For metal castings, the commonly used surface treatment methods are mechanical polishing, chemical treatment, surface heat treatment, and spraying. Surface treatment is to clean, sweep, remove burrs, oil stains, and oxide scales on the surface of the workpiece.
There are generally two interpretations of surface treatment in China. One is a broad definition of surface treatment, which includes various physical and chemical methods such as pre-treatment, electroplating, painting, chemical oxidation, and thermal spraying; Another type is narrow surface treatment, which only includes sandblasting, polishing, which is commonly referred to as the pre-treatment part.
Beijing Dajiang Industrial continues to innovate and improve its metal surface treatment technology, providing customers with high-quality, efficient, and environmentally friendly products.
