cause:

The defects such as pits, scars, triangle cracks, and slag inclusions on the surface of the single wire are mainly caused by the material. Of course, the surface of the wire core is cracked, and it is not excluded that the wire drawing die hole type is unreasonable. Analysis of the situation. The grooving on the surface of the core is continuous, which is generally caused by the wire drawing. The lubricating conditions of the wire are deteriorated and the surface is sticked to aluminum. The grooving that is not continuous may be caused by sticking foreign objects to the strand die.

solution:

For grooving of aluminum wire when pulling the wire, first check whether the lubricating effect of the wire can meet the requirements of the wire. You need to replace the lubricating oil in time, replace the wire mold, or remove the debris stuck on the wire mold. The incoming wire should be eliminated in time, and the crimping die should be checked for damage and debris, and repaired and replaced in time.
