Key Selling Points
High-Performance Electromagnetic Conduction System: The AC Rod is made of high-quality DT4C material, possessing excellent soft magnetic properties. Our products exhibit extremely low coercivity and high permeability in alternating magnetic fields, ensuring stable electromagnetic response characteristics during high-speed switching.
Precision Copper Terminal Riveting Technology: Our products utilize advanced AC Core Riveted with Copper Terminal technology, achieving a precise connection between the iron core and copper terminals through automated riveting equipment. This structure not only optimizes the current conduction path but also significantly improves the product's conductivity and mechanical strength, ensuring no loosening or poor contact occurs under long-term, high-frequency use.
Diverse Product Specifications: We offer a full range of product specifications, including Grooved Core for AC Relay, covering different sizes, slot designs, and mounting methods to meet the comprehensive application needs from miniature relays to industrial-grade high-power relays.
Complete Supply Chain Integration Capabilities: As a professional manufacturer with its own factory, we possess the comprehensive capability to produce all metal parts required for relays, including Core Pins, enabling one-stop procurement services.
Metal Forming Process
Cold Forging
For large-volume production of standard-sized AC Relay Cores and Copper Rings, cold forging is the preferred process. With a material utilization rate exceeding 95%, intact internal streamlines, and 30% higher mechanical strength compared to machined parts, the soft magnetic properties are maintained without degradation during processing.
Riveting and Assembly
Riveting of copper terminals and the iron core utilizes a servo press-fitting machine with real-time pressure curve monitoring to ensure consistent riveting depth and pull-out force. The Pure Iron Core for AC Relay, combined with copper rings and terminals, allows for fully automated assembly, minimizing human error.
Deburring and Cleaning
All machined parts undergo magnetic abrasion or high-pressure water deburring, followed by ultrasonic cleaning to remove oil and grease. This ensures a clean, shaving-free surface on the Relay Steel Core, preserving the relay's insulation performance after assembly.
Application Areas
Industrial Relays
As AC Cores for Industrial Relays, they are widely used in machine tools, PLCs, and distribution boxes, ensuring the stable operation of automated production line control.
