Hydraulic Rod Coating Equipment

Coating Equipment for Hydraulic Rods

In the hydraulic rod industry, thermal spray technology has become the inevitable trend to replace hard chrome plating. There are three main types of hydraulic rods: those used in construction machinery, hoisting machines, and coal mining machines. Each type faces unique challenges due to its specific operating conditions, requiring different thermal spray processes.

For construction machinery hydraulic rods, United Coating employs a wear-resistant spraying process followed by post-spray grinding and polishing.

For hoisting machine hydraulic rods, traditional spraying involves moving the spray gun along the rod. However, these rods can be very long, and after the spray gun travels a certain distance, spraying parameters tend to shift, causing uneven coating quality. Moreover, housing a nearly 15-meter-long spraying mechanism inside a spray booth is costly and compromises dust collection efficiency. United Coating’s solution fixes the spray gun in place while the hydraulic rod moves through. The spray booth only covers the spray gun area, which eliminates parameter drift caused by long-distance movement, reduces spray booth construction costs, and significantly improves dust removal—a perfect win-win solution.

Coal mining machine hydraulic rods are produced in large quantities and operate under harsh and complex conditions. Due to limited budgets in coal mines and enterprises, high-consumption and costly thermal spray methods like supersonic flame spraying are not feasible. There is urgent demand for cost-effective, high-performance surface treatment solutions suitable for continuous operation. Beijing United Coating Technology Co., Ltd. has pioneered innovative spraying technologies combined with clever automation designs, providing new options for thermal spray treatment of coal mining hydraulic rods. These solutions offer much lower costs than supersonic flame spraying and laser cladding while achieving higher efficiency.

Additionally, if copper plating or deposition on coal mining hydraulic rods is required, United Coating’s latest technology can rapidly deposit multiple metals such as copper, iron, and even alloy coatings.
