What are the methods of custom finishing of aluminum profiles

1. Sandblasting

Uses the influence of high velocity sand flow to clean and roughen metal surfaces. Surface treatment of aluminum in this way can obtain a certain degree of cleanliness and different roughness on the surface of the workpiece, improve the mechanical properties of the workpiece surface, thereby improve the fatigue resistance of the workpiece, increase its adhesion to the coating, and prolong the coating. life. service life. .Durable for paint leveling and decorating. We often see aluminum alloy technology in various products of mobile phones, and it is increasingly adopted by existing TV covers or middle frames.


The processing of finished aluminum products adopts mechanical, chemical or electrochemical methods to reduce the surface roughness of automotive aluminum parts, so as to obtain a bright and flat surface. The polishing process is mainly divided into mechanical polishing, chemical polishing and electrolytic polishing. The automotive aluminum parts are mechanically polished + electrolytic polishing, which can be close to the mirror effect of stainless steel, giving people a high-end, simple and fashionable sense of the future (of course, it is easy to leave fingerprints, which needs to be done).

Aluminum profile processing


Metal wire drawing is a manufacturing process that repeatedly scratches aluminum sheets with sandpaper. Drawing can be divided into linear drawing, random drawing, spiral drawing and thread drawing. Metal processing WeChat, the content is good, it is worthy of attention. The brushed metal process can clearly show every tiny silk screen, allowing the brushed metal to exude a delicate hair luster. This product is both stylish and technical.

4.High gloss cut

Using an engraving machine, a diamond knife is reinforced on the engraving machine spindle rotating at high speed (typically 20,000 rpm) and the part is cut to create localized highlight areas on the product surface. The brightness of the cutting highlights is affected by the milling and drilling speed. The faster the drilling speed, the brighter the cutting highlights, and vice versa, the darker the color, the easier the cutting line is. Metal processing WeChat, the content is good, it is worthy of attention.


Anodizing refers to the electrochemical oxidation of metals or alloys. Under the corresponding electrolyte and specific process conditions, aluminum and its alloys form oxide films on aluminum products (anode). Anodizing can not only solve the defects of aluminum surface hardness and wear resistance, but also prolong the service life of aluminum and enhance its aesthetics. It has become an indispensable part of aluminum surface treatment and is currently the most widely used and successful process.
