How to select the extruder?

The screw structure
Screw structure is the primary factor that affects the capacity of extruder.If there is no reasonable screw structure, it is not productive to simply raise the screw speed to increase the extrusion quantity and violate the objective law.
High speed and high efficiency screw design is built on high speed.The plasticizing effect of this kind of screw at low speed is worse, but the plasticization effect is improved gradually after the screw speed is improved, and the optimum result is reached when the design speed is achieved.At this time, both the high production capacity and the qualified plasticizing effect.
3. Cylinder structure
The improvement of the barrel structure is mainly to improve the temperature control of the feed section and set the feeding trough.The maximum length of this independent feed section is a water jacket, which is controlled by the advanced electric control device.
Whether the temperature of the water jacket is reasonable, it is very important for the stable work and efficient extrusion of the extruder.The temperature of the water jacket is too high, which will cause the raw material to soften too early, and even the surface of the raw material will melt and weaken the friction force between the material and the inner wall of the cylinder, thus reducing the extrusion thrust and the extrusion amount.However, the temperature can not be too low, and the low temperature of the cylinder will cause the screw to turn resistance too much, which will cause the motor starting difficulty or the rotational speed to be unstable when the motor’s carrying capacity is exceeded.With the innovative sensor and control technology, the water jacket of the extruder is monitored and controlled, and the water jacket temperature is automatically controlled within the optimum process parameters.
Machine of decelerate of 4.
Under the premise that the structure is basically the same, the manufacturing cost of the reducer is roughly proportional to its size and weight.Because of the shape and weight of the reducer, it means that there are more materials to be consumed in manufacturing, and the other bearings are larger, which will increase the manufacturing
