On March 3, 2026, an invention patent titled "An In-Mold Welding Device for Silver Contacts" was officially granted (Patent No.: CN117139928B). Focused on the manufacturing of conductive contact products, this technology achieves direct welding of silver contacts after they are fed to the lower welding assembly via a conveying track, through the collaborative design of a contact feeding module, a welding module and a driving module. It can significantly improve production efficiency, reduce manufacturing costs, effectively enhance welding quality, and provide new technical support for the large-scale, high-precision production of Brazed Silver Contact Stamped Parts.
As a key process in silver contact production, the core value of in-mold welding technology lies in the high integration of contact feeding and welding procedures, eliminating precision loss and efficiency bottlenecks caused by multi-station transfer in traditional processes. In practical applications, the device enables accurate positioning and stable welding of contacts, greatly reducing manual intervention and defective rates, while shortening production cycles. It meets the requirements for large-scale, high-precision manufacturing of conductive contacts, and is particularly significant for improving the production efficiency and quality of Silver Contact Brazed on Stamped Part.
With the rapid development of power equipment, new energy vehicles, industrial automation and other fields, higher requirements have been put forward for the performance, consistency and delivery efficiency of silver contacts and supporting brazed parts. Under the traditional production mode, the welding of contacts and contact bridges mostly relies on manual or semi-automatic equipment, which is prone to problems such as insufficient welding strength, fluctuating contact resistance and poor batch consistency. These issues make it difficult to meet the stringent standards of high-end equipment for core components, and also restrict the quality upgrading of Brazed Silver Contact Stamped Parts.
Against this technological trend, Xiamen Apollo Electric Co., Ltd. has deeply rooted itself in the field of Silver Contact Resistance Welded Stamping. Relying on mature process accumulation and technological innovation, the company provides the industry with highly reliable core supporting products. Focusing on core products such as silver contact spot-welded components and stamped part brazed components, the company adopts advanced welding technology and precision machining, and strictly controls contact positioning accuracy, welding penetration and contact resistance stability, making its products suitable for various application scenarios including high-frequency on-off, high-current load and complex working conditions.
To meet the industry's demand for efficient and high-quality production, Xiamen Amber Electric Co., Ltd. has deeply integrated advanced concepts such as in-mold welding into product R&D and manufacturing, optimizing product structure design and process control:
- For silver contact products, high-purity silver-based materials and precision stamping processes are adopted to ensure dimensional accuracy and electrical conductivity.
- For Stamped Part with Silver Contact Brazed, precise welding parameter control and full-process inspection are implemented to improve bonding strength and batch consistency, effectively reducing contact resistance and failure rates.
At present, the Brazed Silver Contact Stamped Parts produced by Xiamen Apollo Electric Co., Ltd. have been widely used in core equipment such as low-voltage electrical switches, relays, contactors and circuit breakers, providing stable and efficient supporting solutions for complete equipment manufacturers. With the popularization of key technologies such as in-mold welding, the company will continue to deepen process innovation, optimize product performance, help improve the quality and efficiency of core component manufacturing in the industry, and provide solid support for the high-quality development of power equipment, new energy and other sectors.
