Products Description
The Electromagnet Core is a key magnetic metal component installed inside the frame of various relays. It is responsible for magnetic circuit closure and energy conversion, playing a decisive role in the attraction force, release speed, and overall reliability of the relay. This product is manufactured using high-purity magnetic materials and cold heading technology.
Superior Material Properties
High-Purity Soft Magnetic Material
Utilizing specific grades of Coil Soft Iron Core raw materials ensures extremely low carbon, sulfur, and oxygen content, achieving high saturation magnetic induction (Bs≥2.15T) and high initial permeability.
Low Hysteresis Loss
Optimized annealing processes significantly reduce coercivity (Hc), minimizing Electrician Pure Iron Core energy loss and heat generation in alternating magnetic fields.
Excellent Long-Term Stability
The Pure Iron Core material undergoes special aging treatment to ensure stable magnetic properties under long-term use or environmental temperature fluctuations.
Key Process Control Points
Dimensional Control
Equipped with a high-precision coordinate measuring machine, daily random checks of work-in-process are conducted, with a focus on monitoring core assembly for Relay Core Cold Heading dimensions to ensure that the critical dimension CPK ≥ 1.67, achieving stable control over dimensional accuracy and meeting the precision assembly requirements of relays.
Surface Quality Control
Through multiple polishing and cleaning processes, surface roughness is strictly controlled to Ra ≤ 0.8μm. Combined with an automatic CCD inspection and sorting machine, Pure Iron Cores with defects such as cracks and burrs are accurately identified and rejected, ensuring the core's magnetic conductivity efficiency and assembly safety.
Weight Control
Equipped with an automatic weighing and sorting system, the weight of individual Coil Soft Iron Cores is monitored in real time, controlling the weight tolerance within ±0.5%, avoiding the impact of weight deviation on the consistency of relay engagement force.
Leading Manufacturing Processes
| 40% Increased Production Efficiency | High-speed continuous forming significantly shortens delivery cycles, meeting customers' high-volume demands for Electrician Pure Iron Core. |
| Up to 98% Material Utilization | Near-net-shape forming technology greatly reduces Coil Soft Iron Core raw material waste, helping customers achieve cost and environmental goals. |
| Revolutionary Improvement in Consistency | The Cold Heading process ensures complete metal flow lines and refined grains in the Pure Iron Core, resulting in significantly better batch-to-batch and batch-to-batch consistency in magnetic properties and dimensions compared to machined parts, laying the foundation for uniform relay performance. |
