拉絲工藝是一種新型的鋁板表面處理工藝，主要以鋁材、鋁板為基材，采用拉絲輪、拉絲砂帶或尼龍環帶對表面進行拉出所需的紋理，拉絲工藝經過壓型、滾涂等多種化學處理而成，具有表面色澤光亮、均勻、時尚感強，給人以強烈的視覺沖擊的特點。拉絲處理是要在沖壓之后再做的，拉絲可根據裝飾需要，制成直紋、亂紋、螺紋、波紋和旋紋等幾種。
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.
直紋拉絲是指在鋁板表面用機械磨擦的方法加工出直線紋路。它具有刷除鋁板表面劃痕和裝飾鋁板表面的雙重作用。直紋拉絲有連續絲紋和斷續絲紋兩種。連續絲紋可用百潔布或不銹鋼刷通過對鋁板表面進行連續水平直線磨擦（如在有靠現裝置的條件下手工技磨或用刨床夾住鋼絲刷在鋁板上磨刷）獲取。改變不銹鋼刷的鋼絲直徑，可獲得不同粗細的紋路。斷續絲紋一般在刷光機或擦紋機上加工制得。制取原理：采用兩組同向旋轉的差動輪，上組為快速旋轉的磨輥，下組為慢速轉動的膠輥，鋁或鋁合金板從兩組輥輪中經過，被刷出細膩的斷續直紋。

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.
亂紋拉絲是在高速運轉的銅絲刷下，使鋁板前后左右移動磨擦所獲得的一種無規則、無明顯紋路的亞光絲紋。這種加工，對鋁或鋁合金板的表面要求較高。
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.
波紋一般在刷光機或擦紋機上制取。利用上組磨輥的軸向運動，在鋁或鋁合金板表面磨刷，得出波浪式紋路。
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.
旋紋也稱旋光，是采用圓柱狀毛氈或研石尼龍輪裝在鉆床上，用煤油調和拋光油膏，對鋁或鋁合金板表面進行旋轉拋磨所獲取的一種絲紋。它多用于圓形標牌和小型裝飾性表盤的裝飾性加工。
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.
螺紋是用一臺在軸上裝有圓形毛氈的小電機，將其固定在桌面上，與桌子邊沿成60度左右的角度，另外做一個裝有固定鋁板壓茶的拖板，在拖板上貼一條邊沿齊直的聚酯薄膜用來限制螺紋競度。利用毛氈的旋轉與拖板的直線移動，在鋁板表面旋擦出寬度一致的螺紋紋路。
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.
噴砂處理是為了獲得膜光裝飾或細微反射面的表面，以符合光澤柔和等特殊設計需要。均勻適度的噴砂處理，基本上也可以克服鋁材表面的常見缺陷。
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.
