Products introduction
In 2025, the global manufacturing industry is undergoing a new round of technological revolution: the penetration rate of new energy vehicles has exceeded 35%, the shipment of smart home devices is increasing by 22% annually, and the coverage rate of industrial automation production lines has exceeded 60%. Behind these trends is the explosive demand for core electrical components such as relays, contactors, circuit breakers, and switches. As the "heart" of such components, Silver Contacts have become the focus of the industrial chain-their performance directly determines the reliability, lifespan, and safety of electrical equipment.
Manufacturing Process
The manufacturing process of Solid Silver Contact includes many precise steps, from raw material inspection to finished product formation. First, an X Spectrometer is used to analyze the composition of raw metals like silver and copper. This ensures their purity and alloy ratios meet process requirements. At the same time, a Tool Microscope checks the precision of molds and cutters. This builds a solid foundation for accurate later processing.
Next, the process moves to the Material Inspection of the Alloy Silver contacts. Here, the appearance and performance of raw materials like silver wires and copper wires are checked one by one. Qualified blanks are selected. Then, EDM (Electrical Discharge Machining) is used to make tungsten steel molds. These molds are hard and wear-resistant, and they are key tools for cold heading.
The Cold Heading process is key to shaping the initial form of Silver Contact Points. At room temperature, blanks are pressed to undergo plastic deformation. They initially form semi-finished contacts with basic structures like rivets. After that, semi-finished products go through Ultrasonic Cleaning. This completely removes oil and processing debris from the surface. If they are alloy contacts like silver tin oxide, they also need Sintering. This process makes metal powders bond tightly, strengthening structural strength and conductivity.
After Sintering, Passivation is done. It creates a protective film on the Silver Electrical Contacts surface, effectively resisting oxidation and corrosion. Next is the Sorting stage. Manual or automated equipment checks the dimensional accuracy and appearance integrity of contacts. Unqualified products are rejected. At the same time, professional equipment tests the thickness and uniformity of the silver layer.

Development Trends
