Hebei, China – February 2026 – ZHYAO, a leading manufacturer of automated powder coating equipment, has successfully implemented a new solution designed to achieve uniform powder coating on small metal hardware parts, including brackets, hinges, and fasteners. The innovative approach addresses common challenges in high-volume production, ensuring improved coating consistency, reduced material waste, and enhanced product quality.
Addressing Industry Challenges
Small metal hardware parts often present difficulties during powder coating due to their intricate shapes, grooves, and sharp edges. These features can create “shadow areas” that prevent uniform powder deposition. Additionally, variations in electrostatic charge distribution and minor differences between production batches frequently result in inconsistent coating thickness, causing appearance defects and increased rework.
Manufacturers have long sought a reliable solution to these challenges, especially for high-volume operations where consistency and efficiency are critical.
ZHYAO’s Solution
ZHYAO’s latest system combines optimized robotic gun positioning, stable electrostatic parameters, and real-time thickness monitoring. By adjusting spray angles and maintaining consistent voltage, current, and powder flow, the solution ensures even coating across all surfaces, including complex geometries.
Standardized handling procedures and real-time monitoring further minimize operator-induced variability, allowing manufacturers to maintain consistent quality across multiple batches. Early adopters have reported measurable improvements in first-pass yield and reductions in material waste.

Benefits for Manufacturers
Enhanced Coating Consistency: Achieve uniform layers on small hardware parts, improving both aesthetics and corrosion resistance.
Reduced Rework and Scrap: Higher first-pass yield saves time and production costs.
Optimized Powder Usage: Predictable consumption improves cost control and sustainability.
This solution not only addresses technical challenges but also delivers tangible business value, helping manufacturers meet customer expectations while improving operational efficiency.
