Brushed aluminum sheet plate is commonly used in the West to describe brushed aluminum sheet, which means that the surface of the aluminum sheet is processed by mechanical friction or extrusion to produce straight lines. Wire drawing can be made into straight, cross, chaotic, thread, corrugated and twisted patterns according to the needs of decoration:
Straight wire drawing
Refers to machining a straight line on the surface of the aluminum sheet by mechanical friction Lines. It has the dual function of removing scratches on the surface of the aluminum sheet and decorating the surface of the aluminum sheet. There are two types of straight wire drawing: continuous wire and intermittent wire. Continuous thread patterns can be obtained by scouring pads or stainless steel brushes through continuous horizontal straight-line rubbing on the surface of the aluminum sheet (such as manual grinding under the condition of existing equipment or using a planer to clamp the wire brush on the aluminum sheet). By changing the wire diameter of the stainless steel brush, textures of different thicknesses can be obtained. Intermittent silk patterns are generally processed on brushing machines or rubbing machines. Production principle: Two sets of differential wheels rotating in the same direction are used. The upper set is a fast-rotating grinding roller, and the lower set is a slow-rotating rubber roller. The aluminum or aluminum alloy sheet passes through the two sets of rollers and is brushed out. Delicate intermittent straight lines.
Generally processed on a brushing machine or rubbing machine. The aluminum or aluminum alloy sheet passes through the two sets of rollers, and the surface of the aluminum sheet is pressed out of the cross pattern.
Random pattern drawing
Under the high-speed copper wire brush, the aluminum sheet is moved back and forth, left and right, and rubbed to obtain an irregular, non-obvious matte silk pattern. This kind of processing has higher requirements on the appearance of aluminum or aluminum alloy sheets.
It is generally made on a brushing machine or a rubbing machine. Using the axial movement of the upper group of grinding rollers, the surface of the aluminum or aluminum alloy sheet is brushed to obtain wave patterns.
It is also called optical rotation. It is a kind of silk pattern obtained by rotating and polishing the surface of aluminum or aluminum alloy sheet by using cylindrical felt or grind nylon wheel to install it on a drilling machine. It is mostly used for decorative processing of round signs and small decorative dials.
Use a small motor with a circular felt on the shaft, fix it on the table, and make an angle of about 60 degrees with the edge of the table, and make a carriage with a fixed aluminum sheet for pressing tea, and stick an edge on the carriage The straight polyester film is used to limit the thread competition. Using the rotation of the felt and the linear movement of the carriage, the surface of the aluminum sheet is rubbed with a thread pattern of the same width. Of course, it needs to be drawn first and then electroplated.
Before bending and other molding, it is usually flat wire drawing. In fact, the appearance treatment has high requirements for the pretreatment of the substrate, otherwise the defects of the substrate will be amplified after the appearance treatment.
The appearance of general aluminum alloy products is not electrosheetd, but various colors produced by oxidation.
Anodizing has heard that, for aluminum, it is mainly to strengthen the hardness of the surface (a layer of ceramic) to enhance the anti-friction performance.
Hot stamping is also a type of thermal transfer.
Die-cast aluminum parts are painted with a protective film that can be painted on the surface to prevent oxidation.
Of course, die-casting parts can also be treated with surface oxidation. The matte appearance can be done, but the effect of frosting is the preliminary process of surface oxidation treatment realized by sandblasting. The sandblasting process is briefly introduced:
Sandblasting is to obtain the appearance of film decoration or subtle reflective surface to meet special design needs such as soft gloss. At the same time, it can make the combination of printing material and substrate stronger during silk screen printing. Sandblasting is usually carried out in a dedicated sandblasting machine. According to the requirements of the thickness of the sand surface, select the appropriate mesh of quartz sand and spray it into an appropriate sand surface. Even and moderate sandblasting can basically overcome the rare defects in the appearance of aluminum.
The appearance of aluminum alloy products is electroplated, and the appearance of aluminum alloy products can not be oxidized in various colors. Only authentic aluminum products can produce various colors through oxidation.
Wire drawing aluminum plates are an manufacturing process of repeatedly scraping the aluminum sheet out of lines with sandpaper. The main process of the process is divided into three parts: deesterification, sand mill, and water washing. In the aluminum sheet wire drawing process, the special coating technology after the anode treatment can make the surface of the aluminum sheet generate a coating layer containing the metal component, clearly showing every minute trace, so that the metal matte will show fine hair. Silk luster. More and more metal shells of aluminum sheet products use metal wire drawing process to play a beautiful and anti-erosion effect. Make the product have both fashion and technology elements. This is one of the reasons why the process is so popular.
In the aluminum sheet pressure processing, the aluminum sheet is forced through the mold under the action of external force, the cross-sectional area of the metal is compressed, and the technical processing method to obtain the required cross-sectional area shape and size is called the aluminum sheet drawing process. To change the shape and size The tool is called a drawing die. The process is double-sided drawing effect with clear lines. Therefore, the brushed aluminum sheet is generally used in high-end places or products. Mainly rely on imported supplies, not many domestic manufacturers master the process.
Scope of application
Brush finishd aluminum sheets are widely used in brushed aluminum composite panels, fireproof panels, aluminum photo frames, integrated ceilings, boutique cabinets, boutique doors and windows, veneer panels, signs, lighting, indoor and outdoor decoration, household appliances, luggage, gifts, furniture, consumer electronics and other fields.
