How to choose the screw of injection molding machine? For an injection molding machine, the screw is a very important component. In the operation of the equipment, it can play many roles, including melting, compacting, stirring, and applying pressure to the plastic. These processes require the use of all screws The rotation is completed in the barrel, so you must choose a good choice for this a
What are the factors that affect the plasticization of the barrel screw? The main factors affecting the plasticization quality of the barrel screw are: aspect ratio, compression ratio, back pressure, screw speed, barrel heating temperature, etc. 1. Length-diameter ratio: the ratio of the length of the screw to the diameter of the screw in the reasonable work of the screw. 2. Compr
How to improve the production efficiency of screw barrel The screw of the injection molding machine is an important part of the plasticizing part of the injection molding machine. The quality of the screw barrel is of vital importance for improving the quality and quantity of the products molded by the injection molding machine. How to improve the production efficiency of screw barrel
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
