Copper clad aluminum coating process

Abstract

The invention discloses a copper clad aluminum coating process capable of ensuring the roundness of a core rod, reducing cost and shortening process. The process comprises the steps that unwinding, drawing, lubricating, straightening, rotary cutting of the aluminum core rod, copper strip unwinding and coated face roughening are carried out; a roughened copper strip and the rotary-cut aluminum rodenter the coating process together; in the coating process, the copper strip is repeatedly curled and deformed to form a copper reel which is close to the aluminum core rod, so that the aluminum corerod is completely wrapped in the copper reel; the joint of the copper reel is welded to form a copper clad aluminum wire; and finally, the copper clad aluminum wire is wound up on a reel. The coatingprocess eliminates the need to clean the aluminum core rod, is more environmentally friendly, and has the advantages of shortened process flow, reduced manufacturing cost and improved product qualityand yield.

AI Technical Summary

Benefits of technology

This technology allows for better coatings on an aluminium product without requiring any steps like washing or polishing them beforehand. It also improves the adhesion between layers by creating tiny recesses at specific locations along its length. Additionally, this method helps reduce costs while maintaining good performance over time.

Problems solved by technology

The technical problem addressed in this patented method for creating an insulating material on metal surfaces involves wasting time by removing excessive materials from the workpiece before applying another thin film or coatings thereover. This leads to increased costs due to longer production times and poor quality control measures that may lead to defects such as cracks caused when adding layers onto these metals.
