Chinese manufacturer Dajia develops advanced aluminium anodising and spray coating

Foshan Dajia Electromechanical Technology Co., Ltd. is expanding its focus on automated and precision-based surface treatment systems for the aluminium industry through its Mingtu Painting division.

Based in Foshan, the company develops anodising, electrophoretic coating, electrostatic powder coating and paint spray coating systems for aluminium profile manufacturers. The company said rising global demand for high-performance aluminium surface treatments is driving greater use of automated production systems designed to improve consistency, reduce labour costs and lower material waste.

The company’s operations combine two areas of expertise. While Dajia Electromechanical focuses on the design and manufacturing of anodising and electrophoretic coating systems, Mingtu Painting handles the planning, design and installation of powder and paint spray coating lines.

The company said its systems are based on European and American industrial technologies adapted for large-scale aluminium processing operations. The shift from semi-automatic to fully automatic coating systems has become important for manufacturers seeking better production efficiency and more uniform coating quality.
