How to prevent the barrel screw from being worn?If there is a difference in the expansion coefficient between the barrel and the screw, the gap between the screw and the barrel will change, causing damage to the barrel and the problem of screw bite.

The screw and barrel will wear due to the relatively hard and tough particles, so to avoid the wear of the barrel screw, you can coat the surface with a layer, or use a wear-resistant alloy as the raw material of the barrel screw.
It should be noted that the carbon content will have a certain effect on the hardness of the alloy. When the alloy is used as the raw material of the barrel screw, the steel material with carbon heat treatment will be used in the bottom layer.
The wear-resistant alloy in the barrel can reduce the speed of wear. In order to prevent the barrel screw from being corroded, injection and extrusion hot isostatic barrels can be used.
In order to reduce the wear of the barrel screw, pay attention to the size of the gap between the barrel and the screw during use. If the gap is too large, it should be reassembled. For the worn barrel, you can replace a bushing.
