The process of metal stamping is a complex procedure that results in the bending or blanking of the metal. It is a technique of modifying the metal sheets into different shapes. It can be used for things like retro campers and RVs as well.
Usually, this method is performed with the use of presses in a cold environment where the tools will modify the shape of the sheet. The efficiency of this process is high since it can be relatively cheap. It is also conducted at high speed. Therefore, multiple identical components can be produced, yielding a high volume.
You’ll learn everything about what metal stamping is.
Various processes will use specific physical operations to form the desired parts. Some of them include:
- Punching: This process aims to create holes in the metal sheet using a punch press to force the tool through the sheet. Usually a cold-forming process, this method is one of the most cost-effective processes available.
- Embossing: This is the process of creating a depressed or raised design in the sheet metal by pressing a raw blank against a die holding the required shape. A cold-forming technique, embossing is used to create specific shapes or designs.
- Coining: Using high pressure, coining is another common process. The sheets are formed into a precise shape by the die, creating permanent forms in the workpiece. When hit, the edges will come out smooth because they experience a high force level. Another effective method, coining, can save both time and money since any secondary procedures are no longer necessary.
- Blanking: Blanking is responsible for improving the efficiency of other stamping and finishing procedures, making it a method with significant importance for the entire process. It consists of cutting a metal form from a sheet with a rough shape that fits the final design during the blanking process. The probability of burrs emerging later is relatively low after taking this step.
- Bending: Bending is the process of forming metal into desired shapes, typically on a single axis. Metal sheets are transformed by bending procedures with multiple mechanisms being involved in bending. In some techniques, one edge of the workpiece is fixed while the opposite edge is held by a metal tool and bent over a die to achieve a precise form.
- Flanging: This technique is represented by bending the metal tabs and sections at a 90-degree angle. As opposed to typical bending techniques, this only applies to small sections of a larger workpiece. Flanging is often included in dies used in other stamping procedures to save time and money.
Progressive die: A series of stations are used for the process of progressive die stamping.
In the beginning, a coil is put into a press which is equipped with multiple progressive stamping dies. In the next step, the die will move the press as the press lowers. The die closes, stamping the metal and therefore forming the desired item.
Then, the metal advances horizontally to the next station as the press moves up. At this point, precision is important, and these movements must be exact. It’s because the component is still attached to the metal strip. Once the component arrives at the final station, it is separated from the rest of the metal. The durability of the dies is significant, making progressive die stamping a technique that can be repeatable and perfect for the long run.
Deep drawn: Used on a range of materials such as nickel, steel, copper, or brass, deep drawing is a metalworking method used in the process of metal stamping. It transforms the flat strip of metal into a part with a deep recession by repeating the same technique.
This technique is typically a punching action on the same piece. Sometimes, each operation recesses the part farther back until it reaches the desired depth.
Transfer die: Transfer die stamping uses a mechanical transport mechanism to remove the workpiece off the strip and move it between the stations, as opposed to progressive die stamping. This method is useful for designs in which the metal strip could interfere with complicated design elements. This method can also be used for the parts that are too large for progressive die stamping. In most situations, transfer die stamping eliminates the need for secondary finishing.
Multi-slide: Metal stamping with several slides are intended for items with multiple bends or complex parts. Stamping with four or more slides simultaneously shapes numerous sections of the work item.
Jewelry & Metal kits
Choosing a kit for jewelry might be a complicated task for those that are not familiar with the capabilities of such a product. Below, we will show two examples of the best kits you will find on the market today.
This jewelry kit was created to provide you with all the necessary supplies. The package includes
- an ergonomic angle brass hammer
- 3″ diameter steel round bench block with rubber base
- 72 pieces of small letters for jewelry making
- 3 enamel markers in gold, silver, and black
- 6 jewelry blanks
These jewelry tools were designed in collaboration with artisans to help you obtain the cleanest results possible. To eliminate repeated imprints and bounces while stamping, they included a 1.2lb Brass Head Mallet and individually labeled premium stamps for deep imprints on soft metals, leather, and wood. A well-crafted plated bench block with a rubber base is also included, which you can use for working on a strong and sturdy stamping surface.
When you first start out, jewelry art might be difficult. It is why they included this kit’s comprehensive e-book for jewelry making. It covers all basics, tips, and tricks from experts to help you perfect your bracelet and necklace-making skills. This e-book includes many gift and craft ideas suitable for all skill levels, from beginner to experienced.
