Metal Stamping Die
Metal materials are relatively easy to process, and various types of processing methods can be used to produce stamping molds of various shapes to meet the needs of various products. There are various industries in which stamping dies are applied, such as automotive, aerospace, electronics, and consumer goods.
Stamping Die Maker
Stamping die maker mainly produce stamping dies. The application of die stamping in various important metal processing methods can efficiently and accurately manufacture a variety of metal parts, playing an important role in the industrial manufacturing industry.
In the custom stamping die process , it is necessary to select appropriate metal materials, design appropriate die structures, and strengthen stamping process parameters, so that the parts that can be manufactured have the advantages of high quality. The stamping process of dies can generally be divided into several processes, including metal stamping die design, material selection, stamping process analysis, die manufacturing, and actual stamping production.
Stamping die maker produce high-strength and high-precision stamping die, and the service life, performance, and manufacturing difficulty of the dies are closely related to the materials selected for the dies. There are various types of alloy tool steels commonly used in die materials, and alloy tool steels are mainly used. Due to their high hardness, strength, good wear resistance, thermal stability, and other characteristics, these materials are widely used.
Materials for Stamping Die
Carbon Tool Steel
Carbon tool steel is commonly used in Stamping die maker, such as T8A and T10A, which have the advantages of good processing performance and low cost. However, there are also shortcomings, such as poor hardenability and red hardness, large heat treatment deformation, and low load-bearing capacity.
Low Alloy Tool Steel
Low alloy tool steel is made by adding an appropriate amount of alloying elements based on carbon tool steel. Compared with carbon tool steel, it reduces quenching deformation and cracking tendency, increases steel hardenability, and has better wear resistance. Low alloy steels used for die manufacturing include Crwmn, 9MN2V, 7CRSIMNMOV (code CH-1), 6CRNISIMNMOV (code Gd), etc.
High Carbon and High Chromium Tool Steel
Common high carbon and high chromium tool steels include CR12 and CR12MOV CR12MO1V1 (code D2) has the characteristics of good hardenability, hardenability, and wear resistance. Heat treatment can cause very small deformation, making it a high wear-resistant micro deformation die steel with a load-bearing capacity second only to high-speed steel. Due to severe carbide segregation, it is necessary to implement repeated upsetting and drawing (axial and radial) to improve forging, which helps to reduce the unevenness of carbides and enhance their performance.
The Process of Stamping the Die
Many stamping die maker extensively produce die stamping, which plays a crucial role in modern industrial production and plays an important role in national defense and civil industrial production.
The die ensures the dimensional accuracy of the stamped parts and has the same characteristics, so the quality is stable and the interchangeability is good.
Ordinary presses can produce dozens of pieces per minute, while high-speed presses can produce hundreds to thousands of pieces per minute. So it is an efficient processing method.
Stamping processing is not like cutting processing, nor does it go through the step of heating.
By adopting die processing, parts with thin walls, lightweight, good rigidity, high surface quality, and complex shapes that cannot or are difficult to manufacture by other processing methods can be obtained.
Stamping and forming processing must have corresponding dies, which must be technology-intensive products. The manufactured workpieces are not in large batches, and their characteristics are difficult to process, high precision, high technical requirements, and high production costs. So, to achieve good economic benefits, the advantages of stamping forming processing can only be fully utilized when the production volume of stamped parts is large.

Test Stamping: To achieve a smooth production process, some sample stamping tests need to be carried out before formal production, paying attention to product quality and die performance.
The above are the main preparation steps before forming the stamping die, which need to be carefully prepared and inspected to ensure the smooth progress of the stamping production process, which helps to enhance production efficiency and product quality.
Stamping Die Structure
The stamping process of materials from deformation to separation can be divided into three steps:
Elastic Deformation Stage: Under the pressure of the punch, it can cause deformation of the material such as elastic compression, bending, and deep drawing.
Plastic Deformation Stage: After the elastic deformation stage, if the convex die continues to press down, it will cause the stress inside the material to reach the yield strength, causing plastic shear deformation of the material.
Fracture (separation) Stage: When the stress near the convex die reaches the material failure stress, a fracture occurs.
Unguided Single-process Die
The upper part of the punching die is composed of a die handle and a convex die, which is installed on the sliding block of the punching machine using the die handle. The lower die part is composed of a discharge plate, a guide ruler, a concave die, a lower die seat, and a positioning plate, which are installed on the punching machine workbench through the lower die seat. The upper and lower dies are mainly guided by the guide rails of the punching machine, and these two have no direct guiding relationship.
Guide Type Simple Punching Die
This type of die has the advantage of using the holes on the guide plate to guide the upper die through the convex die, and the guide plate also serves as the discharge plate. When working, the convex die always stays on the guide plate, which helps to improve the accuracy of the die’s guidance. Therefore, it is required that the stroke of the press used be smaller than the thickness of the guide plate. The upper die part mainly consists of a die handle, upper template, cushion plate, convex die fixing plate, and convex die. The lower part of the die mainly consists of a lower template concave die, a guide ruler, a guide plate, a return-type stopper pin, and a support plate.
The working process of this type of stamping die is as follows: the strip is fed along the support plate and the guide ruler is from right to left. The initial punching does not use a locking pin for long-term positioning. After this punching, the material is fed forward, and the overlapping edge passes over the movable blocking pin. Then, the strip is pulled in the opposite direction, so that the rear end face of the blocking pin is pressed against the overlapping edge of the strip for positioning, and the punch is lowered to complete the punching.
Guide Pillar Type Simple Punching Die
This punching die adopts a pair of guide pillars and guide sleeves to achieve precise guidance of the lower die. During the main operation of the stamping die, the strip material is correctly positioned using a guide ruler and a fixed stopper pin (also known as a positioning pin), which helps to ensure the same overlap value during punching. This punching die uses a rigid discharge plate to remove the waste clamped on the convex die. The punched workpiece is gradually subjected to natural material leakage through the top pressure of the convex die in the concave die hole.
Inverted Composite Die
An inverted composite die structure is a special type of die structure commonly used for stamping complex-shaped workpieces. Its basic structure includes the following parts:
- Upper Die (Convex Die): Installed at the lower part of the punching machine, opposite to traditional dies, used to support and apply pressure.
- Lower Die (Concave Die): Installed on the upper part of the punching machine, opposite to traditional dies, used to support and position workpieces.
- Auxiliary Die: mainly used as an auxiliary, used to support and assist in forming workpieces.
- Edge Cutting Dies: mainly used in the cutting tool part of the edge of the punching workpiece.
- Spring: helps the die maintain a closed state.
For stamping die maker, the design and manufacturing requirements for the inverted composite die structure are high, and it is necessary to consider the complex shape and size of the workpiece to improve the accuracy and stability of stamping processing. This structure generally plays an important role in the production of complex-shaped workpieces such as automotive parts and household appliance accessories, which can increase production efficiency and product quality.
