The precision stamping parts processed by precision stamping technology has the advantages of the large size range, complex shapes, and high precision, and are widely used in the automotive, medical, aviation and other industries. The processing technology of precision stamping parts is relatively complicated. To ensure the molding effect of stamping parts, the following process matters need to be paid attention to when processing precision stamping parts:

　　1. The number of processes of precision stamping parts mainly depends on the complexity of its structural shape, and it depends on the number of bending angles, relative positions, and bending directions. When the bending radius of the bending part is less than the allowable value, a shaping process is added after the bending.

　　2. The number of processes of precision stamping parts is related to the material properties, drawing height, several drawing steps, drawing diameter, material thickness, and other conditions, which can be determined after drawing process calculation. When the rounded corner radius of the drawn part is small or the dimensional accuracy is required, a shaping process is required after drawing.

　　3. The determination of the number of procedures should also be by the existing mold making capabilities and the status of the stamping equipment of the enterprise. The mold-making ability should be able to guarantee the corresponding improvement on mold processing and assembly accuracy. Otherwise, you can only increase the number of operations.

　　4. When the cross-section quality and dimensional accuracy of precision stamped parts are high, you can consider adding a trimming process after the blanking process or directly using a precision blanking process.
