in September 1999. Located at the Oujiang Port in Wenzhou City, we have pioneered the integration of production, processing, grinding, and deburring departments under one roof.
We mainly engage in the integrated manufacturing and sales of various electrical switches, shafts, plastic products, and hardware components. Our products are widely used in home appliances, solenoid valves, electronics, automobiles, filtration equipment and other fields. By implementing strict quality control in every production link, from raw material procurement to finished product delivery, the company has passed the ISO9001 certification.
Through technological and equipment transformation, we have achieved fully automated production capacity. Our adherence to the tenet of "seeking truth from facts and quality first" has earned us the trust of over 100 enterprise customers globally.
The global demand for high-precision deburred stainless steel is projected to grow significantly as industrial automation and electrification accelerate. In North America and Europe, the shift toward Renewable Energy and Electric Vehicles (EV) has created a "Zero-Defect" procurement mandate. As a China-based factory, we leverage our geographic advantage in the Wenzhou industrial cluster to provide cost-effective yet high-specification solutions that meet German DIN and American ASTM standards.
The next phase of stainless steel deburring involves Cryogenic Deburring and Electrochemical Polishing. These technologies allow for the removal of burrs from internal cavities of complex valves without affecting the dimensional tolerance of the part. Zhejiang Jifeilong is currently investing in AI-vision inspection systems that detect surface irregularities at the micron level, ensuring 100% pass rates for high-stakes aerospace and medical components.
Stainless steel is a tough material; during machining, it often leaves "flash" or burrs. In electrical components like circuit breakers, these burrs can cause mechanical jams or electrical arcing, which are major safety hazards.
