Copper Stamping Die
Products Description
In fields such as low-voltage electrical appliances, new energy vehicle connectors, and industrial control switches, copper stamping die and silver contact riveted switches are core components for current conduction and signal transmission. Their quality directly depends on the precision of the production mold-a deviation in the riveting force of a single silver contact or an angular error in a copper bend can lead to poor contact, shortened lifespan, or even safety hazards. We specialize in developing molds for copper stamping components and silver contact riveted switches, focusing on "material property adaptation + process precision control," providing professional buyers and engineering clients with a complete mold solution "from drawings to mass production." It is not only a production tool but also a process enabler that transforms "design requirements" into "stable quality."

Engineering Applications: Ensuring Switch Performance at its Core
High-end Relay Manufacturing
In automated control systems, switch reliability directly impacts system stability. Our dies ensure contact geometry precision, maintaining low contact resistance in relays through millions of operations and preventing signal distortion caused by contact deformation.
01
Industrial Control Switches
For switches operating in high-vibration environments, contact connection reliability is critical. Optimised riveting strength from our dies ensures stable contact connections during long-term vibration, significantly reducing equipment failure rates.
02
Medical Equipment Switches
In medical equipment, the electrical performance of switches directly affects equipment safety. Die-manufactured contact assemblies ensure burr-free, high-purity surfaces, meeting medical-grade electrical safety standards.
03
Smart Grid Equipment
In high-precision switch applications, die-controlled contact consistency ensures stable switch performance during frequent operations, providing a fundamental guarantee for the reliable operation of smart grid equipment.

The Engineering Philosophy of Material Synergy – A Performance Leap of 1+1 > 2
1. Copper Stamped Skeleton: The Perfect Carrier of High-Efficiency Conductivity and Structural Strength
The Cornerstone of Ultimate Conductivity: We select high-conductivity copper of T2 grade and above. Its near-zero oxidation and conductivity second only to silver ensure the lowest impedance and energy loss along the current transmission path from the inductor to the contact point. This directly translates to lower component temperature rise and higher energy efficiency.
Balance between Structural Rigidity and Economy: Cold-rolled copper strip possesses excellent ductility and strength. Through precision stamping, it can be formed into complex three-dimensional structures, serving as both a conductive bridge and a supporting skeleton, achieving integration of function and structure, optimising overall cost while ensuring performance.
2. Silver Contacts: The "Special Forces" that Win at the Moment of Disconnection
Weldability and Low Contact Resistance: Pure silver or silver alloy contacts provide an extremely stable and low-resistance contact surface at the moment of energisation. Its excellent weldability ensures that the contacts will not melt and stick together due to instantaneous high temperature under high current impact, thus eliminating the "sticking" fault of the switch.
Superior resistance to arc erosion: The arc generated when the switch breaks is the number one killer of contact materials. Silver can withstand extremely high arc temperatures, and its evaporation and sputtering rates are controlled at extremely low levels, thereby greatly extending the electrical life of the component and ensuring the stability of the contact resistance of the switch within its rated lifespan.
3. Synergistic effect of materials
Our solution cleverly leverages the greatest advantages of both materials: allowing copper sheet metal to undertake the task of "high-flow conduction," while allowing the silver contacts to focus on the demanding challenge of "critical point contact and breaking." This division of labour achieves an optimal configuration of performance and cost, a level that cannot be achieved by a single material.
