Wie der Schraubenzylinder innovativ eingesetzt werden sollte
After the screw barrel is used for a period of time, the screw edge and the nitriding layer of the barrel (when making a new screw, both the screw and barrel will stop the nitriding heat treatment, so there will be about 30-60 silk oxide layers on the surface 2) when worn in both directions, the gap between the two sides increases, causing partial backflow of the plastic, and the…
Wie lässt sich das Problem der Biegeverformung bei der Extrusion von Produkten lösen?
The bending deformation of PVC profile is a common problem in the extrusion process. The main reasons are: uneven discharge of the die; insufficient cooling of the material during cooling and shaping, and inconsistent shrinkage; equipment and other factors.It is recommended to solve from the following aspects:1. Ensure the concentricity and levelness of the entire extruder line, and correct the concentricity and levelness of the extruder, die, shaping die, water…
Welche Reinigungsmethoden gibt es für die Extruderschnecke?
