SAI Alcoa Process Comparison

  1. 1. vs. 製程比較
  2. 2. SAI Engineering Process Developing Forge Tooling (CAD/CAE) Flow Forming Heat Treatment Machining Polishing Painting
  3. 3. <ul><li>鋁柱 下料 鍛造 旋型 </li></ul><ul><li>使用 Dubai 將鋁柱依固定尺寸 使用 7000T 成型鍛機 投入鍛胚利用旋型 </li></ul><ul><li>10“~12” 鋁錠 鋸切成塊 加上 800T 鍛機撐開 加長胎環部位 </li></ul><ul><li>拋光 機械加工 熱處理 </li></ul><ul><li>以專用機台製作 首先以 CNC 車床加工輪廓 將已成形之胚料 , 以 T6 熱處理 </li></ul><ul><li>前輪及後輪的鏡面拋光 再使用 CNC 銑床加窗口 進行機械性強化 </li></ul><ul><li>( 塗裝 ) 包裝 出貨 </li></ul><ul><li>此製程通常只上透明精油 場內有棧板包裝 </li></ul><ul><li>但因卡車鋁圈的特殊拋光 或紙箱包裝 </li></ul><ul><li>大部份不上透明漆 </li></ul>
  4. 4. CNC 成型加工 ( 車床 ) ( 無此製程 ) 旋型 鍛造及熱處理 鋁錠下料 ALCOA SAI Process
  5. 5. 包裝 吊掛清洗上漆 自動拋光 CNC 成型加工 ( 铣床 ) ALCOA SAI Process
  6. 6. Comparison of “SAI Chrome” and “ Alcoa DuraBright” Alcoa Durabright SAI Chrome SAI Chrome Wheel is superior in brightness and clarity
  7. 7. Comparison Summary <ul><li>Surface treatment of “SAI Chrome” is superior in appearance, hardness, and anti-scratch. </li></ul><ul><li>With respect to chemical related resistance test such as salt spray and CASS, “SAI Chrome” provide better resistance than “Alcoa Durabright”, which is prone to result in white spots on the surface. </li></ul>
