From automobiles, electronics to aerospace, precision metal stamping has become the preferred manufacturing process for many industries with its high precision, high efficiency and low cost. What is a stamping part? What is precision metal stamping? How to customize stamping parts? This article will analyze the design and manufacturing process of metal stamping parts in detail, from concept conception to finished product delivery, and explore each key link in depth to help you better understand this field of precision manufacturing.


I. Concept and design: everything starts with creativity

1. Creative conception

The design of metal stamping parts begins with the creative conception stage. At this stage, product designers, engineers and stamping parts manufacturing experts need to work closely together to clarify the functional requirements, usage scenarios and performance indicators of the product. Through brainstorming and market research, the core value and innovation points of the product are determined to lay the foundation for subsequent design.

2. Application of CAD/CAE technology

Computer-aided design (CAD) and computer-aided engineering (CAE) are indispensable tools in modern design. Designers use CAD software to create three-dimensional models to accurately define the shape, size and structure of stampings. CAE technology is used to conduct virtual testing and simulation analysis of design models to evaluate their performance in actual use, such as strength, stiffness, and fatigue life. Through these technologies, the design team can optimize the design in a virtual environment and reduce the cost and time of physical prototype production.

3. Design optimization and iteration

The design is not achieved overnight, but requires multiple optimizations and iterations. Based on the results of the simulation analysis, the design team continuously adjusts the structure and size of the stamping parts to ensure that they have good stamping processability while meeting the functional requirements. For example, optimize the wall thickness of the stamping parts, the layout of the reinforcement ribs, and the stamping direction to reduce material waste and production costs during the stamping process.


II. Material selection: laying the foundation for stamping parts

1. The importance of material properties

Choosing the right material is the key to the successful manufacture of metal stamping parts. The physical and chemical properties of the material, such as strength, ductility, density, and corrosion resistance, directly affect the performance and service life of the stamping parts. For example, steel materials have high strength and good wear resistance, and are suitable for manufacturing stamping parts that need to withstand large loads; while aluminum alloys are the preferred materials for the aerospace and automotive industries due to their lightweight, high specific strength and good corrosion resistance.

2. Common metal materials and their applications

In the manufacture of metal stamping parts, common metal materials and their applications are as follows: steels (related materials include steel stamping parts) have high strength and good performance, and are widely used in automobiles, machinery, and construction industries; aluminum alloys are lightweight and corrosion-resistant, and are suitable for use in aerospace, automobiles, and electronic equipment; copper alloys (related materials include brass stamping parts) have good electrical and thermal conductivity and are used in the electronic and electrical fields; magnesium alloys are light in weight and have good shock absorption performance, and are often used in the automobile and electronic product housing industries. These materials have their own advantages and meet the needs of different industries.

3. Stamping performance of materials

When selecting materials, it is also necessary to consider their stamping properties, such as ductility and toughness. During the stamping process, the material needs to undergo plastic deformation under the action of the mold, and materials with insufficient ductility and toughness are prone to cracking or breaking during the stamping process. Therefore, designers need to select materials with suitable stamping properties according to the shape and size requirements of stamping parts.


III. Precision metal stamping and die design: the core link of manufacturing

1. Overview of precision metal stamping

Precision metal stamping is an efficient metal processing technology that uses the die to deform the metal sheet under the action of the press to produce stamping parts of various shapes and sizes. The stamping process mainly includes various processing methods such as blanking, bending, stretching and forming. The choice of each process depends on the shape complexity and precision requirements of the stamping part.

The blanking process is mainly used for material separation, such as punching and blanking. The key lies in the design of the die edge and the control of the blanking force to ensure the quality and flatness of the section after blanking. The bending process is used to manufacture stamping parts with bent shapes. The difficulty lies in controlling the bending radius and the amount of springback to ensure the dimensional accuracy and shape stability of the stamping parts.

The stretching process is used to manufacture stamping parts with complex curved surfaces. The key lies in controlling the deformation degree and stress distribution of the sheet to prevent wrinkling and cracking. The forming process is more complicated, and can process metal sheets into various complex three-dimensional shapes, such as bulging, flanging, shrinking, etc., which requires comprehensive consideration of factors such as material properties, mold design and process parameters.

The diversity and efficiency of precision metal stamping have made it widely used in automobile manufacturing, aerospace, electronics and electrical appliances and other fields. Stamping parts are the core strength of manufacturing industry. By reasonably selecting precision metal stamping, it can effectively improve production efficiency and reduce production costs, while ensuring the quality and performance of stamping parts, and meet the strict requirements of metal processing in different industries.

2. Key elements of mold design

The mold is the core tool of precision metal stamping, and its design and manufacturing accuracy directly determine the quality and production efficiency of stamping parts. In the mold design process, there are several key elements that need to be considered. First, the structural design of the mold is crucial. It includes the precise design of the upper and lower molds, as well as the guiding, positioning and supporting structures of the mold. These parts work together to ensure that the mold can work stably and efficiently during the stamping process.

Secondly, the accuracy of the mold is the basis for ensuring the quality of stamping parts, which directly affects the dimensional accuracy, shape accuracy and surface quality of stamping parts. The dimensional accuracy and shape accuracy of the mold must strictly meet the design requirements of the stamping parts. During the design process, high-precision measuring equipment and design software are required to accurately design and measure the mold surface size, shape tolerance, position tolerance, etc.

The mold surface accuracy needs to be processed by high-precision CNC processing equipment (such as CNC milling machines), and polished and ground to improve the surface quality. The dimensional accuracy of the mold needs to be achieved through strict design and processing control, while considering factors such as processing errors, assembly errors, and wear during the stamping process. By adopting advanced manufacturing processes (such as CNC machining, EDM, laser machining) and strict heat treatment and surface treatment, the accuracy and service life of the mold can be effectively improved.

3. Mold manufacturing and processing

The manufacturing of the mold is an important link in the stamping process, and its manufacturing accuracy and quality directly affect the service life of the mold and the quality of the stamping parts. Mold manufacturing usually uses high-precision CNC processing equipment (such as CNC milling machines and CNC wire cutting machines) to ensure the dimensional accuracy and shape accuracy of the mold. After processing, the mold also needs to undergo heat treatment, surface treatment and other processes to improve its hardness and wear resistance. Finally, through the precise assembly process, the various parts of the mold are assembled into a complete mold system.

During the mold manufacturing process, CNC machining equipment can achieve high-precision machining of complex surfaces and improve the processing efficiency and quality of the mold. Heat treatment process is used to improve the hardness and wear resistance of the mold and extend the service life of the mold. Surface treatment processes (such as polishing and coating) can further improve the surface quality and corrosion resistance of the mold. Precision assembly process ensures that the various parts of the mold can fit closely to form a stable and efficient mold system.

By optimizing mold design, manufacturing and processing technology, the accuracy and service life of the mold can be effectively improved, production costs can be reduced, and the quality and production efficiency of stamping parts can be improved. This is of great significance to the development of modern manufacturing industry.
