The manufacturer of Twin Bimetallic Screw and Barrel will show you how to repair the extruder barrel after it is worn out

The manufacturer of Twin Bimetallic Screw and Barrel tells you that the extruder barrel is a consumable part, but because its price is not cheap, many customers find that it is worn out, if the wear is not very serious, they will find a way to continue using it after repairing. Today the manufacturer of Twin Bimetallic Screw and Barrel will introduce how to repair it.

The manufacturer of Twin Bimetallic Screw and Barrel tells you that because the hardness of the inner surface of the extruder barrel is much higher than that of the screw, the damage and wear speed of the barrel is much slower than that of the screw. Most of the time, the barrel is damaged because of Under long-term wear, the inner diameter becomes larger.
For this situation, how do we fix it? The fix is ​​as follows:
1. The manufacturer of Twin Bimetallic Screw and Barrel tells you that when the diameter of the barrel is increased due to wear, if the nitriding layer on the surface still exists, at this time, the inner hole of the barrel can be directly bored and ground to a new diameter size. , Fine-cutting and replacing the old screw, the newly equipped screw should match the diameter of the barrel.
2. The manufacturer of Twin Bimetallic Screw and Barrel tells you that after processing and trimming the inner diameter of the barrel, recast the alloy. The size of the alloy should be controlled well and should be controlled within 1~2mm.
3. The manufacturer of Twin Bimetallic Screw and Barrel tells you that the abrasion parts of the extruder barrel are uneven, and the abrasion in the homogenization section is more serious. Therefore, the method of boring and trimming can be adopted in this section, and a nitriding alloy can be used. Steel bushing, the diameter of the internal control can be determined according to the diameter of the screw.
The manufacturer of Twin Bimetallic Screw and Barrel tells you that the screw and barrel are very important parts in the extruder. The screw is a slender threaded rod, and the barrel is a relatively small and long hole, but these two parts The production processes are relatively complicated, and wear occurs during use, and the method to be adopted or simply to replace new parts should be analyzed from a more economical point of view.
