Project Introduction: Full‑Automatic Silver‑Contact Welder

Sep 11,2026

Silver contacts are core conductive components for low‑voltage electrical apparatuses. Silver‑contact workpieces are small‑sized, and dissimilar‑metal welding brings high technical difficulty. Conventional welding mostly relies on manual loading‑unloading, positioning and sorting. Manual operation tends to produce deviations, frequently resulting in cold joints, offset welding, silver‑contact deformation and uneven fusion.

The Haifei full‑automatic silver‑contact welder is developed for automatic‑production working conditions of silver contacts. It realizes automatic loading, automatic welding, automatic inspection and automatic unloading.

I Customer Background and Pain Points

One customer focuses on production and supporting services of various silver‑contacts and switch conductive assemblies for low‑voltage electrical apparatuses. Its products are widely applied in the low‑voltage electrical‑apparatus industry.

Production pain points of the original welding process:

1.Manual loading‑unloading and positioning have limited accuracy. Contact offset, welding dislocation and surface deformation easily occur, causing switch jamming during make‑and‑break and unstable contact.

2.Uneven heat‑input control in manual welding leads to inconsistent weld‑spot penetration depth, readily generating defects such as cold joints and weak welds.

3.Limited welding efficiency, continuously rising labor cost. No records for equipment process parameters and production data.

II Customer Requirements

1.Realize automatic loading, welding, inspection and unloading.

2.Control welding pressure and heat output to reduce contact crushing, burning and deformation.

3.Enable long‑time continuous stable equipment operation with steady parameters. Production data shall be storable and traceable to adapt to automatic production.

III Custom‑Developed Solutions

Targeting customer requirements, the dedicated R&D team repeatedly tuned and optimized schemes in view of drawbacks of manual silver‑contact welding such as poor accuracy and low efficiency, to ensure deliverables fit customer demands. Details are as follows:

1.Process verification: Conduct multiple groups of full‑automatic welding process tests for silver contacts of different specifications. Repeatedly optimize parameters including automatic feeding rhythm, positioning accuracy and welding pressure.

2.Equipment selection: Adopt Haifei full‑automatic silver‑contact welder. Integrated all‑in‑one automatic production line realizes automatic loading, automatic welding, automatic inspection and automatic unloading. Heat input is concentrated and welding pressure application is stable. Contacts resist deformation and burning. Weld spots are full, uniform, firmly bonded and deliver stable electric conduction.

3.Structural design: The complete machine adopts automatic structure with smooth operation and stable long‑term welding performance. Custom‑built exclusive positioning tooling for contacts effectively mitigates positioning offset and welding deviation, guaranteeing regular and uniform welding quality.

4.Core Advantages

Automation: labor‑saving, high efficiency.

Stable quality: uniform weld spots, reliable performance.

Full‑range control: traceable data, easy quality control.

IV Delivery, After‑Sales Service and Customer Feedback

Pre‑acceptance and equipment inspection were carried out. Continuous trial operation maintains stable welding pass rate. After commissioning, all original welding‑related production pain points of the customer are fully resolved. Timely, professional and thoughtful after‑sales service earns positive customer comments.
