A custom metal stamping die is a piece of equipment that’s absolutely unique. One thing is all it stencils. It is inserted in stamping presses to punch and bend sheets of metal. Thus, this process helps us increase the production rate of identical parts rapidly.
The entire issue of metal stamping is all you would need here. Among the contents of this article, we will mention the types of dies and their designs. You will also have a good grasp of the cost of the dies and the company you should hire just for your project.
Metal Stamping Dies: A Primer on Custom Metal Stamping Die
Custom metal stamping die is a metal stamping tool. It is the tool that does the stamping. You can make better parts by understanding this technology. Stamping dies are the main components of metal stamping, so understanding their use is a good start.
Working Principle of Stamping Die
A stamping die is a tool that represents an image of what you want. It is fixed on a machine, which is called a stamping press. The press uses a huge force that comes from the hydraulic system. This force is transmitted to the die that moves through the sheets. It either separates or bends the metal as per your selection.
Standard vs. Custom Dies
A standard die produces the same geometries. For instance, a simple washer or L-bracket is included. A custom die is much more than that. An engineer has to design the die for that specific application. Suppose your design is innovative or intricate; a custom die is the best option.
Why Tooling with Custom Dies is an Effective Option?
The use of custom dies has several advantages. The parts which are made with them are of better quality, more uniform, and they are produced faster and more economically. In addition, the production processup is entirely different because the unique parts that you create will not be able to be reverse-engineered easily. Making high-volume quantities by a good-quality die is a wise choice.
Types of Custom Metal Stamping Dies: Which One Is the Best for Your Project?
The die type that you are going to use for your project depends on some factors. You need to consider the shape, the quantity you need, and the available budget. In some cases, particular die types are suited for certain jobs.
We can get an idea of the use of some standard types of Custom Metal Stamping Dies & Sheet Metal Press Die Solutions by analyzing their characteristics. Every die type has its unique advantages. Selecting the most suitable one is crucial to efficient production.
| Die Type (H3) | Description | Best For | Pros | Cons |
|---|---|---|---|---|
| Progressive Die | The metal strip moves through many stations in the die. Each station performs one operation (cutting, bending, etc.). | High-volume, complex parts with multiple features. | Very fast and efficient for mass production. Low cost per part. | High initial cost to build. Complex design. |
| Compound Die | Makes multiple cuts or punches in one press stroke. | High-accuracy, flatter, and simpler parts like washers or blanks. | Excellent accuracy and flatness. Lower tool cost than progressive. | Slower production speed. Not for complex forming. |
| Transfer Die | The part removes from the metal strip in the early stage. A mechanical system moves it then from station to station. | Large parts needing several press operations and that are too big for a progressive die. | Very versatile for large or deep-drawn parts. | Slower than progressive dies. The transfer system adds complexity. |
| Combination Die | Combines a cutting operation with a non-cutting (forming or drawing) operation in one stroke. | Parts that need both cutting and forming, to reduce the process steps. | Reduces the number of machines or setups needed. | Can be limited to simpler part shapes. |
Creating a Custom Die: The Journey from the Idea to Production
The building of a custom die is not a very easy task. It is the process that translates your idea into the actual tool. It requires a well-laid plan and the best skills from experts. Online materials will be helpful to understand How the Metal Stamping Process Works and manage your project.
Step 1: Discussion and Feasibility Evaluation of the Design
The initial stage is a discussion between your company and us. We look over your part design that is usually a 3D CAD file. We verify the suitability of the design for stamping. We also talk about the material choice and your production goals to ensure successful completion.
Step 2: Die Engineering and 3D Modeling
Mechanical engineers at our company use specialized software to design these custom metal stamping dies. They produce a complete 3D model of the tool. This involves running tests to check metal flow and blank forming. This helps us avoid problems before we construct the die.
Step 3: Selection of the Right Material
Die material is very significant. It determines how long the die lasts. D2 and A2 tool steels are common materials. They are tough, and yet resistant to wear. We may use carbide tool steel for long production runs because of its extreme hardness.
