Straight line drawing refers to machining a straight line on the surface of aluminum plate through mechanical friction. It has the dual function of removing scratches on the surface of aluminum plate and decorating the surface of aluminum plate. There are two types of linear drawing: continuous drawing and intermittent drawing. Continuous silk screen patterns can be obtained by continuous horizontal linear friction on the surface of the aluminum plate with a cleaning cloth or stainless steel brush (such as manual grinding under equipment conditions or grinding on the aluminum plate with a planer knife clamping wire brush). By changing the diameter of steel wire of stainless steel brush, different thickness of steel wire can be obtained. Intermittent screen printing is usually done on a brush machine or friction machine. Manufacturing principle: Two sets of differential wheels rotate in the same direction. The upper group is the fast rotary roller, and the lower group is the slow rotary rubber roller. Aluminum or aluminum plates are brushed through two sets of rollers to form fine, discontinuous lines.
Disordered wire drawing is the irregular, not obvious matte wire obtained by moving aluminum plate back and forth under the action of high-speed copper wire brush. This processing has higher requirements for the surface of aluminum or aluminum alloy plates.
Wrinkling is usually done in a brush or striping machine. The surface of aluminum or aluminum alloy plate is polished by the axial motion of the previous set of grinding rolls to obtain waveform.
The rotating pattern, also known as the optical rotation pattern, is a linear pattern obtained by rotating the surface of the aluminum or aluminum alloy plate by mixing kerosene and polishing paste with a cylindrical felt or stone nylon wheel mounted on the drill press. Mainly used for circular signs, small decorative dial decoration processing.
The wire is a small motor with round felt on the shaft, which is fastened to the table at an Angle of about 60 degrees from the edge of the table. In addition, also made a fixed aluminum plate tea press car. Attach mylar to the frame to limit yarn competition. By using the rotation of the felt and the straight motion of the trolley, lines of equal width are carved on the surface of the aluminum plate.
Sandblasting is done to obtain a membrane-decorated surface or a surface with good reflectivity to meet special design requirements such as a soft sheen. Uniform and moderate sand blasting can basically overcome the common defects of aluminum surface.
Exterior parts, whether drawn or sandblasted, are usually treated with surface oxidation. When selecting the machining process, problems related to shape should be considered. These two processes can obtain surface textures or differences.
In addition, there is a similar sand blasting process, but its corrosion is chemical corrosion method, commonly known as sand chemical treatment or chemical sand surface corrosion, especially suitable for aluminum surface treatment, the sand surface uniformity is far better than sand blasting. The surface corrosion of chemical sand can be divided into acid corrosion and alkaline corrosion. Different corrosive solvents and sanding agents are used to obtain different surface colors and particle sizes.
