ã€China Aluminum Industry Network】 According to the needs of the decoration, drawing can be made into straight lines, random lines, threads, corrugations and swirl lines. Straight-line drawing means that a straight line is machined on the surface of the aluminum plate by mechanical rubbing. It has the dual role of brushing off the aluminum surface scratches and decorative aluminum surface. There are two kinds of continuous wire drawing and intermittent wire drawing. The continuous thread can be obtained by using a scouring pad or a stainless steel brush by continuously horizontally rubbing the surface of the aluminum plate (for example, hand grinding with an existing device or brushing the aluminum plate with a planer). Change the wire diameter of the stainless steel brush to obtain different thickness lines. Intermittent thread is usually processed on a brush or a rubbing machine. The principle of making: using two sets of differential rotating wheels with the same direction, the upper set is a rapidly rotating grinding roller, the lower set is a slowly rotating rubber roller, aluminum or aluminum alloy plate passes through two sets of rollers, and is brushed out Delicate, intermittent lines. Random pattern drawing is a kind of irregular matt silk pattern with no visible lines obtained by moving the aluminum plate forward and backward and left and right under the high-speed copper wire brush. This kind of processing requires high surface quality for aluminum or aluminum alloy plates. Ripples are usually made on a brush or a scribing machine. Using the axial movement of the upper set of grinding rollers, the surface of the aluminum or aluminum alloy plate is brushed to obtain a wave pattern. Spinning, also known as rotation, is the use of cylindrical felt or grinding stone nylon wheel mounted on the drill, with kerosene and polishing paste polishing, aluminum or aluminum alloy plate surface rotation grinding and grinding obtained by a silk pattern. It is mostly used for decorative processing of round signs and small decorative dials. The thread is a small motor equipped with a round felt on the shaft, which is fixed on the table, and is at an angle of about 60 degrees with the edge of the table, and is made of a dragging plate with a fixed aluminum plate for pressing the tea. A polyester film with straight edges is used to limit the thread race. By using the rotation of the felt and the linear movement of the carriage, a thread pattern with the same width is spun on the surface of the aluminum plate. Of course, it must be electroplated after drawing. Before the bending and other molding, it is generally a flat wire drawing. In fact, the surface treatment has high requirements for the pre-treatment of the substrate, otherwise, the surface treatment will in turn amplify the defect of the substrate. The surface drawing of the plastic parts is generally done by bronzing. Under the high temperature and high pressure of the bronzing machine, the materials on the bronzing film are transferred to the plastic surface. Different gilding films are used to obtain different luster and thickness lines. This process is used on many DVD panels. Nowadays, many of the magic mirror decoration parts used in audiovisual products are reflective film (also useful for electroplating) on ​​the surface of PMMA sheet. In addition to wire drawing, the surface treatment of aluminum is also commonly used in sand-blasting. It can also cover masking. The role of marks and beautification appearance There is also a "hot stamping" process (aluminum transfer) that can produce similar effects on the surface of plastic parts. For the hot stamping plate, that is, the material selection of the pressure head part, the red copper material is preferable because the red copper has better heat dissipation and heat conductivity, and is a neutral material in the metal, and is neither too soft nor too light. Hard, not only easy to process, there is a certain degree of elasticity, durability is good; but in actual use, many manufacturers choose aluminum alloy printing plates to reduce the cost of materials, so that the production cost of hot plate can save some, but because of aluminum The material is too soft and its service life is poor. If the batch is large, it will take a period of time to re-plate, and the plate-making fee is not cheap. Therefore, the material selection problem should be considered comprehensively. The hot stamping process conditions are relatively easy to understand, that is, hot stamping pressure, hot stamping temperature and hot stamping time. More important is the choice of hot stamping materials, that is, hot stamping paper. When selecting, it is necessary to pay attention to matching with different hot stamping substrates. It is not a kind of hot stamping paper that can take all the materials. This is mainly related to thermal transfer. The problem of firmness of adhesion. This may be inconvenient to directly compare, because the two processes are applicable to different occasions, drawing is suitable for sheet metal parts, and hot stamping is applied to paper, plastic, fabrics, if you want to do comparison, you must consider the difference between the mold and structural design caused by Other cost changes are justified.
