Wuxi Chengfeng Metal Technology Co., Ltd. has established itself as a leader in the manufacturing of high-quality cold rolled coils, catering to a wide array of industries. These coils are integral in various applications due to their unique properties and versatility. 
The production of cold rolled coils involves a meticulously planned process that ensures quality and consistency at every stage. The key steps are:
Shearing of Mother Coils The process begins with mother coils made from hot-rolled plates. These coils are cut to the required width and length using advanced shearing machines. This initial step is crucial for ensuring that the material is appropriately sized for subsequent processing.
Degreasing and Cleaning After shearing, the coils undergo a degreasing and cleaning process to remove oil, dirt, and other impurities from their surfaces. This cleaning is essential to enhance the quality of the final product, ensuring that surface contaminants do not affect the coating or further processing.
The cleaned coils are then annealed, a heating process that improves their plasticity and surface quality. Annealing is critical for enhancing the ductility of the metal, allowing it to be shaped more easily in later stages of manufacturing.
Cold Rolling Next, the annealed coils are fed into a cold rolling mill. This step involves a series of roller pressing and stretching processes, transforming the mother coils into thin plates or strips. The cold rolling process not only reduces the thickness of the coils but also enhances their mechanical properties.
Rust Removal and Polishing Following cold rolling, the products undergo rust removal and polishing treatments. These processes improve the surface finish and glossiness of the coils, making them more appealing and suitable for various applications.
Leveling The final step involves leveling the cold-rolled coils to achieve the required thickness and flatness. This ensures that the products meet precise specifications, which is crucial for quality control in manufacturing.
