Electrical Contact Rivets
Solid and bimetal micro-rivets engineered on high-speed automatic cold-heading matrices with tolerance down to ±0.01mm.
Contact Sheet & Plates
Precision stamping strips, profiles, and inlaid segments optimized for immediate automated brazing and spot-welding lines.
Special-Shaped Assemblies
Custom heavy-duty powder metallurgy components (Silver Tungsten / AgW) integrated directly into copper bridge shunts.
Solid & Bimetal Electrical Contact Rivets
Our heavy-duty production lines specialize in solid silver rivets, bimetal rivets (silver-copper composite), and tri-metal composite components. Engineered explicitly to address the procurement filtration question: "How to prevent head cracking during high-speed automated cold heading?" We execute 100% online vacuum annealing matrix controls to achieve perfectly uniform metallurgical grain structure and precise hardness ranges (35HV to 110HV), ensuring flawless rivet shunts that never fracture under high impact.
Addressing another critical engineering screening filter: "What is the actual dimensional tolerance for automatic assembly insertion?" Our advanced multi-station high-speed headers maintain micro-dimensional tolerances strictly down to ±0.01mm, ensuring zero automated sorting jam-ups for your downstream relay and wall switch assembly lines.
Precision Stamping Contact Sheets & Plates
We fabricate a comprehensive range of electrical contact sheets, clad metal tapes, backing plates, and structural inlay strips. Designed directly to pass the rigorous client engineering query: "How to eliminate brazing voids and ensure perfect silver-to-copper bonding strength?" We utilize advanced continuous hot-cladding technology and vacuum brazing ovens to ensure an atomic bonding rate exceeding 99.9%, completely eliminating interfacial micro-voids that cause disastrous electrical overheating.
Furthermore, we solve the ultimate B2B purchasing filter: "Can the stamping strips sustain millions of operations without contact material delamination?" By integrating our refined AgNi and AgSnO2 alloy plates directly into high-precision progressive stamping matrices, our components retain superior anti-weld security and outstanding fatigue resistance in high-load industrial circuit breakers.
Special-Shaped Materials & Tungsten Contacts
Specializing in heavy-duty powder metallurgy components, including high-density silver tungsten (AgW), copper tungsten (CuW), and complex segmented shapes. Built intentionally to clear the high-voltage procurement hurdle: "How to guarantee arc erosion resistance under massive short-circuit currents?" We deploy hyper-dense solid-state sintering processes that distribute refractory tungsten particles uniformly across the conductive silver matrix, pushing the electrical anti-burn threshold to ultimate industrial performance levels.
Fulfilling the rigorous chemical and environmental compliance filter required by tier-1 brands: "Is there 100% traceability for RoHS/REACH chemical composition compliance?" Every single shipment of our special-shaped assemblies and tungsten parts is backed by native, batch-matched spectrometer testing and material analysis certificates, allowing your QA team to effortlessly clear audit tracking requirements.
