Quality Control in Metal Stamping Parts Production

Metal Stamping Parts are widely used in many fields such as electronics, automobiles, aerospace, and so on. With the rapid development of science and technology, the requirements for the precision and performance of stamping parts in various industries are also increasing. In order to obtain high-quality stamping products and considerable economic benefits in the fierce market competition, stamping manufacturers should strictly control the production quality of stamping parts from many aspects. Next, we will discuss in detail the quality standards of bending parts and drawing parts.

1. Requirements for bending parts
The shape of the Electrical Copper Stamping Parts should be as symmetrical as possible, so that the force is more uniform during the stamping process, which helps to ensure the bending accuracy and product quality. At the same time, the bending radius shall not be less than the minimum bending radius allowed by the material. If the bending radius is too small, the material is prone to cracking and other problems.

When bending perforated Red Copper Stamping Parts, the stress distribution at the bending part of the material changes due to the presence of holes, so special attention should be paid to prevent hole deformation. This requires optimization in mold design and stamping process, such as reasonably setting the gap and pressure of the mold.

If the bending edge is too short, it is difficult to form during the Copper Pressed Stamped Parts stamping process, and it is difficult to ensure the bending angle and dimensional accuracy. Therefore, generally, the straight part H of the bending edge is required to be greater than 2δ (δ is the material thickness). If H is very short in actual demand, an appropriate margin needs to be left to increase H, and the excess metal part can be cut off after bending and forming.

2. Requirements for drawing parts
The shape of the drawing part should be simple and symmetrical, which is conducive to uniform deformation of the material during the drawing process and reduces the occurrence of defects such as wrinkling and cracking. Moreover, the depth of the Copper Stamping Parts should not be too large. A shallower drawing depth can reduce the number of drawing times, facilitate forming, and also reduce the complexity of the mold and production costs.

Without increasing the process procedure, the fillet radius of the Precision Copper Stamping Parts shall not be increased at will. Because the increase in the fillet radius may change the flow state of the material, thus increasing the number of drawing times and subsequent shaping work, which will not only increase the number of molds, but also easily produce waste materials, and ultimately lead to an increase in cost.

In the process of Electrical Copper Stamping Parts processing, "man, machine, material, method, and environment" are the five key elements, among which the quality of "material", that is, raw materials, is crucial. When the quality of metal raw materials falls below standard, the production of stamping and drawing parts encounters numerous problems, which should be highly valued and prevented by stamping parts processing manufacturers.

Unqualified raw material thickness: If the thickness of the raw material exceeds the allowable tolerance range, during the stamping process, since the deformation of the material is closely related to the thickness, it may lead to a poor inner diameter of the stamping part, which cannot meet the design requirements. At the same time, uneven thickness may also cause uneven force on the mold during stamping, resulting in mold means galling, affecting the service life of the mold and the quality of subsequent products of Red Copper Stamping Parts.

Corrugation on the surface of the raw material plate: Corrugation on the surface of the raw material plate will make the material unevenly stressed during stamping and drawing, resulting in wrinkling of the Copper Pressed Stamped Parts, which seriously affects the appearance quality and service performance of the products.

Rust on the surface of raw materials: After the surface of raw materials is rusted, during the stamping process, the rust will transfer to the surface of the Copper Stamping Parts, resulting in rust on the manufactured stamping parts. This will not only reduce the corrosion resistance of the product, but also affect the appearance and market competitiveness of the product.

Pitting and shaking on the surface of raw materials: Defects such as pitting or shaking on the surface of raw materials will make the surface of the Precision Copper Stamping Parts uneven after forming, resulting in poor appearance, which will further affect the overall quality and use effect of the product.
