Products Description
In the field of low-voltage electrical apparatus, Brazed Silver Contact Stamped Parts are recognized as one of the most technically sophisticated components. Compared with simple riveting or resistance welding, brazing uses molten filler metal to fill the tiny gaps between contacts and stamped parts under capillary action, forming a dense metallurgical bonding layer. This bonding layer is not only a physical connection but also the core channel for electrical conduction and heat transfer.
With more than ten years of intensive focus on brazing technology, Xiamen Apollo Electrical is well aware of the decisive influence of the microstructure of the welding interface on macroscopic properties. Under a microscope, our Silver Contact Brazed on Stamped Part exhibits a distinct three-layer structure. This multi-layer structure ensures that the contacts will not fall off under high-current impact, will not loosen during frequent on-off operations, and will maintain stable contact resistance under temperature rise variations.
Production Process
Precision Mold Debugging and Stamping Forming
Customized high-precision stamping molds are adopted. Before production, professional engineers complete mold calibration and parameter optimization to ensure accurate control of key dimensions of stamped parts such as hole positions, contours and thicknesses. The whole stamping process is under automatic control, with special fixtures fixing base materials to avoid defects like warpage, burrs and edge chipping of stamped parts. This ensures each Silver Contact Resistance Welded Stamping has a regular structure and consistent dimensions, laying a foundation for the subsequent brazing process.
Precise Positioning and Pretreatment of Silver Contacts
Silver contacts undergo multiple cleaning and deoxidation treatments to remove surface oil stains and impurities, ensuring brazing compatibility. With customized positioning fixtures, silver contacts are accurately fixed at preset positions on stamped parts, with positioning deviation controlled within an extremely small range. This guarantees tight fitting between contacts and stamped parts, avoiding problems such as cold soldering, desoldering or poor contact caused by positioning deviation, and ensuring the precision of Silver Contact Fusion Welded Stamping.
Precise Temperature Control and Solidification in Silver-Based Brazing
Special silver-based brazing equipment is used for Stamped Part with Silver Contact Brazed, with automatic control of brazing temperature, holding time and cooling rate throughout the process to precisely match the brazing requirements of silver contacts and stamping base materials. Environmentally friendly brazing flux is evenly applied during brazing to remove oxide layers on welding surfaces and promote the flow and penetration of brazing filler metal, achieving atomic-level bonding between silver contacts and stamped parts. Natural cooling and solidification are carried out after welding to ensure no air holes, cracks or cold soldering at the welding joints.
Full-Process Segmented Inspection and Screening
A segmented inspection mechanism is implemented in the production process. After stamping, the dimensions and surface quality of stamped parts are inspected; after brazing, welding strength and quality are inspected; after surface treatment, treatment effect and cleanliness are inspected. Unqualified products are eliminated in each process. Comprehensive random inspections are conducted at the finished product stage, focusing on electrical conductivity, arc resistance and assembly adaptability, ensuring 100% of ex-factory Silver Contact Brazing on Metal Stamping meet customer requirements and industry standards, and guaranteeing stable quality of batch supply.
Application Fields
Electrical Contact Assembly for Contactor are suitable for various low and medium voltage circuit breakers including moulded case circuit breakers (MCCB), miniature circuit breakers (MCB) and residual current devices (RCD). As core components of moving and static contacts, they are responsible for circuit switching, overload protection and short-circuit protection. Featuring firm brazing, arc resistance and low contact resistance, these parts can withstand arc impact and mechanical stress caused by short-circuit current, eliminating hidden dangers such as contact falling off and poor welding, ensuring reliable operation of circuit breakers. They meet circuit protection requirements in industrial, civil and commercial scenarios, serving as a core guarantee for the safe operation of circuit breakers.
Silver Contact Assembly for Circuit Breaker are custom-designed for AC contactors and DC contactors, used as main and auxiliary contact components, mainly for start-stop control of motors and industrial equipment. High-purity silver contacts deliver excellent electrical conductivity and wear resistance. The brazed connection can endure frequent mechanical wear and arc impact from switching operations, effectively prolonging the service life of contactors and reducing equipment downtime and maintenance costs. They satisfy the differentiated needs of both high-power industrial equipment and small civil devices.
Silver Contact Stamped Part for Relay are widely applied in various switches such as push-button switches, travel switches, toggle switches and rocker switches, acting as core contact components to achieve precise circuit switching. Precision stamping technology ensures perfect matching of component dimensions with switch structures. Silver contacts feature reliable contact and burr-free surfaces, with firm brazing to prevent detachment. This guarantees switching accuracy while enhancing hand feel and service life, meeting switch assembly requirements in industrial control and civil electrical appliances.
Power Switch Silver Contact Assembly applies to various low and medium voltage electrical appliances including relays, fuses and disconnectors, undertaking core functions of circuit switching, control and protection. In response to the miniaturization and high-precision demands of relays, miniaturized precision stamping and brazing are realized. For the arc resistance requirements of fuses, silver contact materials and brazing processes are optimized to ensure components can withstand short-circuit current impact. They adapt to personalized performance requirements of different low and medium-voltage electrical appliances, supporting the stable operation of various electrical equipment.
