1.濟南注塑加工液壓油中混入空氣。主宴由于管接頭，液壓泵，液壓缸等密不好。表現在油箱上有氣泡。Ji'nan injection molding hydraulic oil mixed with air. Due to the main pipe joints, hydraulic pumps, hydraulic cylinders, etc.. There are bubbles in the fuel tank.

2.液壓油中混入水分。會使油液變成乳白色。主宴原因冷卻器漏水。Hydraulic oil mixed with water. Will turn the oil into Milky white. Main reason why the cooler cooler leakage.

3.濟南注塑加工液壓油中混入固體雜質。主要是切屑，焊渣，銹片以及金屬粉未。Ji'nan injection molding hydraulic oil mixed with solid impurities. Mainly chip, welding slag, rust and metal powder.

4.油中產生膠質狀物質。主宴是密封件被油液浸蝕或油液變質，使油液中產生膠狀物質，這種膠質狀物質常常使小孔堵塞。A gelatinous substance in oil. The main feast is sealed by oil erosion or oil deterioration, so that the oil in the production of colloidal substances, which are often blocked by the gelatinous material.

5.濟南注塑加工比例線性差，開合模時間位置調節不良，檢查放大板斜升斜降，調整放大板斜升斜降，時間適當調整。The proportion of injection molding process in Ji'nan is poor, the timing of the opening and closing of the mold is not adjusted well, and the inclined angle of the plate is inclined to be adjusted.

6.鎖模機鉸潤滑不良，檢查哥林柱，二板滑腳，機鉸潤滑情況, 加大潤滑。Locking machine hinge lubrication is bad, check the elder brother column, the second board feet, machine hinge lubrication, increase lubrication.

7.濟南注塑加工模具鎖模力過大，檢查模具受力時鎖模力情況，視用戶產品情況減少鎖模力。Ji'nan injection molding mold clamping force is too large, check the mold force when clamping force, depending on the user's product to reduce the clamping force.

8.頭二板平行度偏差，檢查頭板二板平行度。調整二板，頭板平行誤差。The second board parallelism deviation, check the head board parallel. Adjusting the parallel error of the plate.

9.濟南注塑加工機慢速轉快速開模位置過小，速度過快。檢查慢速開模轉快速開模位置是否恰當，慢速開模速度是否過快。加長慢速開模位置，降低慢速開模的速度。Ji'nan injection molding machine slow to open the mold position is too fast, too fast. Check the slow open mold to open the mold position is appropriate, slow mold speed is too fast. Extend the slow opening position, slow down the speed of mold opening.
