Project Location: China
Project Background:
Mining machinery components operate under extremely harsh conditions, including heavy wear, abrasive materials, and exposure to moisture and chemicals. A leading Chinese mining equipment manufacturer approached ZHYAO to supply a fully automated powder coating line capable of providing durable, corrosion-resistant, and uniform coatings for large-scale mechanical parts such as excavator buckets, crusher frames, and conveyor components. The goal was to enhance component longevity, reduce maintenance frequency, and improve overall production efficiency.
