After extrusion, the freshly formed copper pipes undergo an annealing process to relieve internal stresses and enhance ductility. Annealing ovens use controlled heating and cooling cycles, ensuring that the pipes are soft enough for bending and installation. Once annealed, the pipes proceed to the tubing stage, where they are cut to length and undergo quality inspections. Sophisticated laser cutting machines are often utilized for their accuracy and speed, minimizing waste and maximizing efficiency.
Roller straightening machines are particularly popular in industries dealing with larger and thicker sheets. These machines use two or more rollers to apply pressure along the length of the sheet, gradually reshaping it into a flat plane. This method is often preferred due to its ability to handle heavy materials without compromising their structural integrity. For thinner sheets, mechanical straighteners can provide a more precise solution, utilizing a system of controlled bends and pressure points to achieve the desired flatness.
