Causes of delamination of aluminum rod extruded by continuous extruder

The causes of delamination of aluminum rod extruded by continuous extruder are as follows:

1, the surface of the ingot is stained with oil and dust, or the working part at the front end of the extrusion cylinder is worn, resulting in the accumulation of dirty metal around the elastic zone at the front end.

2. The layout of the die hole is unreasonable, too close to the simple inner wall of the extrusion cylinder.

3, extrusion cylinder, extrusion pad wear is too large or deformation.
