Brushed surface finishing is a finishing technique achieved by grinding the surface of a product to create decorative linear patterns. It has the ability to enhance the texture of metal materials.
Below we cover its applications, classifications, processing techniques, products, and the factors influencing the brushing process.
I.Applications of Brushed Surface Finishing
Metal surface treatments come in various forms, including sandblasting (resulting in a matte pearl silver surface), polishing (creating a mirrored finish), embossing (producing various textures), electroplating (covering with another metal layer), coating (applying non-metallic coatings), and brushing (producing a satin-like effect). Compared to other surface treatments, brushing provides a non-mirrored metallic luster, akin to a satin finish, adding a strong decorative element. This technique breathes new life into ordinary metals, which is why it has gained significant market acceptance and widespread application.
In industries such as construction, brushing is applied to elevator door panels, escalator decorative panels, and hardware items like faucets, hinges, handles, and lock plates. It's also prominent in furniture, including range hoods, stainless steel stoves, and sinks. The surge in 3C digital products in recent years has elevated the use of brushing, seen in panels and keyboard plates for laptops, as well as panels for phones, LCD frames, battery covers, protective slides for cameras, and more. Additionally, various electronic products like MP3 players, MP3 players, DVD players, projectors, etc., have also integrated brushing techniques.
II. Classification of Surface Brushing
Surface brushing does not have a standardized classification. It is typically categorized into straight lines and random lines, also known as filament patterns and snowflake patterns respectively. Preferences for these patterns are subjective, varying from user to user. Some may prefer the elegance of filament patterns, while others may favor the intricate details of snowflake patterns. The effect of these patterns is often challenging to describe or precisely define, instead, it is determined by the chosen processing method, the abrasive products used, and other process parameters.
III. Processing Techniques for Surface Brushing
The processing technique for surface brushing depends on the desired effect, as well as the size and shape of the workpiece. There are two main methods: manual and mechanical brushing.
Manual brushing involves skilled artisans who use handheld tools to create the desired surface effect. It allows for intricate detailing but may be more time-consuming and labor-intensive.
Mechanical brushing employs specialized machinery equipped with abrasive tools to achieve a consistent and precise brushing effect. It is suitable for large-scale production and ensures uniform results.
The application of surface brushing treatment is extensive and continues to grow in popularity. It is a versatile technique that enhances the aesthetics and texture of metal products, making it a valuable asset across various industries.
