What is the Armature Beryllium Copper Riveting Assembly?
Designed specifically for high-frequency switching architecture, the precision-engineered Armature Beryllium Copper Riveting Assembly serves as the critical current-carrying and mechanical actuation bridge inside automotive and industrial power relays. Combining superior spring memory of copper alloy with optimized contact tip riveting, this component maintains stable circuit continuity under severe thermal and mechanical shock conditions. Operating as a direct factory source based in China, advanced progressive stamping and cold-heading integration workflows deliver consistent mechanical tolerances and bulk production capacity for global relay and low-voltage switchgear OEMs.
Integrated Stamping & Riveting Workflow of Electrical Contact Assemblies
Precision Coil Slitting & Feeding
Raw C17200 beryllium copper strip stock is precision-slit to exact width tolerances and fed into high-speed mechanical presses equipped with optical sensor error detection.
Progressive Die Stamping
Multi-station progressive dies form complex carrier profiles, bending radii, and pilot holes in a single stroke to maximize structural rigidity and reduce residual stress.
In-Die Mechanical Riveting
Pre-formed solid or bimetal contact tips are automatically fed and cold-headed directly into the stamped carrier aperture, guaranteeing high push-out strength without thermal distortion.
Precipitation Hardening Heat Treatment
Grinding is the most common process in sprocket surface treatment, which can remove burrs on the sprocket surface and improve its surface finish and flatness.
Typical End-use Applications of In-Mold Riveting Components
Automotive Power Relays
Handles continuous high-current loads in 12V/24V vehicle distribution modules and HVAC switching circuits without thermal degradation.
Smart Meter Latching Relays
Provides precise actuation and stable low-resistance paths required for high-accuracy residential and industrial smart power metering systems.
Industrial Control Contactors
Integrates seamlessly into motor starter contact blocks, enduring repeated high-load mechanical impacts and electrical arcs.
HVAC Circuit Protection Devices
Maintains reliable spring tension and arc-withstanding performance in residential and commercial air conditioning compressor control units.
Frequently Asked Questions about In-Die Rivet Electrical Contacts
Can you produce In-Die Rivet Electrical Contacts according to the customer's stamping drawings?
+
-
Yes. We accept OEM and ODM production based on your detailed 2D/3D CAD drawings, covering custom stamping profiles, precise rivet locations, and specific surface plating configurations.
Do you support small-batch prototype samples before mass production?
+
-
Yes. Prototype samples are fully supported for functional verification and lab testing. Please provide drawing documentation for sample cost evaluation and quick lead-time setup.
What inspection reports can you provide for mass-production batches?
+
-
We supply comprehensive batch inspection records covering exact dimensions, riveting push-out strength, material composition certificates, and plating thickness test data upon request.
How do you prevent oxidation on beryllium copper spring parts during transit?
+
-
Components are passivated, treated with anti-corrosion inhibitors, and vacuum-sealed in moisture-barrier bags with desiccants inside reinforced export-grade cartons.
How does integrated riveting improve relay contact performance?
+
-
Cold-headed mechanical riveting creates an intimate metallurgical and mechanical bond that eliminates contact resistance spikes and prevents tip detachment under high shock loads.