This kit is suitable for beginners, and it includes:
- a jig
- a hammer
- a steel pedestal
- a punch set with 74 pieces that include letters, numbers, and symbols
The holder is easy to grip and is an ideal starting tool for beginners. It does a good job of protecting your fingers, and its purpose is to keep the stamp flat with the imprinted blank and metal surface until a clear and uniform impression is obtained.
It makes the process of jewelry manufacturing more comfortable and ensures that every hit will be more accurate.
The process can be difficult for beginners who lack experience, but their skills will significantly increase by practicing techniques more often.
At first, most people don’t aim for perfection. Instead, they want their results to look good. It is helpful if you are starting and will eliminate some of the pressure.
Either way, here are some tips that you can use:
Use a pencil to draw guidelines
Marking the pendants with a pencil is an easy thing to do, and it’s also helpful for further development. The markings will help properly space out the letters before stamping. In the end, you should wipe away the marks.
Stick your pendant to a stamping block by using tape
Tape your pendant down and use a stamping block for the base. Taping isn’t necessary, but it does take the concern out of your pendant flying across the table when you strike it with a hammer.
Before stamping, lay out your pieces in order.
It is not ideal for wasting 2 or 3 pendants due to misspellings, as they can be costly. You should arrange your stamps in the order they will be used before you start working on them. It will make it simpler to concentrate and keep the same amount of pressure for each hit, but it will also prevent misspellings and errors.
Hold the stamp upright.
At this step, you should hold the metal stamp firmly at its base. But be careful. Holding it too hard might hurt your fingers. Keep the stamp upright and perpendicular to the table.
Apply the perfect hit
A single stroke will be enough to imprint your desired shape on the metal. However, don’t be discouraged if you didn’t get it right the first time. Take this advice into consideration and learn from your mistakes instead.
If you hit too hard, the pendant can crack. It is always better to apply a lighter strike than you think is necessary.
Do not strike too close to the edge of the pendant. Otherwise, it will distort its shape.
Try not to repeat your hit if you missed the first time. The stamp can slide across the pendant, and you’ll have a distorted result.
Start with an easy project.
Some of the results obtained from metal stamping can be truly amazing, and you might be fascinated enough to do the same and try to reach them. Before gaining more experience, starting with easy projects such as engraving your name on the pendant is recommended.
The process requires practice, and with it, you will improve. Do not let them bring you down when you fail to get your desired results. Instead, consider it an experience that you can learn from. Also, you can use the broken pendant’s front and back for more practice.
Before starting the process, you can begin by preparing your workplace. Choose a place with a hard surface or one that can resist pounding. You could also place a piece of hardwood over your table or desk to ensure you don’t damage it. If your workplace has been set, follow the steps below:
How to stamp metal
- Place the blank on a stamping block.
Make sure to secure the blank using tape, as we mentioned earlier. It will prevent unnecessary movement while working.
- You should use a guide to space the symbols and letters evenly.
For spacing, write the desired imprint on the guide and use their marks as guidance.
- Hold the stamp at a 90-degree angle on the blank.
- Drag the stamp lightly towards the appropriate mark on the guide until it catches the edge.
Extra care and increased attention are required for this step, as the stamping blank can be easily scratched when dragging the stamp.
- Apply a little pressure and anchor the side of your palm on your workplace to keep the stamp in place.
Use the hammer to strike the material once with medium power. Repeat until the desired result is completed. In the end, remove the stamp guide and the tape.
Here are some well-known manufacturers. They are the best in this field, being the top providers of this type of work.
Clow Stamping Company – one of the industry leaders in metal component production and stamping, this manufacturer is considered a top provider. One of the reasons for their success is their intense focus on customer service and quality control.

You can find these kits available for purchase on Amazon. We recommend the IODIDO kit and the one produced by AYQWE.
There is a slight difference between the hammer heads used for metal stamping. Below, this difference is explained:
Brass heads work well because brass is softer than steel, therefore protecting the stamps from unnecessary damage.
Steel heads come in multiple forms and are excellent for directly shaping and texturing the metal sheet.
Texturing hammers also have steel heads, making them ideal for directly creating textures. They are also efficient for stamping blanks and sheet metal containing softer metals.
Nylon heads allow smoothing and straightening of a twisted metal since it has a soft head.
