Custom Electrical Contact Components
Products Description
In rail transit signal control and power switching systems, the reliability of track switch contacts directly affects the safety and stability of line operation. The "heart" of this core component is Custom Electrical Contact Components. As a core product of APOLLO's electrical metal solutions, developed since 1990, our products, thanks to their precise silver-copper composite process and stringent quality control, have become a trusted choice in the global rail transit and high- and low-voltage electrical appliance sectors. From the conductivity of the contacts to the fitting precision of the structure, from the durability against arc erosion to the adaptability to extreme environments, every detail is designed for efficient and safe electrical connections.
Key Selling Points
Precise Silver Contact Integration
Utilizing Silver Contact Brazed Assemblies technology, silver contacts are firmly bonded to the copper substrate, ensuring stable contact resistance and suitability for high-frequency switching applications.
High Cost-Effectiveness from Factory Direct Supply
Our own factory enables factory-direct pricing, resulting in lower costs than the industry average for equivalent quality. Small-batch customization is also supported.
Fully Certified Quality Assurance
Silver Contact Brazing on Copper Bars is certified by international standards such as ISO9001-2015, IATF16949, RoHS, and REACH, meeting the stringent safety and environmental requirements of the electrical industry.
Efficient Delivery and Free Samples
Standard order lead time is only 7-15 days. Free samples of Resistance Projection Welding Silver Contact are available for customers to test performance and compatibility.
Metal Forming and Manufacturing Processes
Precision Stamping and Forming: High-precision molds are used for stamping, bending, and stretching of metal strips to form precisely dimensional contact bases and structural components.
Advanced Connection Technologies: Core technologies include brazing, resistance projection welding, and resistance butt welding. The Silver Contact Brazing on Copper Bars process enables metallurgical bonding between the silver layer and the copper substrate, while resistance welding is suitable for high-efficiency mass production.
Heat Treatment and Strengthening: Heat treatment processes such as annealing and quenching adjust the internal crystal structure of the metal, eliminate internal stress, and improve the material's hardness, toughness, and overall mechanical properties.
Surface Finishing: This includes polishing, cleaning, and electroplating (such as silver plating and nickel plating) to improve Resistance Butt Welding Silver Contact appearance, enhance corrosion resistance, and optimize the contact surface condition.
