Stamping Processing

Stamping processing is a metal cold deformation processing method that utilizes the power of conventional or specialized stamping equipment to directly deform the sheet metal in the mold, thereby obtaining product parts with a certain shape, size, and performance. 

The following is a detailed explanation about stamping processing:

1、 Basic principles

The basic principle of stamping processing is to use stamping force to apply pressure to the material through a mold, causing it to undergo plastic deformation such as bending, strEtching, shearing, etc., in order to obtain the desired shape and size of the workpiece.

2、 Three elements

Sheet metal, mold, and equipment are the three essential elements of stamping processing. Among them, the mold is a key component in stamping processing, which determines the shape and dimensional accuracy of the stamped parts.

3、 Characteristics

Stable quality: Due to the fact that the mold ensures the dimensional and shape accuracy of the stamped parts, and generally does not damage the surface quality of the stamped parts, and the lifespan of the mold is generally long, the quality of stamping is stable and interchangeable.

Wide processing range: Stamping can process parts with a large size range and complex shapes, such as small stopwatches for clocks, large car longitudinal beams, covers, etc.

High material utilization rate: Stamping generally does not generate chips or debris, consumes less material, and does not require other heating equipment, making it a material saving and energy-saving processing method, and the cost of stamping parts is relatively low.

High production efficiency: Stamping processing can complete the processing of a large number of parts in a short period of time, improving production efficiency.

Metal stamping die

Metal stamping dies are tools used for metal stamping processing, which can process metal sheets into the desired shape and size through stamping, shearing, forming, and other methods. This type of mold plays a crucial role in the manufacturing industry, especially in the component manufacturing process of industries such as automotive, home appliances, electronics, and aerospace. The manufacturing process of metal stamping molds includes multiple steps such as design, processing, Assembly, debugging, and maintenance. In the design phase, computer-aided design (CAD) software is usually used to create a three-dimensional model of the mold and conduct simulation analysis to ensure the feasibility and efficiency of the design.

Sheet metal stamping dies

Sheet metal stamping dies are specialized molds used for stamping and processing sheet metal materials. Sheet metal materials usually refer to thin metal sheets, such as steel plates, aluminum plates, etc. There are many types of sheet metal stamping molds, which can be divided into punching molds, bending molds, deep drawing molds, forming molds, etc. according to the shape and structural characteristics of stamping parts. These molds play a crucial role in the sheet metal processing, enabling efficient production of sheet metal parts of various shapes and sizes.

Metal punch press dies

The metal punch press dies is an accessory corresponding to the punch press, and the workpiece undergoes plastic deformation under the combined action of the punch press and the resistance of the mold to complete the processing process. The precision of punch molds largely determines the machining accuracy of workpieces. Punch press molds are usually composed of top rods, top plates, gear rings, limit sleeves, limit columns, positioning pins (plates), punch press fixing plates, fixed discharge plates, fixed stop pins (plates), unloaders, discharge plates, and other components. These components play their respective roles in the mold, jointly ensuring the smooth progress of stamping processing.

Precision stamping dies

Precision stamping dies is a type of mold used in industrial production to shape metal materials into desired parts or products using various stamping machines and commonly used tools mounted on stamping machines according to working pressure. This type of mold is usually used to produce high-precision, high-quality stamped parts, such as electronic components, automotive parts, etc. The manufacturing process of precision stamping molds has high requirements for materials and processes, requiring the use of advanced processing technology and high-precision equipment to ensure the accuracy and performance of the molds.

Prototype stamping dies

Prototype stamping dies usually refer to stamping dies used for producing product prototypes. In the process of product development, prototype molds play a crucial role in helping designers and engineers verify the feasibility and performance of product design. The product prototype produced through prototype molds can undergo various tests and evaluations to improve and optimize the design. The manufacturing process of prototype stamping molds is usually flexible and can be customized according to specific needs.
