Largest Metal Stamping Companies in China

There are many classification methods for die stamping parts, which can be divided into ordinary materials, low-alloy high-strength structural steel (HRB400), stainless steel metal composite materials (HRC60) and low-alloy steel according to the material. According to the shape of stamping parts, it can be divided into sheet metal stamping parts and parts stamping parts. Stamping parts are used to process parts of various shapes and sizes, and are mainly used in industries such as automobiles, machinery manufacturing, aerospace, and home appliances. The stamping process can be divided into stamping dies and forging dies according to the stamping dies.

1. General stamping parts are composed of various factors such as mold material, die structure and molding process, such as material hardness, wear resistance, etc., to ensure the performance of the product.

Die design should take into account the following factors: material and structural properties of stamping parts; shape parameters of stamping parts; stamping process parameters. If the material, structure, mold design, etc. are unreasonable, the product will not be able to meet the required performance, and the dimensional stability of the product after use cannot be guaranteed. Therefore, reasonable design of mold material, blanking structure and forming process can ensure the performance of the product. According to different materials and different requirements, targeted mold materials and punching techniques can be made to ensure the normal performance of the product.

2. Stamping process

The main feature of the forming process is that the stamping process is a continuous process. After the stamping parts are obtained from the material, because the residence time in the mold is very short, a stamping machine is needed to manufacture the stamping parts. The stamping process has great flexibility, and there are dozens of forming methods, making its manufacturing cost very low. Therefore, stamping parts are generally formed by rapid stamping, hot pressing and other methods. The general mold stamping process can be divided into six stages: preparation → heating → cold pressing → punch cold stamping → cutting → cooling → discharging → assembly. as the picture shows.

3. Raw materials for stamping parts

The raw materials used for stamping parts generally include carbon steel, alloy steel, stainless steel, copper, aluminum, magnesium, nickel, iron, molybdenum, titanium, tungsten, chromium, etc. These materials have high hardness, good wear resistance, and are easy to cut. In addition, other alloys such as iron and titanium are used, either by casting or stamping processes.

4. Requirements for stamping processing on the dimensional accuracy and surface quality of the workpiece

Stamping parts have relatively high dimensional accuracy requirements during use. For example, for workpieces of different sizes, different angles and different cross-sectional sizes, it is necessary to ensure that there is no difference between them, which requires processing personnel to have high precision. Therefore, in the processing process, the processing accuracy must be strictly controlled. In addition, due to the presence of many impurities in stamping parts, such as rust, dirt, etc., it is easy to cause pitting, pores and other defects on the surface. Therefore, the surface of stamping parts is required to be rough, and no obvious pores, cracks, oil stains, rust, rust spots, etc. are allowed.

5. The influence of material properties on the dimensional accuracy and surface quality of stamping parts

The hardness of sheet metal stamping parts is larger than that of steel plate stamping parts, so steel plate stamping parts have better precision. The hardness of steel stamping parts is closely related to the precision of steel stamping parts. The higher the hardness, the better the strength and toughness of the sheet metal. Generally speaking, the higher the hardness of the sheet metal, the higher its hardness value, which means that the strength of sheet metal stamping parts will be higher. The high hardness of steel stamping parts is due to the high quality of steel stamping parts. Steel stamping parts are very precise parts with good surface quality and high dimensional accuracy requirements. Therefore, steel stamping parts are required to have good technical performance.
