The company is responsible for manufacturing structural components for high-strength hydraulic supports used in coal mines. Although traditional spray painting processes are widely used, they face significant challenges in terms of environmental compliance and coating corrosion resistance. Our powder coating line for structural components is designed to address the characteristics of coal mining machinery—large size, complex shapes, and extremely high corrosion resistance requirements—by utilizing industry-leading electrostatic powder coating technology. Compared to traditional liquid paint, powder coating offers significant advantages, including being solvent-free and emitting zero VOCs (volatile organic compounds), which aligns perfectly with the national “Dual Carbon” strategy and environmental protection policies.
