Products Description
Electrical Contact Stamping is a process that shapes metal materials into electrical contacts of specific forms via stamping die technology. This process uses high-precision and high-speed stamping equipment to press metal sheets into contact points with electrical conduction performance. As high-precision connecting components, electrical contacts are required to not only have excellent electrical conductivity but also withstand severe environmental conditions such as long-term current load, friction, and temperature variation, so as to ensure the stable operation of equipment.
The Electrical Rivet Connection Solutions products we provide are widely applied in various fields, including power connections, switches, relays, battery contact points, and electronic plugs. Through precise die design and refined stamping technology, the dimensions, shapes, precision, and surface treatment of our products can all be customized according to customers' requirements.
Product Advantages
With a high-purity silver and copper substrate combined with silver-plated surface treatment, the contact resistance is stably maintained at the microohm level, ensuring lossless transmission of current and signals and avoiding heat generation and signal attenuation caused by excessively high resistance. In high-frequency signal transmission scenarios, the signal loss rate of Embedded Riveted Electrical Contacts is far lower than that of traditional copper contacts, which is suitable for high-speed transmission requirements such as 5G communication and industrial Ethernet.
Through the precision stamping process and aging strengthening treatment, the elastic fatigue life of the contact shrapnel of In-Die Riveted Silver Contacts can reach more than one million times. It can maintain a stable shape and elasticity under long-term high-frequency opening and closing impacts, and no poor contact will be caused by elastic fatigue. For high-power scenarios, tungsten-copper alloy material is adopted, which has excellent arc erosion resistance, can withstand the arc impact during high-current on-off, and extends the service life of the equipment.
Copper Stamped for Switch adopts a high-speed precision stamping process, which can process micro contact structures with a thickness of 0.03mm-1.0mm, and the dimensional tolerance is controlled at the micron level, adapting to the miniaturization and lightweight installation requirements of modern electronic equipment. At the same time, it supports the customization of special-shaped structures, adapts to complex magnetic circuits and installation spaces, and can directly improve assembly efficiency without requiring customers to carry out a major transformation of equipment.
The surface coating of Copper Stamping for Switch adopts silver plating, gold plating, or tin plating processes, providing strong adhesion and resistance to corrosion in complex environments such as humidity and salt spray, and maintaining stable performance in scenarios such as outdoor communication base stations and new energy vehicles. Some products adopt a sealed structural design to further improve resistance to dust and oil pollution, meeting the long-term operation requirements of extreme working conditions.
Production Process
Screening and Pretreatment of High-Purity Raw Materials: Copper Stamping for Switch strictly adopts high-purity metal sheets such as silver and copper that comply with the ASTM B265 standard. After being delivered to the factory, the purity and impurity content are verified by spectral analysis to ensure the consistency of electrical conductivity. The surface of raw materials is degreased and leveled to remove rolling oil and oxide layer, laying a foundation for subsequent stamping forming.
High-Speed Precision Stamping Forming: Copper Contact Riveting uses imported high-speed precision punch presses combined with precision molds to process precious metal sheets into micro-structures such as shrapnels and bonding pads, with a stamping speed of up to 1200 strokes per minute, ensuring production efficiency and dimensional accuracy. In view of the work hardening characteristics of precious metals, a segmented stamping and intermediate annealing process is adopted to reduce the single deformation and avoid cracks and stress concentration.
Surface Coating Strengthening Treatment: Silver plating, gold plating, or tin plating processes are selected according to scenario requirements, and vacuum electroplating or barrel plating methods are adopted to ensure uniform coating thickness and strong adhesion, which not only improves electrical conductivity but also avoids cost waste caused by excessive coating thickness. Gold plating further enhances the corrosion resistance and signal stability of In-Die Riveting for high-reliability scenarios.
Whole-Process Inspection and Screening: A multi-dimensional inspection system is established to realize whole-process inspection from raw material warehousing to finished product delivery. The material purity and composition are inspected at the raw material stage; the stamping dimensional accuracy and coating adhesion are inspected during the production process; the contact resistance test, elastic fatigue test, and salt spray corrosion test are carried out at the finished product stage, ensuring that the performance of each piece of In-Die Staking complies with international standards. Defective products are directly rejected, with the yield rate reaching 99.7%.
