1.济南注塑加工液压油中混入空气。主宴由于管接头，液压泵，液压缸等密不好。表现在油箱上有气泡。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.液压油中混入水分。会使油液变成乳白色。主宴原因冷却器漏水。Hydraulic oil mixed with water. Will turn the oil into Milky white. Main reason why the cooler cooler leakage.

3.济南注塑加工液压油中混入固体杂质。主要是切屑，焊渣，锈片以及金属粉未。Ji'nan injection molding hydraulic oil mixed with solid impurities. Mainly chip, welding slag, rust and metal powder.

4.油中产生胶质状物质。主宴是密封件被油液浸蚀或油液变质，使油液中产生胶状物质，这种胶质状物质常常使小孔堵塞。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.济南注塑加工比例线性差，开合模时间位置调节不良，检查放大板斜升斜降，调整放大板斜升斜降，时间适当调整。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.锁模机铰润滑不良，检查哥林柱，二板滑脚，机铰润滑情况, 加大润滑。Locking machine hinge lubrication is bad, check the elder brother column, the second board feet, machine hinge lubrication, increase lubrication.

7.济南注塑加工模具锁模力过大，检查模具受力时锁模力情况，视用户产品情况减少锁模力。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.头二板平行度偏差，检查头板二板平行度。调整二板，头板平行误差。The second board parallelism deviation, check the head board parallel. Adjusting the parallel error of the plate.

9.济南注塑加工机慢速转快速开模位置过小，速度过快。检查慢速开模转快速开模位置是否恰当，慢速开模速度是否过快。加长慢速开模位置，降低慢速开模的速度。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.
