The silver-copper composite rivet machine is a precision forming device specially designed for manufacturing electrical contact parts. It integrates precision rolling, automatic feeding, thickness control, and tension adjustment to produce high-quality flat silver-copper composite strips for switches, relays, and contactors.

Working Principle

The machine adopts a precision double-roller rolling system. Silver-copper composite raw materials are continuously and stably fed into the high-precision rolling zone through a servo-driven feeding mechanism. Under set pressure and speed, the rollers press the composite material to a target thickness with high uniformity. The equipment uses digital thickness detection and real-time compensation control to ensure dimensional accuracy. It also releases internal stress in the material during flattening, keeping the flat strip straight, free of warping, and with tight bonding between the silver layer and copper base. After flattening, the material is automatically collected neatly, realizing continuous, stable, and high-efficiency production.

Key Advantages

High Bonding Strength: Ensures tight combination of silver and copper layers, no delamination, blistering, or cracking during use, greatly improving switch reliability and service life.

Ultra-High Dimensional Precision: Stable thickness control with extremely low tolerance, ensuring consistent size of contact parts and smooth assembly.

Excellent Surface Quality: Produces smooth, flat, and scratch-free surfaces, enhancing electrical conductivity, contact stability, and oxidation resistance.

Stress Relief & High Flatness: Effectively eliminates internal stress, so finished strips do not deform or warp, meeting strict assembly requirements of electrical switches.

High Efficiency & Energy Saving: Supports continuous automatic production, reducing material waste and labor costs, suitable for large-scale manufacturing.

Strong Adaptability: Compatible with various specifications of silver-copper composite materials, adjustable for different thickness and width requirements of switch contacts.

This machine provides core processing support for high-performance electrical switch contacts, helping manufacturers improve product quality, stability, and market competitiveness.
