【正文】 D. Canon Ruby Finger Strap ? Process: casting → polishing → plating → laser carved. ? 工藝： 壓鑄 → 拋光 → 電鍍 → 雷射 Logo. 。 C. NOKIA Light Saber ? Process: – Metal piece: lathe → polishing → plating → laser carved. – Plastic part: injection → polishing. ? 工藝 : – 五金件： 車屑 → 拋光 → 電鍍 → 雷射 Logo。D相關(guān)產(chǎn)品工藝 A. CWM Identifier N series ? Process: stamping → polishing → oxidation aluminum → surface printing → logo printing. ? 工藝：沖壓 → 拋光 → 鋁材氧化 → 表面 絲印 → 絲印 Logo。 2. 達(dá)克羅： 鋅鉻涂層 ，是一種高耐蝕涂層，生產(chǎn)過(guò)程對(duì)環(huán)境基本無(wú)污染 。 11. 拉絲 Drawbench Stamping 沖壓 Polishing 拋光 Process: Cutting 切割 Oxidation 氧化 Use cutting machine to form regular line, arc, circle on metal surface, this process is called CD line cutting. 1/. The process is easier to achieve at aluminum material than stainless steel. Rigid cutter is required if we want to cutting at stainless steel. 2/. This process can dispose curve surface, normally method is: cutting at flat surface, then forming the metal part to special shape, to achieve curve surface. 3/. One fixture is required to fix the part which planed to cut. CD紋是使用切刀在產(chǎn)品表面形成規(guī)則的線，弧線，圓等的加工工藝。 Dyeing氧化 Shiny Logo批花 Shiny logo process will be arranged after plating or oxidation, use milling cutter to remove the plating or oxidation surface and show inherent metal color. 1/. One fixture is required to fix the part which planed to mill. 2/. Different milling directions can be achieved. 3/. Use etching or stamping process to make emboss Logo. Aluminum material is easier to achieve this process than stainless steel. 批花使用銑刀切除部件表面的電鍍或氧化層，使部件局部爆裂原材料的加工工藝。 Dyeing氧化 Sand blast process is using one sand gun to spray small sand at part surface, to achieve smatt surface. 1/. Part can not too soft. 2/. There is special sand blast machine. 噴沙是使用沙槍在產(chǎn)品表面噴上一層細(xì)沙，從而使產(chǎn)品表面形成磨沙感。 Dyeing氧化 The color sample is made by aluminum, through oxidation and dyeing disposal to achieve different color. 1/. The color can be adjusted, but can not achieve gradual change effect at one surface. 2/. Currently, oxidation process can pass salt spray test, but no all the parts can pass wearing vibration test. 3/. This process can be used for logo tage which is wanted to achieve different color. 4/. Yield rate will be reduced if we want to make differenct color at one part, for instance: first round oxidation yield is 95%, after second round oxidation yield rate will be reduced to 90% or below. 氧化的顏色選擇性很強(qiáng)，可以在一個(gè)部件上實(shí)現(xiàn)不同的顏色，但相應(yīng)的不良率會(huì)增加。 6. 蝕刻 Etched Stamping 沖壓 Polishing 拋光 Process: Plating 電鍍 Laser 雷射 Laser Carved process is using laser to remove surface material of part. 雷射工藝是使用激光將部件表層材料去除后，到達(dá)需要的圖案或 Logo。 圖 1 圖 2 5. 拋光 Polishing 不能拋光區(qū)域 Figure 2 Figure 1 粗糙區(qū)域 針對(duì)拋光不到位的區(qū)域，如果我們需要消除其粗糙的表面，需要額外增加工序，如：細(xì)拋、手工拋，增加夾制具，導(dǎo)致相應(yīng)的費(fèi)用也會(huì)增加。 4) – Topaz brown: as PVD layer is brittle, one small crack can be seen after stamping. (Figure 5) Surface Crack 5. 拋光 Polishing 5. 拋光 Polishing NOKIA Sonja 存在問(wèn)題點(diǎn) 產(chǎn)品中間的位置厚度較大，壓合后中間比兩頭要大 ~。 4) Casting Part After Polishing and plating After Stamping Positive
