In recent years, due to the increase of the screw speed and the increase of the pressure in the barrel, it is mainly due to the addition of a large amount of filler during extrusion, which makes the wear resistance of the screw and barrel made of nitride steel appear to be relatively insufficient. I... Read More
The extruder screw and alloy barrel are the soul parts of the extruder, and their combination is related to the working quality of the extruder, the plasticizing capacity of the material, and the production efficiency. Therefore, when the screw and barrel of the extruder are severely worn, it will a... Read More
1. Look at the production process.High-quality screws need to go through multiple heat treatment processes, such as: quenching and tempering, tempering, qualitative, nitriding, etc., in order to meet the requirements of the screw. 2. Look at the R&D capabilities of the manufacturer. Companies wi... Read More
Today, let’s talk about parallel twin screws and how to choose parallel twin screws. Next, let’s take a look down with the editor and let’s understand. The spiral surface of the parallel twin screw is usually spray-welded with a unique formula of double alloy, which can effectively extend the servic... Read More
Repair of the barrel The inner surface of the barrel is harder than the screw, and its damage comes later than the screw. The scrap of the barrel is the increase in the inner diameter due to time wear. Its repair method is as follows: 1. For the barrel with increased diameter due to wear, if there i... Read More
