After years of expansion and upgrading, we have established two intelligent production bases in Haiyan and Vietnam with a total production area of 182,922 square meters, forming a coordinated global large-scale production network and delivering mature one-stop precision manufacturing services worldwide.

We operate a fully integrated in-house production system covering precision molds, high-speed stamping, precision injection molding, specialty plating and automated assembly. Our production equipment are premium models imported from Switzerland, Japan and other top international suppliers with industry-leading hardware configuration. Our stamping machines cover a wide tonnage range for high-speed production under diverse working conditions; precision injection molding machines with broad tonnage options support ultra-precision manufacturing of high-end connectors and precision structural components.

In core plating processes, we master coating technologies for copper, nickel, silver, gold, palladium-nickel and other composite coatings with stable and consistent performance. Adhering to green manufacturing principles, we have built independent and complete waste gas and wastewater treatment facilities, including advanced heavy-metal wastewater evaporation equipment to achieve zero discharge of nickel-containing wastewater, balancing high-efficiency production with environmental compliance.

We specialize in precision machining and are equipped with top-tier mold and fixture processing equipment capable of micron-level precision control. Our in-house R&D team of hundreds of engineers independently develops processes, custom molds, automated machinery and inline inspection systems. Supported by a full suite of high-precision testing equipment and a robust quality management system, we enforce strict quality control throughout all production stages to deliver products with superior accuracy and reliability.

Guided by the corporate spirit of Innovation, Integration, Pragmatism and Dedication, we stay committed to high-quality development. Going forward, we will continue to focus on precision interconnect and precision manufacturing, optimize our dual-base layout in China and overseas, upgrade core technologies and one-stop manufacturing capabilities, and strive to become a benchmark enterprise for high-end precision manufacturing with leading technology and reliable quality.
