Products Description
Copper with Silver Plating is a key conductive and structural component made from high-purity electrical-grade copper using high-speed precision molding. It is widely used in electrical components such as relays, switches, contactors, and fuses. This type of product is renowned for its stable conductivity, excellent ductility, and highly consistent geometric precision. It can operate for extended periods under conditions of frequent switching, current fluctuations, and complex assembly, making it a crucial foundational component for reliable connection and safe operation in new energy systems, power control equipment, and industrial automation.
Mold System and Core Technology Features
Mold Steel Selection
Key mold components for Precision Copper Stamped Parts utilize high-hardness, wear-resistant alloy steels such as SKD11 and DC53, significantly extending mold life and meeting the demands of long-term mass production.
01
Vacuum Heat Treatment Process
Punches and cavities are treated to achieve a hardness of HRC 60–62, effectively reducing wear and dimensional drift risks for Copper Stamping Electrical Precision Parts.
02
High-Precision Guiding System
Ball bearing guides and guide sleeves ensure alignment accuracy of the upper and lower molds ≤0.01 mm for High Precision Progressive Stamping Copper Parts.
03
Ultra-Precision Machining Capability
Wire EDM accuracy ±0.005 mm, combined with mirror EDM, achieves a cavity surface roughness Ra ≤0.4 μm.
04
Technical Advantages
Exceptional Reliability
Strict control at every stage, from material consistency and dimensional accuracy to surface treatment, ensures stable performance of stamped copper sheets under vibration, temperature cycling, and long-term loads, directly extending the lifespan of end products..
Optimized Thermal Management
The high thermal conductivity of copper, combined with our customizable structures that increase heat dissipation area (such as heat sinks), effectively dissipates heat from contacts, preventing thermal runaway for Precision Copper Stamped Parts.
Design Freedom and Integration
Strong capabilities in producing complex parts allow for the integration of multiple functions into a single Copper Stamping Electrical Precision Parts, reducing component count, simplifying assembly, improving overall system reliability, and lowering costs.
