Step 3: Surface Treatment

Metal stamping parts are widely used in different industries, the parts are versatility and durability. however, in addition to these functions, the appearance is crucial for environment applications.

Surface treatment is the final step in the metal stamping process. There are many kinds of surface treatment, plated tin, plated nickel, and coatings, it improve parts’ appearance, protect against corrosion, or enhance specific properties.

it is suitable for produce high accuracy parts, such as medical devices, automotive components, and home appliances. additionally, we have many types materials, like stainless steel, aluminum, and copper alloys, the materials suitable for a wide range of applications.

advantage of custom metal stamping parts is versatility. use this stamping manufacturing method, virtually any shape or size can be achieved, the parts are suitable for a wide range of applications. Additionally, since each part is stamped individually, it allows for great precision and accuracy in producing intricate designs.

Well, we have listed some of the most popular industries that use metal stamping parts in the following table.

Metal Stamping Techniques

As mentioned earlier, metal stamping parts can be made from one or more processes. For example, a stamping part may include both making holes and bending. So, the stamping method is not just limited to one process. It has a variety of processes. All these precision metal stamping methods depend on specific project requirements.

Call To Action

Precision Metal Stamping Techniques: Punching

It is one of the most popular metal stamping techniques used in manufacturing. Stamping parts like housings or covers have many holes on the surfaces. Well, we can make these surfaces by implementing punching metal stamping techniques. Punching usually creates holes, shapes, or features in a workpiece. Overall, the process can be achieved using a punch and die set within a stamping press.

Precision Metal Stamping Techniques: Blanking

This is another type of metal stamping technique. During this process, the stamping machine only cuts useful sections. You know, it mainly depends on different applications. Therefore, this process is famous as the finished blank or simply blank. Well, you can further implement additional processes on the sheet metal based on your production needs.

Precision Metal Stamping Techniques: Drawing/Forming

This metal stamping technique doesn’t remove material from the workpiece. It’s a formative process. So, drawing or forming involves shaping a metal sheet or coil into three-dimensional components. Well, the drawing/forming process is prevalent in making deep-drawn parts like cups, cans, and other complex shapes.

Precision Metal Stamping Techniques: Piercing

Simply, we can find piercing as the opposite of the blanking method. A special punch tool makes necessary holes in the workpiece in this method. You may wonder about the differences between punching and piercing. Well, punching is the process of forming holes or features in metal. On the other hand, piercing is the process of making holes without any additional shaping.
Precision Metal Stamping Techniques: Embossing

This metal stamping method usually creates a recessed or raised section on a metal sheet. FYI: This method is absolutely not a cutting or removing process. It just raises a portion of the metal surface. For example, you can imagine a diamond plate sheet metal. You can see a lot of small raised sections on these metal plates.

Precision Metal Stamping Techniques: Coining

Coining is a very unique precision metal stamping process. The goal is simple. It just bends the sheet metal. But the way it bends is called the coining method. In this metal stamping technique, the angle of the punch or die must be similar to the angle of the required metal part. This method is actually suitable for applications where high precision is necessary. FYI: this method’s accuracy is more than the bending method.

Precision Metal Stamping Techniques: Bending

In this metal stamping method, the bend angle is not determined by the dies. Well, it depends on how far down vertically the punch presses into the die. Popular examples include brackets, chassis components, metal boxes, angles & channels, and many more.

Precision Metal Stamping Techniques: Flanging

The stamping process that makes the flanges or flares on the sheet metal is called the flanging technique. The method actually uses specialized dies or machinery to make such fabricated metal parts. However, you can create tension flanges or compression flanges based on your requirements.

Which Metal Stamping Process Is Suitable For Your Project?

We looked into several precision metal stamping processes. We also studied what metal stamping parts these methods produce. However, depending on your project application, you can evaluate which approach is best. For example, you may be confused about whether to use the coining method or the bending method. In this case, you can consider the required precision. If your project needs higher accuracy, you should use the coining method. If your project requires a cost-effective approach, you can use the bending method.
To make it easier, we have created a summary table. So our readers can easily understand the differences between these stamping methods. In addition, they can determine the best option for their project.

Precision Metal StampingFundamental Differences (Comparision With Other Methods)
PunchingThe method creates holes or other figures without shaping the material
BlankingCuts a flat metal sheet into a specified shape (focuses on cutting out a shape)
Drawing/FormingMakes metal into three-dimensional components, like cups or cylinders
PiercingIt is similar to punching. But it only creates holes rather than making shapes
EmbossingCreates raised or recessed designs on a metal surface
CoiningBending the metal parts (bend angle = the angle of the punch & dies). It offers the highest precision
BendingThe process involves bending the metal parts. Here, the bend angle is determined by how far down vertically the punch presses into the die. However, this process is less accurate than coining but cost-effective
FlangingInvolves forming edges, providing strength, sealing properties with angles or curved feature
How Do You Choose The Right Metals For The Intended Metal Stamping Process?

Choosing the right material for the intended metal stamping parts manufacturing is paramount. You know, the wrong decision influences a lot. In addition, inappropriate metal impacts the quality & functionality of the final product. Besides, you may observe other functional errors in the system as well. So, it is necessary to choose a suitable metal for the final product.
Popular metals include alloy steel, aluminum, brass, titanium, and stainless steel. For your information, alloy steel is appropriate for strength & formability. On the other hand, stainless steel is prevalent for corrosion resistance & strength. Consequently, aluminum is lightweight & corrosion-resistant.
When choosing the material, you can consider a few parameters. Well, you can evaluate their properties, formability, thickness, corrosion resistance, and cost. You know, these key considerations can help you determine the most appropriate solution. And it’s actually necessary for the reliability of your final product.

Choosing A Suitable CNC Machine For Metal Stamping Parts

Selecting the right stamping device is also important. Why? Because it determines part quality. How do you choose a CNC metal stamping machine? It’s actually simple. Just examine its specifications & features. Consider precision, power, and stamp material compatibility. Additionally, device capabilities must be considered. Here, you may check axes, spindle speed, and tool changing capacity.
Moreover, factors like control system & software compatibility also determine the machine quality. So, choosing the appropriate metal stamping parts manufacturing machine can ensure efficient production. You can also get high-quality parts & cost-effectiveness in the manufacturing operations.
