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 die stamping, such as the high cost of making the tooling. Transfer die 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.

What Is Transfer Stamping?

You can use a process called transfer die stamping to make metal parts into precise shapes. In one process, each part passes through a different die. In this process, each part is independent.

In the first step, the part to be used must be cut from a continuous strip or sheet of metal. The parts are then moved from one place to another by means of special “fingers”. This automated process has a number of workstations to create complex design elements such as knurling, ribs or threads.

This method is unique in that it is highly accurate and can produce complex part shapes. This is why it is popular in making parts with complex features.

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 die 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 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 is different from other methods because the part is automatically moved from one process to the next. When the press is turned off, all the tools start their respective jobs on the metal plate at the same time. Afterward, the workpieces are transferred to the next process by means of a built-in conveyor.

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.

How Long Does the Transfer Stamping Process Take?

Typically, transfer die 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 die 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

Although metal stamping has many advantages, it also has some problems in production:

  • High initial cost: High cost of installation tools.
  • Tolerance problems: It is difficult to deal with tight standards.
  • Batch sizes: low cost for large batches, but high cost for small batches.

Disadvantages of Transfer Stamping

Transfer die stamping also has some disadvantages, such as:

  • High tooling costs: Transfer dies can be expensive.
  • Limited design flexibility: If the part design changes, expensive molds may need to be replaced.
  • Slower setup: because of the time it takes to prepare the mold for production.
  • Material waste: Scrap is generated when cutting molding from sheet metal.
  • Not suitable for small quantities: It is not suitable for small quantities, but it is very effective in making large quantities of items.

What Can Transfer Die Stamping Be Used For?

Transfer die stamping can be used in many areas, but it is most common in the metalworking and fabrication industries. Here are some examples of areas where transfer die stamping is used:

  • Automotive: Manufacturing chassis frames, structural components, and engine mounts.
  • Appliance manufacturing: Manufacturing parts for ovens, refrigerators, and washing machines.
  • Aerospace: Manufacturing parts such as stabilizers, elevators, rudders, flaps, and spoilers to ensure that flight control systems work accurately and last a long time.
  • Electrical and electronics: housings, plugs, and brackets for crafts.
  • Medical equipment: Manufacture precision parts for surgical tools and equipment.
  • Agriculture: components for agricultural equipment.
  • Energy: Manufacture parts for power generation and renewable energy.
  • General manufacturing: Can be used to make many different metal parts.

How Do I Choose A Transfer Stamping?

Transfer die stamping is not a good choice for small, simple or low-volume products. This is because it is too expensive to set up. If you need high precision, you should also consider other options.

However, it is excellent at quickly manufacturing large, robust, difficult parts and structural components. Because it works so quickly and effectively, a transfer die press is perfect for jobs that require the handling of shells and tubes.

What Materials Can Be Used For Transfer Die Stamping?

Transfer die pressing is a flexible manufacturing method that can also be used for materials other than metal. What you want the finished product to do will help you choose the right material. Here are some common materials used for transfer die stamping:

  • Metal: Metal is easy to form and bend and is the most commonly used material for stamping. Precious metals such as silver, gold, and platinum fall into this category. Also in this category are ferrous metals such as stainless steel, non-ferrous metals such as bronze, brass, and zinc, and non-standard alloys such as beryllium nickel and beryllium copper.
  • Paper: You can emboss on paper and use it for purposes such as artwork or packaging.
  • Leather: You can stamp designs on very fine leather.
  • Rubber: Gaskets, seals, etc. are made from cut rubber.

What Is The Future of the Use of Transfer Stamping?

Transfer die stamping technology will undergo many positive changes in the coming years. First of all, improvements in automation and robotics will make production more precise and efficient, thus reducing production costs.
