Some Quality Control Principles (QCP) of precision stamping parts

SCZY LTD will produce not only Investment Casting Parts, Forging Parts, Die Casting Products, but also Stamping Parts. Today we are going to talk some quality control principles of Precision Stamping parts. Now let's do it. As it is known to all, with the development of industry, precision stamping parts are widely used in household appliances, auto parts, decorative materials and other industries. In order to meet the requirements of use, the quality requirements of precision stamping parts are getting higher and higher, and its quality control management is also stricter. The following is an introduction to the quality control principles of precision stamping parts.

1. Precision principle: The number of processes of drawing parts is related to material properties, drawing height, number of drawing steps, drawing diameter, material thickness and other conditions, which can only be determined by drawing process calculation.
2. Fine principle: The number of processes of the bending part mainly depends on the complexity of its structure and shape, and it needs to be determined according to the number of bending angles, relative positions and bending directions.
3. The principle of exquisiteness: when the section quality and dimensional accuracy of the stamping parts are required to be high, it can be considered to add a trimming process after the blanking process or directly use the precision blanking process.
4. Precise principle: When blanking workpieces with simple shapes, it can be completed with a single-process mold. When blanking workpieces with complex shapes, due to the limitation of the structure or strength of the mold, the inner and outer contours should be divided into several parts for blanking. Multiple Metal Stamping processes are required. If necessary, continuous mode can be used. For workpieces with high flatness requirements, a leveling process can be added after the blanking process to accurately incorporate the characteristics of each product into the production process.

5. Quality principle: In order to ensure the quality of Precision Metal Stamping Parts and improve the stability of the metal stamping process, it is sometimes necessary to increase the number of processes. For example, additional positioning process hole punching of bending parts, increased deformation reduction hole punching in the forming process to transfer the deformation area, etc., to ensure that each product is precise, fine and exquisite.
All in all, the craftsmanship of precision stamping parts is directly related to the difficulty of processing parts, the quality of products, labor efficiency and economic benefits. Therefore, in the process of precision stamping parts, it is necessary to strictly abide by the quality control principles to ensure that the quality of each product.
