拉丝工艺是一种新型的铝板表面处理工艺，主要以铝材、铝板为基材，采用拉丝轮、拉丝砂带或尼龙环带对表面进行拉出所需的纹理，拉丝工艺经过压型、滚涂等多种化学处理而成，具有表面色泽光亮、均匀、时尚感强，给人以强烈的视觉冲击的特点。拉丝处理是要在冲压之后再做的，拉丝可根据装饰需要，制成直纹、乱纹、螺纹、波纹和旋纹等几种。
Wire drawing process is a new type of aluminum plate surface treatment process, which mainly takes aluminum and aluminum plate as the base material, and uses wire drawing wheel, wire drawing sand belt or nylon ring belt to pull out the required texture on the surface. The wire drawing process is formed by pressing, roller coating and other chemical treatments. It has the characteristics of bright, uniform surface color, strong sense of fashion and strong visual impact. Wire drawing is to be done after stamping. Wire drawing can be made into straight lines, random lines, threads, ripples and rotary lines according to decorative needs.
直纹拉丝是指在铝板表面用机械磨擦的方法加工出直线纹路。它具有刷除铝板表面划痕和装饰铝板表面的双重作用。直纹拉丝有连续丝纹和断续丝纹两种。连续丝纹可用百洁布或不锈钢刷通过对铝板表面进行连续水平直线磨擦（如在有靠现装置的条件下手工技磨或用刨床夹住钢丝刷在铝板上磨刷）获取。改变不锈钢刷的钢丝直径，可获得不同粗细的纹路。断续丝纹一般在刷光机或擦纹机上加工制得。制取原理：采用两组同向旋转的差动轮，上组为快速旋转的磨辊，下组为慢速转动的胶辊，铝或铝合金板从两组辊轮中经过，被刷出细腻的断续直纹。

Straight line wire drawing refers to machining straight lines on the surface of aluminum plate by mechanical friction. The utility model has the dual functions of removing scratches on the surface of aluminum plate and decorating the surface of aluminum plate. There are two kinds of straight line drawing: continuous line drawing and intermittent line drawing. Continuous silk lines can be obtained by continuous horizontal and linear friction on the surface of aluminum plate with cleaning cloth or stainless steel brush (such as manual technical grinding under the condition of existing device or grinding on aluminum plate with wire brush clamped by planer). By changing the steel wire diameter of the stainless steel brush, lines of different thickness can be obtained. Intermittent silk lines are generally processed on a polishing machine or a texturing machine. Preparation principle: two groups of differential wheels rotating in the same direction are adopted. The upper group is a fast rotating grinding roller and the lower group is a slow rotating rubber roller. Aluminum or aluminum alloy plate passes through the two groups of rollers and is brushed with fine intermittent straight lines.
乱纹拉丝是在高速运转的铜丝刷下，使铝板前后左右移动磨擦所获得的一种无规则、无明显纹路的亚光丝纹。这种加工，对铝或铝合金板的表面要求较高。
Random wire drawing is a kind of irregular matte wire pattern without obvious lines obtained by moving and rubbing the aluminum plate back and forth, left and right under the high-speed copper wire brush. This processing has high requirements for the surface of aluminum or aluminum alloy plate.
波纹一般在刷光机或擦纹机上制取。利用上组磨辊的轴向运动，在铝或铝合金板表面磨刷，得出波浪式纹路。
Corrugations are generally made on a brushing machine or a texturing machine. Using the axial movement of the upper group of grinding rollers, grind and brush on the surface of aluminum or aluminum alloy plate to obtain wavy lines.
旋纹也称旋光，是采用圆柱状毛毡或研石尼龙轮装在钻床上，用煤油调和抛光油膏，对铝或铝合金板表面进行旋转抛磨所获取的一种丝纹。它多用于圆形标牌和小型装饰性表盘的装饰性加工。
Rotary pattern, also known as optical rotation, is a kind of silk pattern obtained by rotating and polishing the surface of aluminum or aluminum alloy plate with cylindrical felt or stone grinding nylon wheel installed on the drilling machine and kerosene mixed with polishing paste. It is mostly used for decorative processing of circular signs and small decorative dials.
螺纹是用一台在轴上装有圆形毛毡的小电机，将其固定在桌面上，与桌子边沿成60度左右的角度，另外做一个装有固定铝板压茶的拖板，在拖板上贴一条边沿齐直的聚酯薄膜用来限制螺纹竞度。利用毛毡的旋转与拖板的直线移动，在铝板表面旋擦出宽度一致的螺纹纹路。
The thread is fixed on the table by a small motor equipped with circular felt on the shaft at an angle of about 60 degrees with the edge of the table. In addition, a carriage equipped with fixed aluminum plate for pressing tea is made, and a polyester film with straight edge is pasted on the carriage to limit the thread competition. The rotation of the felt and the linear movement of the carriage are used to spin and wipe the thread pattern with the same width on the surface of the aluminum plate.
喷砂处理是为了获得膜光装饰或细微反射面的表面，以符合光泽柔和等特殊设计需要。均匀适度的喷砂处理，基本上也可以克服铝材表面的常见缺陷。
Sand blasting is to obtain the surface of film light decoration or fine reflection surface, so as to meet the special design needs such as soft luster. Uniform and moderate sand blasting can basically overcome the common defects on the aluminum surface.
