Description
Sheet Metal Forging is a process that plastically deforms metal sheets under specific temperature and pressure conditions. It is a combination of bulk forming and sheet metal forming technology. This process usually uses dies and equipment to stamp or extrude metal sheets so that the material can obtain the desired geometry and mechanical properties under controlled deformation. Sheet Metal Forging can be carried out under hot or cold conditions, depending on the type of material, thickness and product design requirements. Through forging, the internal structure of the metal is denser, and the fiber streamlines are distributed along the contour of the workpiece, which helps to improve the overall structural stability and fatigue strength.
Features
Improved material density and enhanced mechanical properties
Sheet metal forging applies high pressure to metal sheets, causing plastic deformation and rearrangement of grains, thereby improving material density. The tensile strength of forged parts is about 15%-30% higher than that of cast parts, and the fatigue life is increased by more than 40%. This organizational optimization reduces internal defects such as pores and inclusions, improves overall strength and toughness, and is suitable for the manufacture of key parts that withstand high stress.
Precise dimensional control reduces the need for subsequent processing
Die accuracy during the forging process directly determines the dimensional stability of the parts, and modern CNC forging equipment can achieve a tolerance control of ±0.05 mm. High precision improves part dimensional consistency, reduces the amount of machining, and shortens processing time and cost. For example, sheet metal forging can reduce subsequent machining processes by 20%-30%, improve production efficiency and reduce scrap rates.
High material utilization and cost-effectiveness
Compared with traditional processes such as mechanical cutting, sheet metal forging can maximize the use of original plates and reduce material waste by up to 25%. Through cold forging or hot forging process, the sheet metal is directly formed, with less scrap and can be recycled and reused, reducing the cost of raw materials. This feature directly translates into cost advantages and resource conservation in large-scale production.
Short production cycle and strong adaptability to mass production
Once the forging die is designed, it can be quickly reused, and the production cycle is greatly shortened. Compared with casting and machining, the forming time of a single piece of sheet metal forging is shortened by about 40%. The die replacement and adjustment are flexible to meet the needs of different batches, ensuring dimensional stability and product consistency in mass production, and meeting the high standards of the automotive, aviation and other industries.
