Electroplating Workshop

A large electroplating facility in China spans approximately 80,000 square meters and is equipped with 12 fully automatic overhead traveling crane (OTC) electroplating production lines, serving the surface treatment needs of automotive parts, electronic components, hardware products, and other industries. The workshop maintains a relative humidity of 70%–95% year-round, with high concentrations of chemical vapors (sulfuric acid mist, hydrochloric acid mist, chromic acid mist, hydrogen cyanide). Temperatures in the tank-side areas can reach 45°C–55°C.

Currently, each production line is equipped with program-controlled hoists (overhead cranes) that automatically transfer workpieces between plating tanks with positioning accuracy of ±5mm. Each tank is equipped with 20–30 PLC controllers, online sensors (pH meters, concentration meters, temperature probes), and industrial cameras, which precisely control key process parameters such as current density, bath temperature and composition, and plating time. Production data is integrated through the MES system, enabling full-process digital management and control. However, wired network deployment is costly and difficult to maintain. The acidic alkaline fumes and high-humidity environment in the workshop directly corrode cable sheaths and equipment interfaces, resulting in an average service life of less than 6 months for standard networking equipment. At the same time, strong electromagnetic interference generated by rectifiers causes communication lag and packet loss, affecting the coordinated control of hoists and production line equipment.

The customer urgently needs an industrial wireless communication network with high corrosion resistance, high reliability, and long service life to ensure stable data transmission and seamless equipment connectivity.
