What do you need to pay attention to when choosing a precision stamping parts processing plant [hardware]

Customers often ask how to find a better precision stamping parts processing factory. The author summarizes the following points and hopes to provide some help to customers who are looking for precision stamping parts processing factories. The precision stamping parts processed by precision stamping technology have the advantages of large size range, complex shape, and high precision. They are widely used in the automotive, medical, aviation and other industries. However, the processing technology of precision stamping parts is more complicated. If you want to ensure the forming effect of stamping parts, you need to pay attention to the following matters when processing precision stamping parts: 1. The number of processes of precision stamping parts mainly depends on the complexity of its structure and shape. It depends on the number of angles, relative position and bending direction. When the bending radius of the bending piece is less than the allowable value, a reshaping process is added after bending. 2. The number of processes of precision stamping parts is related to the material properties, drawing height, number of drawing steps, drawing diameter, material thickness and other conditions, which can be determined by drawing process calculations. When the rounded corner radius of the drawn part is small or the dimensional accuracy is required to be high, it is necessary to add a shaping process after drawing. 3. The determination of the number of processes should also conform to the company's existing mold making capabilities and the status of stamping equipment. The mold making ability should be able to ensure the corresponding increase in mold processing and assembly accuracy. Otherwise, the number of processes can only be increased. 4. When the cross-sectional quality and dimensional accuracy of precision stamping parts are required to be high, consider adding a trimming process after the punching process or directly adopting a precision blanking process. 5. In order to improve the stability of the precision stamping process, it is sometimes necessary to increase the number of processes to ensure the quality of precision stamping parts. For example, the additional positioning process hole punching of the bending part, the deformation-reducing hole punching in the forming process to transfer the deformation zone and so on. 6. The precision stamping parts with simple shapes are punched out by a single-process mold. For workpieces with complex shapes, the inner and outer contours of the mold should be divided into several parts due to the restriction of the structure or strength of the mold, which requires multiple stamping processes. 7. Precision stamping parts processing plants should use special stamping processing oil. Non-special oils such as rapeseed oil, machine oil, and recycled oil do not contain additives suitable for stamping processing, which will cause the accuracy of the workpiece to decrease, and the burrs will be fluff , Quality problems such as surface pothole damage. In addition, the chemical substances in non-special oil products can cause the machine to rust and yellow robe, and workers' skin allergies.
