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.
