The twin-screw extruder starts the heating process

In the process of starting the heating, the twin-screw extruder always turns on the temperature of several stages to start heating. Of course, this method is also relatively common, but this often happens after the temperature of the screw reaches a certain target. The temperature of the die has not yet reached (the steel of the die is relatively thick and the area is relatively large), so everyone usually keeps the screw under this condition, and then waits for the temperature of the die to gradually rise to the set temperature. Just start booting, this approach is more power-saving.

For twin-screw extruders, the heating and cooling systems are often removed first, and then the screw is pulled out as a whole. The split-type twin-screw does not need, just loosen a few bolts, turn the worm gear box handle device to lift the upper half of the barrel to open the entire barrel, and then carry out maintenance. This not only shortens the maintenance time, but also reduces the labor intensity. When making masterbatches, it is often necessary to change the color, if necessary to change the product, open the open processing area within a few minutes, and also analyze the mixing process by observing the melt profile over the entire screw. At present, when changing the color of the ordinary twin-screw extruder, it needs to use a large amount of cleaning material to clean the machine, which is time-consuming, power-consuming, and waste of raw materials.
