Project Background

A metal waste bin manufacturer in Baoding, China required a powder coating solution for outdoor waste bins used in municipal, residential, and public sanitation projects. Since these products are exposed to sunlight, rain, and frequent daily use, the customer needed a stable coating process to improve surface durability and product appearance.

To support increasing production demand, the customer planned to upgrade from manual spraying to a more organized powder coating production line.

Client Challenges

Waste bins have different shapes and sizes, requiring flexible conveying and spraying arrangements

Outdoor use requires stable coating adhesion and corrosion resistance

Manual spraying caused uneven coating quality and low production efficiency

Frequent color changes affected production continuity

Production environment needed improvement for cleaner operation
