Business Areas

• Surface treatment (plating) for electronic and communication components: We perform surface treatment for various electronic components such as C-Type USB connectors for smartphones, ultra-precision pogo pins, FPC, and HDMI. We achieve excellent wear and corrosion resistance through Reel-to-Reel automatic plating lines and spot plating technology.
• Surface treatment for automotive electronics and secondary battery components: We perform functional surface treatment for electric vehicle battery components, automotive connectors, and sensor terminals. We apply customized alloy plating specifications to ensure stable electrical conductivity and durability even in harsh operating environments.
• Harness assembly and component processing: Based on plated terminals and metal processed products, we perform wire harness assembly and post-processing of related parts. We enhance the perfection of product quality through a production system linked from surface treatment to assembly.

Products

• Connector terminal plating for smartphones and IT devices: These are high-functional surface-treated products that prevent wear and corrosion even with repeated insertion/extraction and exposure to external environments. They are manufactured through special alloy plating processes such as Rhodium-Ruthenium and Palladium-Nickel.
• Charging terminals (Pogo Pins) for wireless earphones and wearables: These are charging components for wireless devices that reduce allergies when in contact with human skin and have corrosion resistance against sweat and moisture. High-precision surface treatment technology ensures a uniform film and high reliability.
• Plated terminal components for electric vehicle batteries: These are high-current compatible plated components applied to automotive battery modules and wiring systems. They provide stable electrical conductivity and insulation reliability even under high-temperature and high-voltage conditions.

Special Notes

• Ultra-precision Reel-to-Reel automation and selective plating technology: Through micrometer-level precision spot plating technology and continuous automated lines, we achieve both cost reduction and quality uniformity. We maximize the durability of core contact points while reducing unnecessary consumption of precious metals.
• References applied to major domestic and international flagship devices: We are in charge of plating core charging terminals for large-scale global mass-produced products such as Samsung Electronics' Galaxy smartphones and Galaxy Buds, and our global-level mass production capabilities and quality management systems have been verified.
• Establishment of eco-friendly wastewater recycling facilities: We operate eco-friendly water treatment facilities that purify a significant portion of the wastewater generated during the plating process for reuse in the process, proactively responding to environmental regulations.
