When manufacturing 304 Stainless Steel Forgings with complex shapes, ensuring dimensional accuracy requires comprehensive consideration of multiple factors.

First, accurate die design is the key. The shape and size of the die must fully match the requirements of the final forging, and the flow characteristics and shrinkage of the material during the forging process must be taken into account. By using advanced computer-aided design (CAD) and simulation software, the forging process can be simulated, the flow of the material can be predicted in advance, and the die structure can be optimized to reduce dimensional deviations.

Strict control of forging process parameters is essential. Including forging temperature, deformation speed, deformation degree, etc. Appropriate forging temperature can ensure that the material has good plasticity and is easy to form; reasonable deformation speed and deformation degree help to uniformly deform and avoid dimensional errors caused by local excessive deformation or insufficient deformation. The selection of high-precision forging equipment is also essential. Advanced forging equipment has better control accuracy and stability, and can accurately apply forging force and control stroke, thereby improving the dimensional accuracy of forgings.

During the forging process, a multi-pass, step-by-step forming method is adopted. The deformation amount of each pass is moderate, so that the material flows evenly and gradually approaches the final shape, which can reduce the internal stress and uneven deformation caused by excessive deformation at one time, thereby ensuring dimensional accuracy. In addition, timely and appropriate heat treatment of forgings after forging can eliminate internal stress, stabilize the organizational structure, and further improve the stability of dimensions.

Strict quality inspection is also an important link to ensure dimensional accuracy. Use high-precision measuring tools, such as three-coordinate measuring instruments, to conduct comprehensive inspections of the key dimensions of forgings, and timely discover and correct dimensional deviations.

For forgings with complex shapes, auxiliary processes such as local trimming and cold finishing can also be used to further process some parts that are difficult to achieve the accuracy requirements directly through forging to ensure that the overall dimensional accuracy meets the requirements. At the same time, strengthening the skills training of operators, making them familiar with the operation of forging processes and equipment, and being able to flexibly adjust process parameters according to actual conditions is also an important guarantee for improving dimensional accuracy.

In summary, through precise mold design, strict process control, advanced equipment, reasonable forming methods, effective heat treatment, strict testing and high-quality operators, it is possible to effectively ensure dimensional accuracy when manufacturing complex-shaped 304 Stainless Steel Forgings.
