2、uch as best condition 目的：正確的清理螺桿，使螺桿達到最佳狀態(tài)，并最大程度減少黑點。2. Application : This SOP can be applied in cleaning injection machine screw 用途：此用途只用來清洗注塑機螺桿。3. Injection Machine Screw : 螺桿清洗時如圖放置4. Operating Procedure : Screw Cleaning 螺桿清洗的操作流程：4-1. Preparing equipments for cleaning Brush, Grinder, Bronze Kni

3、fe and Cleaning Cloth, etc 準備工具：刷子、打磨片、銅刀、清潔布等如圖所示4-2. Preparing equipments for safety Face mask, Heat resistance glove, etc 防護用品：面罩、隔熱手套等，如圖所示4-3. Removing all remained resin in cylinder inside after operating with CF-1051/F18029 按照CF-1051/F18029標準清除料筒內部殘留塑料4-4. Adjusting cylinder temperature as fo

4、llowings after removing all remained resin 清除所有殘留后，把料筒各段溫度調整至如圖所示：4-5. Nozzle H1 H2 H3 200 190 190 160 4-6. Cleaning(pursing) with SAN resin(HR-5330) after cooling down 待溫度降至上表設定值后，用SAN料清洗。4-7. Starting disassembling of screw after enough cleaning 在充分清理后，拆卸螺桿。4-8. Removing resin on the surface of sc

5、rew as following procedure after cooling in air 待螺桿冷卻后，依照下列步驟清除螺桿表面的塑料。4-9. Removing cooling downed SAN(HR-5330) resin by knocking with bronze knife 待冷卻后，用銅刀去除螺桿表面的SAN料，如圖所示：4-10. Removing all remained resin with grinder as followings 用銅質打磨片對螺桿表面進行拋光，如圖所示： 4-11. After grinding, disassembling “check-

6、ring” in the front of screw 打磨后，拆卸螺桿三件套進行檢查4-12. Burning disassembled front of screw and check-ring in the furnace at 500, 10mins 把三件套加熱至500，保持10分鐘。4-13. Cleaning inside of barrel with stick coved by cloth 用布清洗螺桿內壁；4-14. Assembling screw 組裝螺桿5. Maintaining injection machine : 注塑機維護5-1. Maintaining i

7、njection machine as “power on as lower temperature during non-operating time 在機器不運行時，炮筒溫度盡可能降低。5-2. Recommended temperature 建議設定溫度如下： Nozzle H1 H2 H3 120 120 120 120 * Its most important factor which is related with burning of resin inside cylinder （原料在高溫下長時間停留在炮筒內壁是導致原料碳化的主要原因）5-3. Screw cleaning i

8、s recommended after long-term non-operating period 建議當機器長時間不運轉時清理螺桿【W(wǎng)orkplace Safety Precautions 工作區(qū)域安全防范1) Wearing safety equipments for avoiding the risk of burn by high temperatured resin (heat resistance glove, apron, etc) 為避免高溫塑料的燙傷，在工作之前應穿戴防護用品。如：隔熱手套等。2) Wearing safety goggles for protecting

9、eyes by resin particles during removing resin on screw 清理時戴防護眼鏡。3) Power-off the injection machine during screw cleaning 在清理時關閉機器電源。4) Power-on during assembling screw 安裝螺桿時打開電源。5) Starting procedure of screw assembling after checking set-value and present-value temperature 在檢查設定值和當前溫度值后，開始按作業(yè)標準安裝螺桿6) Operating should be pair work (two person in group) 以兩人一組完成工作。 Prepared byLimei DengReviewed byGuangbing QinApprove
