After using the injection molding machine barrel screw machine for a period of time, some users will find that they have encountered the phenomenon of screw slipping. Professionals said that the slipping situation is often caused by difficulty in pressing materials and the adhesion strength between the length of the barrel.
Analysis of the causes and solutions of the slip of the injection molding machine barrel screw
Of course, the specific slip also needs to be analyzed according to the situation. The injection molding barrel screw usually occurs in the pre-plastic stage, so that the axial movement of the screw is terminated, resulting in the product cannot be injected. In addition, if the pressure is too high or the screw is worn, the hopper design is unreasonable, etc., it may also cause slippage.
If the temperature of the rear part of the barrel is low, the screw will slip, and the molten film will not be produced until the temperature of the feeding section reaches a certain level. If the temperature is not enough, then the East polymer will melt or mix insufficiently, causing the screw to slip. One of the solutions is to slowly increase the temperature of the feeding section until the screw rotation and retreat can be coordinated.
Because of the processing equipment, the screw will also slip. Like the feeding section, when the screw rotates, the material will be unable to convey the material forward due to the shear force. Because of wear due to equipment, it should be checked whether the clearance between the screw and the machine exceeds the standard value.
In addition, the material properties, size, and size will affect the continuous feed, resulting in poor screw processing performance and screw slippage. Therefore, attention should be paid to materials with uniform properties, sizes, and sizes.If you want to know more about it please do not hesitate to contact me. WhatsApp:+86-15966835076.
