Products Description
Stainless steel in-die riveting simultaneously completes stamping, bending, forming, and riveting within a multi-station progressive die, enabling the silver contacts and stainless steel substrate to form a high-strength mechanical bond during the forming stage. This eliminates instability caused by secondary welding or manual assembly. Leveraging the elasticity and corrosion resistance of SUS301/SUS304/SUS316 stainless steel strips, combined with the controllability of the micro-riveting structure, high cycle life, low contact resistance, and long-term dimensional stability can be achieved within a compact space.
In-depth Analysis of Technological Advantages
Superior Connection Strength and Reliability
The riveting points achieve mechanical interlocking through the plastic flow of stainless steel, resulting in a bond strength of ≥80 MPa, more than twice that of traditional soldering or spot welding. The connection interface is a pure metal-metal contact, free from inherent welding defects such as incomplete soldering and brittle intermetallic compounds for In-Die Electrical Riveting Contacts.
Excellent Electrical Performance
The riveting process avoids the additional resistance introduced by solder. A large-area, high-pressure contact is formed between the silver contacts and the stainless steel, resulting in a stable contact resistance of ≤50μΩ, approximately 20% lower than welding. In temperature rise testing, under the same current load, the Electrical In-Die Riveted Connections temperature rise can be controlled below 30K, improving current carrying capacity and safety.
High production efficiency and consistency
A single mold integrates stamping, forming, and riveting, reducing three intermediate processes: cleaning before welding, positioning, and cleaning after welding. Combined with 100% automated production, this increases the production cycle to hundreds of pieces per minute and pushes the yield rate to over 99.5%. The geometric dimensions and connection strength of each In-Die Rivet Electrical Contact are guaranteed by the physical dimensions of the mold, achieving batch consistency.
Application Areas and Value Realization
Industrial-grade universal transfer switches
Riveted Electrical Connection Components, as a core switching module, their high mechanical life (>1 million cycles) and stable low contact resistance ensure long-term trouble-free operation of production line control cabinets and motor drive centers.
Power distribution and energy management equipment
In-Die Rivet Electrical Contacts are used inside automatic transfer switches (ATS), disconnect switches, and smart meters, their high connection strength and corrosion resistance ensure absolute reliability of critical nodes in the power grid.
High-voltage control systems for new energy vehicles
Electrical In-Die Riveted Connections provide reliable connection solutions that withstand vibration, shock, and high/low temperature cycling in contactors and high-voltage distribution units within battery packs.
Packaging and Logistics Solutions
For large or special-sized In-Die Electrical Riveting Contacts, we employ a multi-layered protective packaging structure to ensure structural stability and surface quality during transportation: the inner layer uses customized pearl cotton cushioning, the middle layer is a thickened cardboard box for protection, and the outer layer is reinforced with a wooden or composite pallet, covered with a moisture-proof film and cable ties for overall reinforcement, effectively resisting vibration, moisture, and stacking impacts. Logistics methods can be flexibly selected according to project schedule, including express delivery, less-than-truckload (LTL), or full truckload (FTL) transportation. For bulk orders, sea or air freight options can be coordinated. Reinforcement inspection and labeling management are completed before shipment to ensure safe and timely delivery of Electrical In-Die Riveted Connections.
