Copper is cleaned to remove contamination from the surface. A high-precision monitoring system can help ensure this contamination is successfully removed, through automated inspection of the metal surface.
High-speed rolls need a reliable, verifiable automated solution to ensure defects are not introduced throughout the process. AMETEK Surface Vision products help reduce waste product.
The surface of the copper can be treated in preparation for a coating. This requires a very fine surface treatment for a low level of roughness.
Thin foils require cold rolling to reach the desired thickness and surface quality. They are more prone to surface damage than thicker metals, and so reliable monitoring is essential to the process.
This process uses rotary cutters to remove material from the surface of a piece of metal. This may introduce unwanted defects into the metal surface, so careful monitoring is required.
Pickling uses an acidic liquor to remove dirt, scale, rust and other contaminants from the surface of a metal. Surface inspection can verify the success of this process.
Scalpers remove surface impurities from copper ingots. They can also be used on edges to reduce trimming scrap. Accurate surface inspection systems can assess the quality of the scalping process.
Slitting coils can leave them prone to edge damage. AMETEK Surface Vision provides an advanced edge monitoring system, while also inspecting both sides of the slit metal strip.
Tension leveling lines are used to alleviate flatness defects in copper strips, creating a uniform tension across the strip. Surface defects may affect the success of this, so monitoring is important.
