In modern industrial manufacturing and decorative design, brushed plate sheet metal, as a common surface treatment process, is widely used in architectural decoration, home appliance shells, electronic equipment, automotive parts and other fields. Its unique metallic texture and delicate texture not only enhance the aesthetic beauty of the product, but also improve its corrosion resistance and wear resistance. However, in the actual production process, how to effectively control the texture quality of brushed plate sheet metal is the key to ensuring product consistency and high-end feeling.



One, Basic Principles of Wire Drawing Sheet Metal



Bare copper wire sheet metal is formed by mechanical or chemical methods on the surface of the metal to form a certain directional fine line (that is, 'texture'), thus forming a surface effect with visual and tactile aesthetics. Common wire drawing processes include mechanical wire drawing, abrasive belt wire drawing, electrolytic wire drawing, etc. Among them, mechanical wire drawing is the most widely used method at present due to its simple operation, low cost, and controllable effect.



Two, Key Factors for Texture Control



1. Abrasive Particle Size Selection



The particle size of the abrasive directly affects the fineness of the texture. The finer the particle size, the softer and finer the wire drawing texture; the coarser the particle size, the more obvious the texture and the stronger the visual impact. Therefore, it is crucial to choose the appropriate abrasive particle size according to the product usage and design requirements.



2. Wire Drawing Direction and Angle



The direction and angle of wire drawing determine the direction and level of the final texture. It is usually required to maintain a uniform wire drawing direction on the whole sheet metal part to avoid visual confusion. For irregular workpieces, the wire drawing path should be reasonably adjusted according to the structural characteristics to ensure the continuity and consistency of the texture.



3. Wire Drawing Speed and Pressure Control



During the wire drawing process, the operating speed of the equipment and the pressure applied to the workpiece surface are also important factors affecting the quality of the texture. Too fast speed may cause unclear or broken lines, while excessive pressure is easy to cause surface damage to the metal or too deep texture. Therefore, it is necessary to reasonably set the speed and pressure parameters according to the material thickness, hardness, and equipment performance.



4. Material Characteristics Influence



Different metal materials (such as stainless steel, aluminum plate, copper, etc.) have different hardness and ductility, which have a significant impact on the effect of wire drawing. For example, stainless steel material is harder, and the wire drawing texture is clearer and more stable after wire drawing; while aluminum alloy is prone to burrs and requires more precise operation.



5. Subsequent Treatment and Protection



After wire drawing, it often requires subsequent processing such as cleaning, passivation, spraying, or electroplating to enhance the durability and antioxidant capacity of the texture. If these process steps are not handled properly, they may cover or destroy the original texture, so it is necessary to consider comprehensively when designing the process flow.



Three, Quality Control and Standardized Production



In order to ensure the consistency of texture in mass production, enterprises should establish standardized operation procedures, including abrasive selection standards, equipment parameter setting tables, operation specifications, and regularly maintain and calibrate the equipment. In addition, the introduction of automatic wire drawing equipment can effectively improve efficiency and quality stability, and reduce human error.



Four, Conclusion



Bare copper wire as an important process for improving the appearance and texture of products, its texture control not only concerns the aesthetic performance but also relates to the overall quality and market competitiveness of the product. Through scientific material selection, precise process control and standardized management, enterprises can achieve efficient and stable control of the texture of the wire drawing, thus standing out in the fierce market competition. In the future, with the development of intelligent manufacturing technology, the control of wire drawing texture will become more refined and personalized, bringing more possibilities to industrial design.
