How to adjust the screw clearance of conical twin screw extruder? Conical twin-screw extruder is the main equipment for producing plastic profiles. When the profile is produced, the twin screw rotates outward in the barrel in different directions. The size of the screw gap not only affects the plasticizing effect of the material, but also affects the quality of the product, sometimes causing
How to increase the service life of injection molding machine screw? The screw is the main part of the injection molding machine. Its role is to transport, compact, melt, stir and pressure plastics. All this is accomplished by the rotation of the screw in the barrel. However, the screw of the injection molding machine is operated under high temperature, high pressure, high mechanical torque a
How to improve the efficiency of rubber extruder barrel screw? The reason for the noise of the barrel screw of the rubber extruder: 1. The assembly gap between the screw barrel of the rubber extruder and its supporting transmission shaft is too large. During rotation, the center lines of the two shafts are not concentric, and the error is too large. Second, the screw extruder of
What are the factors affecting the unstable quality of the extruder barrel screw? Factors affecting the unstable quality of the extruder barrel screw: 1. The screw gap of the extruder barrel is too large 1. The screw gap of the extruder barrel is too large, the flow rate of the extruded melt is unstable, and the product surface is prone to side wrinkles; 2. If the gap is to
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
