Key Value Propositions
High Precision
Utilizing advanced numerical control progressive die technology, dimensional accuracy is controlled within ±0.02mm, 50% higher than traditional stamping methods. This precision meets the requirements of high-precision scenarios such as 5G communication.
Material Adaptability
Supports more than 10 types of copper alloys, including pure copper (Cu≥99.9%), brass (Cu65% - Cu85%), and phosphor bronze. The electrical conductivity ranges from 85% - 100% IACS, ensuring suitability for different electrical and mechanical applications.
Cost-effective Production
Seamless transition from sample to mass production, with a die life of over 1 million times, reducing the manufacturing cost per batch by 30%. This makes it an economically viable option for both small-scale and large-scale orders.
Material Science Advantages
Purity Control
Through electrolytic refining processes, the impurity content of copper materials is kept below 0.1%. This high purity ensures the hardness and corrosion resistance of the final products, making them durable in various environments.
01
Alloy Enhancement
Optionally adding trace elements such as tin and zinc can significantly enhance the toughness and wear resistance of copper. These alloyed copper materials perform better under mechanical stress and friction.
02
Surface Treatment
Protective coatings such as nickel plating and gold plating not only extend the service life of the products but also improve their visual appeal. They protect the copper from oxidation and other forms of surface damage.
03
Material Properties
Copper's excellent ductility makes it ideal for intricate pattern carving and complex forming processes without significant deformation, ensuring the integrity of the design.
04
Advanced Manufacturing Processes
Die Design
Employing 3D reverse modeling and CAE simulation, potential stamping risks such as cracking and wrinkling can be predicted and evaluated in advance. Hard alloy dies (YG15 material) are used, which can withstand high temperatures of up to 300℃ and have a wear amount of ≤5μm per 100,000 operations, ensuring long-term stable production.
Forming Technology
Multi-station progressive die technology enables integrated processes of punching, bending, and drawing, reducing secondary processing by 90%. Micro-stamping technology can achieve a minimum feature size of 0.2mm, suitable for manufacturing miniature electronic Copper stamping parts.
Surface Finishing
A variety of electroplating processes are available, including gold plating (0.1 - 5μm), nickel plating (5 - 15μm), and tin plating (10 - 20μm). Electroless nickel plating can pass a salt spray test of more than 1000 hours, making the products suitable for marine-climate environments.
Typical Industry Applications
Connectors
Copper Stamping and Copper Sheet Stamping are used to produce phosphor bronze terminals, which can withstand more than 5000 insertions and extractions, with a contact resistance of ≤10mΩ. These terminals ensure stable electrical connections in electronic devices.
Heat Sinks
0.3mm ultra-thin pure copper stamping parts with optimized micro-channel designs can reduce the temperature of chips by 15℃, improving the performance and lifespan of electronic components.
Circuit Breakers
Custom Copper Stamping parts with silver - plating can withstand a short-circuit current of 10kA and have a temperature rise of ≤60K, complying with IEC 60947 standards. They play a crucial role in the safety and reliability of electrical systems.
Relays
Copper stamping parts, after stress-relieving annealing, can resist vibrations of 20g (tested according to IEC 60068 - 2 - 6), ensuring no failure after 100,000 on-off operations.
