Products Description
Our professionally manufactured Relay Core and Iron Core for Relay are the core magnetic components of the relay's electromagnetic system, directly determining the relay's attracting force, response speed, and lifespan stability. Utilizing our own cold heading factory and dedicated pure iron material production line, we offer a full range of iron core components. Each batch strictly adheres to ISO9001-2015 and IATF16949 standards and supports surface treatments such as nickel plating, zinc plating, and rust prevention. We provide relay assembly plants with highly consistent and cost-effective metal core components at factory-direct prices, with flexible customization capabilities and complete testing data.

Product Details and Structural Disassembly
Head Structure Details
The head of the Soft Magnetic Iron Rod RFe80 is manufactured using high-precision cold forging, resulting in a smooth end face and burr-free edges. This allows for a perfect fit with the relay's armature structure, ensuring uniform electromagnetic attraction and improving the relay's engagement reliability.
Rod Structure Details
The Relay Rod features high cylindricity, a smooth surface, and precise dimensional tolerances. It easily accommodates the relay coil frame, ensuring coaxiality between the coil and the iron core and improving electromagnetic efficiency.
Overall Structural Disassembly
The Soft Iron Core in Relay consists of two parts: the head (force-bearing and contact surface) and the rod (coil assembly part). The head transmits electromagnetic attraction, while the rod mounts the coil. The structural design conforms to the electromagnetic principles of a relay, maximizing electromagnetic conversion efficiency.
