There are significant differences in the processing methods between aluminum forgings and steel forgings. Due to its higher hardness and lower plasticity, steel forgings require more complex processing methods and equipment, such as CNC machining centers and universal grinding machines. The final shape and specifications of steel forgings are achieved through multiple processing steps such as cold punching, hot treatment, and quenching. The difficulty of controlling these steps is high, and the manufacturing time is long. However, steel forgings produced in this way have higher strength, corrosion resistance, and longer service life.
Case: In order to manufacture a batch of large forging machine bases, a company imported dozens of professional equipment such as CNC machining centers and grinding machines from abroad and provided strict training for processing personnel. Although the processing cost increased by more than 20% as a result, the high-quality products were recognized by customers.
On the other hand, the manufacturing of aluminum forgings uses simpler and more efficient methods. Aluminum alloy has high plasticity and thermal conductivity and can form the final product shape in one-time processing, so there is no need for complex production processes like steel forgings. Generally, only a few processes such as cold extrusion, hot extrusion, and roll forming are used in the production of aluminum forgings. These processes only take one pass to complete the forming process and will not cause significant changes in material properties, which ensures the stability of product performance.
Case: A certain company used advanced multi-column CNC extrusion equipment to perform extrusion processing of aluminum alloy, eliminating pre-treatment such as removing the surface oxide layer of the raw materials. This improved production efficiency, reduced time and cost expenses, and also ensured product dimensional accuracy and stability.
In conclusion, aluminum forgings and steel forgings have significant differences in processing methods, which also give them different characteristics and advantages in terms of production cost, output, production cycle, and product performance. Manufacturers need to choose the most suitable processing method according to demand and material characteristics to obtain higher production efficiency and quality assurance.
