How Transfer Die Stamping Works and What It’s Used For

Transfer die stamping is a versatile metal working method that is very important in the manufacturing industry. This method passes a metal part through several dies at the same time to form it into a very precise shape. In order to create very precise and complex parts, transfer die stamping requires the cooperation of several steps.

Transfer die stamping methods are heavily used in a variety of fields such as consumer electronics, automotive, and aerospace. This method is efficient, easily repeatable, and cost-effective. However, there are some problems with transfer stamping, such as the high cost of making the tooling. Transfer stamping may also not be the most cost-effective option for small production runs. This is because of their high first-time setup costs.

In the following article, we will discuss how transfer die stamping works, its uses, and its advantages and disadvantages.

Transfer Die Stamping Basics

Definition and Purpose

Transfer die stamping is a precise metalworking process. It uses the plastic deformation, cutting, and processing of metal strips or sheets to manufacture finished products. During this process, the metal material is moved through a number of stations or dies. The process therefore uses different dies, each of which performs a different task. For example, cutting, bending, or forming until the final part is produced.

Transfer stamping is a fast and efficient method of producing large quantities of complex, high-quality metal parts. By moving the material from one die station to the next, manufacturers can produce complex shapes and geometries with very tight tolerances. This ensures that all parts are identical and consistent.

Transfer stamping is a very precise process that can be used repeatedly and is suitable for mass production. It produces parts with complex shapes while maintaining quality and dimensional accuracy. This process is particularly suitable for producing large quantities of precise, identical parts. Examples include parts used in the aerospace, electronics, automotive, and household appliance industries.

Important Components Involved

Transfer die stamping is a precise metalworking method. It can be used to manufacture many identical complex metal parts. The principle is to move a metal strip or coil between the different stations of the die. Each station then processes the metal material differently. The aim is to cut, shape, or process the metal material to make the required part.

In most cases, the process consists of several main parts:

• Die: A die is a tool made up of two parts. It usually has cavities and shapes the metal. It has a number of stations, each of which is responsible for a different operation. For example, cutting, punching, bending, or forming.
• Conveyor System: The metal strip or coil is moved from one die to the next via a conveyor system. This system ensures that the metal is positioned and moved precisely for each operation.
• Feeder: This component feeds the metal strip or coil into the die. It then positions it correctly for the next step. The metal is thus reliably guided through the different stations.
• Punches and Dies: They are the main tools in the die station. Punches perform the cutting, punching, or forming operations. Dies provide the required shape and form.
• Press Machine: High-speed stamping presses are used in transfer die stamping. These presses provide the force required to complete the task. They are also equipped with devices for handling the rapid movements of the transfer system.

Thanks to these components, transfer die stamping can simultaneously process precision metal parts. As a result, it can produce metal parts for many industries very precisely and quickly.

How Does Transfer Die Stamping Work?

Transfer die stamping is most commonly used to manufacture parts in large quantities. As the raw sheet material passes through a series of dies, each die shapes the metal part until it reaches the desired final shape.

This method speeds up the process compared to conventional individual presses. This means that less work needs to be done manually. The three-axis transfer and the crossbar transfer are two transfer systems that allow for precise movement and ensure that production runs smoothly. The following are the detailed steps of the transfer die stamping process:

Preparing Materials

Prepare the raw materials needed, such as sheet metal, according to the finished product requirements. This includes ensuring that the sheet is of good quality and cut to the right size.

Designing and Manufacturing the Mould

A very important step is to manufacture the shape of the stamping mould. This involves making detailed plans showing the shape and requirements of the final part. Once the plans are in place, the moulds are carefully manufactured to ensure that the stamping process is correct.

Setting Up and Feeding

Once the material is ready, it is placed into the press. Setting up the press and the mould is also part of the workflow. The feeding system ensures that the sheet metal is always placed in the correct position.

Stamping Operation

The material is pushed into the mould holes under pressure. This process bends the metal into the shape of the die, giving the metal the desired characteristics. In transfer die stamping, different parts of the same press can be used for different tasks.

Part Ejection

After stamping is complete, the manufactured part is pushed out of the die. Depending on the settings, this process can be done manually or automatically.

Quality Check

To ensure that the stamped part complies with the standards and limitations. We need to carry out extensive quality checks on the stamped parts. This is an important step in identifying and correcting any errors or discrepancies.

Trimming and Other Operations

Additional steps may need to be performed in order to achieve the right size and shape of the stamped part. Examples include removing excess material or adding features through secondary operations.

Packing and Shipping

Once the parts are ready, they are packed and shipped. Proper packaging is important to ensure that no damage occurs during shipping.

Transfer die stamping is an efficient and accurate method of manufacturing parts. It allows for the production of uniform, high-quality parts in large quantities. Yonglihao Machinery has extensive experience in transfer die stamping. Please contact us if you have a need in this area.

Is Transfer Die Stamping the Same as Die Stamping?

Transfer die stamping and die stamping are not the same thing. Die stamping, sometimes referred to as “stamping,” uses a press to cut or form sheet metal into a specific shape or part. Usually, only one die is needed to cut or form the material in one pass.

On the other hand, in transfer stamping, different dies are used one after the other to make parts of more and more shapes. The workpiece moves from one die location to another. At each stage, the part undergoes some changes until it is finally molded.

How Long Does the Transfer Die Stamping Process Take?

Typically, transfer stamping can process up to 25 parts per minute. However, larger or more complex parts may take longer to process. The time required for this process depends on many factors, such as the complexity of the part, the size of the die, and the speed at which the transfer machine is operating.

The part must be moved from one mold to the next, which can take longer than expected. This is because there are usually only a few inches between each mold. For these reasons, the exact time required for a complete transfer die stamping can vary from a few seconds to a few minutes.

How Is Transfer Die Stamping Different From Other Types of Metal Stamping?

Transfer die stamping is one of the best ways to stamp metal. From the very beginning, it treats each part as an individual unit that is removed from the metal strip or sheet in the first step. This is different from the method of progressive die stamping.

Because of this, it can produce parts with complex designs such as threads and ribs. Transfer stamping can also be used to make deep-drawn parts because the die is not attached to the base metal strip. Because of this, transfer die stamping is a unique method for difficult and specialized metal stamping jobs.

Advantages of Transfer Die Stamping

Transfer die stamping is a fast and accurate method of processing sheet metal. It has many other advantages that make it a popular choice for many applications. Here are some of these key benefits:
