With the development of electronic technology and industrial automation, Movable Contact Rivet has been widely adopted in many industries, including home appliances, transportation, electric power, telecommunications, machinery and equipment, among others. It has become an indispensable component in electrical control and transmission. Our products, featuring high electrical conductivity, excellent wear resistance and long service life, can effectively improve equipment performance and reliability, reduce maintenance costs, and bring higher added value to customers.
Production Process
Vacuum Melting And Homogenization Of Raw Materials
Moving Contacts are manufactured using a vacuum melting process, in which silver base material is precisely proportioned and melted with wear-resistant and arc-resistant alloys. This process prevents impurity contamination and ensures uniform material composition. After melting, homogenization annealing is applied to eliminate internal stress, optimize grain structure, and improve hardness and mechanical strength, laying a solid foundation for wear and arc resistance.
Precision Forming And Pre‑Strengthening For Dynamic Adaptation
Based on the contact structure and operating requirements, precision forming is completed with high-precision molds, accompanied by low-temperature pre‑strengthening treatment. This reduces machining deformation, enhances structural stability, and enables Active Contacts to withstand high-frequency operating impacts.
Contact Surface Strengthening and Precision Polishing
The contact surface of Dynamic Contacts undergoes specialized carburizing or ion implantation strengthening to form a wear‑resistant and arc‑resistant layer. Mirror polishing is then performed to remove surface marks, reduce friction, ensure stable contact resistance, and avoid poor contact caused by uneven wear.
Dynamic Simulation Testing and Finished Product Calibration
The performance of Moving Contact for Electromagnetic Relays is tested under simulated real-world conditions of high-frequency operation and arc impact to screen out non-conforming products. Qualified products are precisely calibrated in dimensions and operating angles to ensure consistency and dynamic adaptability in batch production.

Adequate Structural Rigor
Through the molding process and structural optimization, the Movable Silver Contact for Contactor features high overall rigidity and mechanical strength. It withstands impact and friction under high-frequency operation without deformation, cracking or bending, ensuring accurate and reliable switching with no risk of structural failure.
Controlled Arc-Resistant Traces
The contact end face of the Movable Contact Rivet is treated for arc resistance, providing excellent ablation resistance and minimal trace retention. It ensures stable contact resistance, low current loss and smooth conduction during long-term use, enhancing equipment energy efficiency and service life.
Precise and Consistent Dimensions
Key dimensions, angles and flatness are precisely controlled. Moving Contact from the same batch achieves high consistency, enabling direct use on automated assembly lines with accurate fitting, no sticking and stable contact, thus improving assembly yield and equipment reliability.
Smooth and Burr-free Surface
Active Contact undergoes precision polishing and deburring, resulting in a smooth surface without sharp edges. It delivers low friction, fast response and no jamming, suitable for high-frequency on-off operations while avoiding scratches on mating components.
Product Advantages
Wear Resistance & Arc Resistance: To address the pain points of high-frequency friction and arc impact on Dynamic Contact, exclusive wear-resistant silver alloy formulas (including silver-tungsten, silver-nickel, and silver-tin oxide) are adopted. These formulas significantly improve hardness and arc ablation resistance, solving the issues of easy wear and burn-off of pure silver contacts. Meanwhile, they maintain excellent electrical conductivity with stable contact resistance, making them suitable for high-frequency dynamic conduction.
High Operating Flexibility: The structure and surface finish of the Moving Contact for Electromagnetic Relay are optimized for high-frequency operation requirements, reducing friction resistance to ensure sensitive and smooth response without jamming. Precise control of dimensions and weight guarantees accurate and reliable fitting, enabling stable switching under high-frequency start-stop conditions, thus enhancing equipment operational reliability and response speed.
Oxidation & Corrosion Resistance: Suitable for harsh and complex environments such as industrial and automotive applications, Moving Silver Contact is enhanced with surface treatment to improve oxidation resistance, sulfidation resistance, and corrosion resistance. It is not prone to blackening or sulfide layer formation during long-term use, avoiding poor contact and jamming, extending service life, and reducing maintenance costs.
