The Feature of Stamping

Advantage

Stamping production relies on dies and Machines. Compared with other metal production process, stamping has the following four features:

• Energy saving and material conservation
• Stable quality and precise dimensions.
• It allows for the production of parts with thin walls, light weight, good rigidity, high surface quality, and complex shapes
• High productivity, easy operation, and facilitates mechanization and automation.

Limit

This process also has some drawbacks, primarily related to noise and vibration during the stamping process. These issues are not solely caused by the stamping process or the dies themselves but are largely due to outdated traditional stamping equipment. Advancements in science and technology have gradually addressed these problems.

Metal stamping Process

Metal stamping is a manufacturing process where a metal sheet is placed in a stamping press that contains a die. The die is a specialized tool that shapes the metal into the desired form by applying pressure. The metal sheet is then cut, bent, or shaped into the desired design by the die. This process is often used to create large quantities of parts with high precision and consistency. Metal stamping is commonly used in various industries such as automotive, aerospace, electronics, and appliances to produce components like brackets, panels, enclosures, and more.

One of the key advantages of metal stamping is its ability to produce parts with tight tolerances and high repeatability. This makes it ideal for mass production scenarios where large quantities of identical parts need to be manufactured quickly and cost-effectively. Metal stamping can also help reduce material waste, as the process can be optimized to maximize the utilization of the metal sheet.

During the process of stamping, from material to final products, there are many steps. If you choose the single hit dies , there are many sets of dies. Currently, for big quantity metal parts, to save cost and effective production., many customer use Progressive Die Stampings to get lower cost and high speed of production .

The mainly metal stamping process are as follow,

• Blanking

Blanking is a metal stamping process that involves cutting a flat shape out of a metal sheet. In blanking, a specially designed die and punch set is used to cut the desired shape from the metal sheet, leaving behind the desired part known as a “blank.” This process is commonly used to create flat components such as washers, discs, and other simple shapes with precise dimensions. Blanking are often used as raw materials for subsequent forming processes or as standalone parts in various industries.

• Piercing

Piercing is a metalworking process that involves creating holes in a metal sheet or part using a specialized tool called a piercing punch. The piercing punch is forced through the metal sheet, removing a portion of material and creating a hole with a specific diameter and shape. Piercing is commonly used in metal fabrication to create openings for fasteners, connections, or ventilation in sheet metal components.

• Restriking

Restriking is a metalworking process that involves reusing a previously stamped part or blank to create a new component. In restriking, the existing part is placed back into the stamping press and subjected to additional forming operations using specialized tooling. This process allows manufacturers to modify or reshape existing parts without starting from scratch, reducing material waste and production time. Restriking is often used in situations where design changes or adjustments are needed after the initial stamping operation.

• Forming

The forming process is to directly duplicate and form the workblank or semi-finished workpiece according to the shape of convex and concave dies, and the die with local plastic deformation produced by the material itself is called forming die. The forming process can be divided into hole turning, expansion, necking, flaring, fluctuation forming and sizing, etc

• Flanging

Flanging is a metal stamping process that involves manipulating a metal sheet along its edge to create a curved or angled flange. This process is commonly used in metal fabrication to add strength, stiffness, or attachment points to a component. It can be done using specialized tools such as flanging dies or machines to achieve the desired shape and dimensions. It is a common technique in industries like automotive, aerospace, and HVAC for creating components with specific design requirements.

• Trimming

Trimming is a stamping process that involves cutting excess material from a metal part or component to achieve the final desired shape and size. It is often done after the initial stamping or forming process to remove any unwanted edges, burrs, or excess material left behind. Trimming can be performed using various tools such as shears, dies, or laser cutters to ensure precision and accuracy in the final product. This process is crucial in metal stamping and fabrication to produce high-quality components with tight tolerances.

• and so on

Stamping Dies

The tooling used in stamping is called stamping die, which is called die for short. Die is a special tool for batch processing of material (metal or non metal) into required blanking parts. Punching die is very important in stamping. Without qualified die, batch stamping is difficult to carry out. Without advanced dies, the advanced stamping process can’t be realized. Stamping process and die, stamping equipment and stamping material constitute the three elements of stamping, only by the combination of them can get the stamping parts at good quality and effective cost.

Metal Stamping Ability

We hereby wish to briefly introduce our production range for stamping, which will helpful for the reference of customer.

Equipment

The selection of stamping equipment is an important aspect of the design of the stamping process. It directly relates to the safety and rational use of the equipment, as well as the successful completion of the stamping process, product quality and precision, production efficiency, die life, material performance and specifications, and the associated costs.

In stamping production, various types of presses are used to meet different stamping requirements. There are many types of presses, which can be mainly divided into two categories: mechanical presses and hydraulic presses based on the different transmission methods. Mechanical presses are the most widely used in stamping production. With the development of modern stamping technology, high-speed presses, CNC turret presses, and other types are increasingly being widely used.

• CNC stamping/punching machine,
• Crank press,
• High-speed press,

Available material

The selection of materials  is intricately linked to the metal stamping and deep drawing processes, significantly influencing the design of the stamping process, the quality of stamped parts, the longevity of the product,  the effective production and manufacturing costs.
