Our range of stamped metal parts
Metal stamped parts are so versatile
Stamped part
A stamped part is defined as an item that is stamped out of sheet metal without any significant deformation of the component. However, these parts, which appear “simple” at first glance, often have hidden challenges in the details.
There are often strict flatness and parallelism requirements and limited thickness tolerances for the raw material. If, for example, counterweights are manufactured from it, the weight is a critical feature that can only be achieved with very limited thickness tolerances.
We are manufacturers of such stamped parts and can produce them according to your requirements.
Stamped and bend part
As the name suggests, stamped and bent parts are parts that are stamped and then bent/formed. There are numerous applications and areas of use, ranging from “simple” to very complex geometries/formations. Here, too, the finer details are crucial in terms of the requirements placed on the item and where it is used.
Different materials “behave” differently, with the material quality and the respective strength of the material used playing a role. When using spring steel, for example, the spring effect must be calculated in advance in order to achieve the desired properties and dimensions in the finished part. These factors are already taken into account during the design of the tools.
As a supplier of stamped parts with our own toolmaking facility, we have the necessary expertise to implement these factors.
Stamping assemblies
If additional parts such as stamped nuts, press-fit screws, threaded pins, or similar components are welded or pressed onto the stamped part, this is referred to as stamped-part assemblies. The feed of the assembly parts must be perfectly coordinated with the tool and machine. At running speeds of up to 200 strokes per minute, every thousandth of a second counts to guarantee smooth production.
Here, too, our in-house toolmaking department is a decisive advantage for the implementation of projects. As a manufacturer of stamped parts and stamped assemblies, the interaction between production and toolmaking is essential for the fine-tuning of processes.

What should be considered when using different material?
Another decisive factor for the subsequent application and manufacturability of stamped parts is the choice of material.
There are stamped parts made of steel, stamped parts made of aluminum, stamped parts made of stainless steel, stamped parts made of copper, and many more. Each material has different properties, and the choice depends on the areas in which the stamped parts will later be used. Do they need to be corrosion-resistant? What strength is required? Should the material have a springy effect? Does it need to be conductive? What is the function of the finished article and what external influences will it be exposed to?
The properties of the material are also important for the design of the tool; we must consider in advance how the material will behave during the stamping and bending process.

Reasons to use stainless steel
Stainless steel stamped parts are used in the pharmaceutical and food industries, among others, due to their corrosion and acid resistance. Stainless steel is also frequently used in the furniture industry because of its surface structure and because it is hygienic and durable. Stainless steel has the advantage that no additional corrosion protection/surface protection needs to be applied.

Reasons to use spring-steel
Spring steels is resilient. This material is used, for example, for staples. Depending on their subsequent application, stamped parts made of spring steel often have to be heat-treated to increase their durability. This is necessary, for example, in cases of high loads or frequent load changes in subsequent applications in order to prevent material breakage.

Reasons to use Aluminium
Aluminum stamped parts are used, among other things, when weight savings are required. The various alloys, which differ in terms of strength and mechanical properties, are important for use and application. The most commonly used alloys are AlMg1 or AlMg3. Aluminum is lighter than steel, it is highly malleable, has high strength, and is highly corrosion-resistant. Which material is suitable for which application must be determined on a case-by-case basis.
