What are Electrical Stamping Contact Components?
Electrical Stamping Contact Components combine a stamped metal substrate with a mechanically riveted silver contact to form an assembly-ready electrical contact part. The stamped base provides the mounting geometry and structural connection, while the silver contact forms the switching interface. The production route covers metal stamping, contact positioning, riveting, inspection, and finished-part packing, allowing appliance control switches, automotive electronic systems, medical instruments, and communication equipment manufacturers to receive pre-assembled contact components ready for downstream installation.
Riveting & Stamping Process Advantages of Silver Contact Riveted Assembly
Automated Precision Alignment for Stamped Bases
Tooling employs closed-loop progressive die designs that punch pilot holes, bend terminal tabs, and calibrate carrier flatness within a single stroke to maintain pitch repeatability across 100,000-piece production runs.
01
In-Line Quality Inspection for Stamping-Rivet Assembly
Optical vision systems scan 100% of manufactured contact rivets after cold-heading to verify crown concentricity, rivet head height, and absence of micro-cracks before surface passivation.
02
Interfacial Cold-Heading Solid Diffusion Bonding
Mechanical riveting combined with localized tonnage pressure forces micro-asperities of the silver alloy tip into the copper carrier matrix, preventing thermal separation under high-surge fault currents.
03
Stress-Relief Thermal Annealing Treatment
Stamped spring blades undergo controlled-atmosphere batch annealing at 450°C for 2 hours to eliminate residual internal bending stresses and stabilize long-term spring force deflection.
04
Typical Application Industries of Stamping Electrical Contacts
Household Appliance Controls
Integrated into high-load mechanical thermostats, washing machine door interlock switches, and compressor start relays requiring low contact temperature rise under 16A/250VAC resistive loads.
Automotive Electronic Systems
Deployed in 12V/24V automotive seat-adjuster switches, blower motor control boards, and horn switching modules subject to constant vibration and bridge-circuit arcing.
Medical Instrument & Communication Equipment
Installed in diagnostic equipment power distribution units and signal relay actuation modules where low millivolt drop and zero-oxidation contact integrity are mandatory.
Packing & Delivery of Electrical Stamping Contact for Relay
Finished-Part Protection
Completed Riveted Electrical Connection Components should be packed to prevent bending, contact deformation, contamination, and surface damage during handling.
Lot Identification
Each production lot can be identified according to the customer part number, order reference, or drawing revision to support incoming inspection and inventory control.
Bulk Shipment
Production quantities can be packed in protective inner packaging and outer cartons according to component geometry, order quantity, and transportation requirements.
Assembly-Ready Delivery
The shipment is supplied as a completed stamped metal base with the silver contact already riveted, allowing the customer's production line to proceed directly to the applicable installation operation.
