Key Features of In‑Mold Riveting Process of Riveted Assembly
Simultaneous Stamping and Riveting Integration
The progressive die tooling combines high-speed precision stamping with in-mold automatic riveting, feeding silver alloy contact tips directly into the C17200 spring leaf during the metal forming sequence.
01
Interlocking Mechanical Joint Integrity
Cold-forming pressure creates an interference fit between the rivet shank and the pre-pierced carrier hole, achieving high shear strength without thermal distortion or micro-cracking in the heat-treated copper substrate.
02
Dimensional Repeatability in High-Volume Runs
Automated optical inspection systems monitor feed pitch and rivet head concentricity in real time, guaranteeing that every stamped batch maintains identical micro-gap kinematics for sensitive circuit breakers.
03
Optimized Grain Flow and Residual Stress Control
Tooling geometry is engineered to preserve the natural grain structure of precipitation-hardened copper alloys, preventing micro-fracturing along bend radii during repetitive high-speed actuation.
04
Customization Options of Relay Moving Spring Assembly with Armature
Alternative Alloy Substrate Selection
Engineers can specify alternative spring materials such as phosphor bronze (C5191) or nickel-silver based on specific cost targets, spring rates, and operating temperatures.
Custom Contact Material Overlays
Contact tips can be swapped from standard AgNi to AgSnO2, AgCdO, or bimetallic silver-copper compositions depending on the inductive or capacitive load profile.
Tailored Plating Specifications
Choose from selective silver plating on the contact zone only, full electroplated tin, or gold flash options to meet specialized PCB soldering or socket insertion requirements.
Prototyping and Progressive Die Tooling
Our in-house toolroom designs custom progressive dies using wire EDM and CNC machining, allowing rapid sample turnaround for new product development programs.
