Causes and repair methods of screw barrel damage The cause of damage to the screw barrel 1. The screw rotates in the barrel, and the friction between the material and the two causes the working surface of the screw and barrel to gradually wear: the diameter of the screw gradually decreases, and the diameter of the inner hole of the barrel gradually increases. In this way, the diameter
What are the cleaning methods for the barrel screw? Screw is an important part of injection molding machine. Its role is to transport, compact, melt, stir and apply pressure to plastics. The structure of the screw barrel is a round tube with a discharge opening in the middle. What are the cleaning methods for screw barrels? What are the cleaning methods for the barrel screw? 1. Adop
What are the heating methods for the extruder barrel screw? Extruder barrel screw heating methods mainly include: resistance heating method, electric induction heating method and heating medium heating method. The current heating method is more resistance heating method. Extruder barrel screw heating method 1. Resistance heating method is to pass current through a relatively la
How to extend the service life of the screw of the injection molding machine? The method to extend the service life of injection molding machine screw: 1) When the injection molding machine starts, it is necessary to fully warm up the injection molding. When the barrel reaches the pre-adjusted temperature, keep the temperature below Φ60mm for 15 minutes. After the above 30 minutes, st
What should be paid attention to if the screw barrel is not well plasticized? The screw barrel is not well plasticized and the following issues should be noted: 1. The plastic head has been cleaned or replaced! Remove the head and burn it with fire to completely burn the remaining material on the plastic head; 2. Carefully check, starting from the hopper, inner spring nozzle;
Extruder screw barrel heating and cooling Extruder screw barrel heating method: Simple heating is widely used in resistance heating, and thermocouples are used to achieve segmented temperature control and inspection side. Resistance heating is the use of resistance to generate heat to heat the barrel, and then transfer the heat to the plastic in the barrel. Resistance heating mainly incl
Use conditions and methods of extruder barrel screw Extruder screw barrel heating method: Jane heating widely uses the method of resistance heating, and uses thermocouples to achieve segmented temperature control and inspection side. Resistance heating is the use of resistance to generate heat to heat the barrel, and then transfer the heat to the plastic in the barrel. Resistance heating
Common materials and requirements for barrel screw Common materials and requirements for barrel screw Common materials for barrel screw: Nowadays, the most common and common barrel screw materials in my country are 45 steel, 40Cr, ammoniated steel and 38CrMOAl. The performance requirements of these materials are introduced one by one as follows: 1, 45 steel is relatively cheap
