Gold-Plated Dome

Professional Gold Plating

Why Gold Plating?

For applications with extreme requirements for electrical connections, gold-plated domes provide crucial performance assurance. Although stainless steel itself has some oxidation resistance, the chromium oxide layer formed on its surface can affect conductive stability. Compared to conventional treatments like nickel plating, professional gold plating not only completely prevents base material oxidation but also endows the dome surface with excellent and long-lasting conductive performance. This superior conductivity and protection, combined with high-quality dome base material, is vital for high-specification products requiring extreme reliability and long-term stable operation, ensuring flawless signal transmission.

Professional Gold Plating Process Detail

What Makes it Professional?

Professional gold plating goes far beyond material selection; it is reflected in a deep understanding and precise control of complex metallurgical issues. For example, to address the hydrogen embrittlement phenomenon that stainless steel is prone to during traditional electroplating processes—which leads to reduced plating adhesion and compromised material toughness, significantly shortening product lifespan—advanced gold plating technology that circumvents hydrogen embrittlement risks is employed. This ultimate pursuit of process details ensures a dense, uniform, and firmly adhered plating layer, fundamentally guaranteeing the dome's high reliability and ultra-long mechanical life, meeting the most stringent application standards.

Medical Grade Quality

The manufacturing process strictly adheres to medical-grade standards, utilizing top-tier precision molds, industry-leading advanced equipment, and meticulous production processes to ensure each finished dome achieves a high degree of stability. Supported by a comprehensive and detailed quality management system, the product aims for near-zero defect functional performance. It is this ultimate pursuit of quality that has earned the long-term trust and firm choice of many renowned medical device companies.