Step 4: Precision Machining & Assembly
Next, we assemble the die. Each part is manufactured with the utmost precision using high-quality machines. The methods we use include grinding, wire EDM, and CNC turning services with high precision. This guarantees that all parts will be assembled and manufactured to an exact size.
Step 5: Testing, Prototyping, and First Article Inspection (FAI)
After assembling the die, we test it. It is placed in a press machine; then, the first sample parts are produced. We measure these parts to ensure they meet your specific requirements. This quality check is known as the First Article Inspection or FAI. When you give your approval, we will start with the full production.
The Factors That Shape Your Custom Die Design
A few important factors make the design of a custom die distinct. Offsetting this information to your manufacturing partner will ensure that the tool you receive is according to your precise specifications. It will also save you time by giving you an accurate quote.
Part Shape and Complexity
The shape of your part is a decisive factor. Elements such as deep draws, tight corners, and many bends are the ones that will complicate the die. A more complicated item will require an advanced and more expensive die design.
Sheet Metal Material & Thickness
The sheet metal material used is important. Metals such as steel, aluminum, and brass form differently. Thicker or stronger materials require a stronger die and more force during pressing. The die must also have the right clearance to accommodate the thickness of the metal.
Required Tolerances & Precision
Tolerances are the limits of acceptable variations in a state. In the event that your part requires much tighter tolerances, precision building in the die is required. Achieving this very tight tolerances on small features may require part-specific tooling. At times, we achieve this through advanced techniques such as Swiss CNC turning services.
Expected Production Volume & Die Lifespan
How many pieces are you planning to manufacture? A die for 10,000 parts is very different from one that is for 1,000,000. For high-volume production, a more durable custom metal stamping die is used. These dies are the ones that mostly cost more and are built from high-grade materials.
Press Specifications
In most cases, the die should be fit to the machine dies, or it won’t work. We need some info about the machine, which includes power (tonnage), bed size, and shut height. The design of the die is done in conjunction with the proposed machine to ensure effectiveness and safety.
Grasping the Cost and ROI of a Custom Metal Stamping Die
The price of a custom die is a significant aspect. Nevertheless, it is an investment that is going to benefit you in the long run. This is more-so in terms of high-volume production.
What Are the Specific Factors that Initially Impact Tooling Costs?
There are variables that will affect setting the initial tooling cost. These are the factors.
- Tool Complexity: Example; progressive dies containing many stations will cost more than simple compound dies.
- Tool Size: A larger die requires more material and machining time. Thus, it increases the cost.
- Tool Steel/Carbide Grade: Premium quality materials that are more durable will cost more.
- Time Span and Tolerance Required: Grades are out of dies that are built for millon cycles and tight tolerances, so costs are more for a run with a low cycle count.
Balancing Tooling Cost vs. Per-Piece Price
There exists a balancing act between the rates for initial tooling and the expense of each part. Efficient tools with a high initial cost may lead to low per-part price. This understanding is the basis for the return on investment (ROI).
For instance, a complicated progressive die may cost as much as $50,000 or $100,000, while it can help reduce the component price from $1.50 (with simpler tooling) to just $0.20. The previos example shows that even the expensive custom dies are incredibly profitable in the case of mass production runs of 100,000 units or more.
Choosing the Partner for Your Custom Stamping Die
It is as critical to choosing the right partner as it is to designing a die. The cooperation with a good supplier is the key to the success of your project.
Major Capabilities to Seek Out
When assessing a prospective partner, ensure to check for these major capabilities.
- In-House Engineering & Design Teams: A partner who is able to assist in the manufacturing (DFM) will be highly beneficial.
- Complete Toolroom: Do they have no die establishment? If they do, they can control the time and quality.
- Quality Certifications: Certs like ISO 9001 should be sought. They reflect their quality goals.
- Proven Track Record: Request for some samples of parts that are made in the past by them. This shows their experience.
The Importance of a Genuine Partnership
You should seek for more than just a supplier, you need a partner. A company which communicates well and works directly with you will solve problems, and also improve your product at the same time. Additionally, a partner who is reliable like Mekalite will extend their service as if they are part of your team. Their focus is on your success.
