Stamped parts Manufacturers online

Stamped parts are produced by cutting and forming sheets or plates of different metals, foils, plastics, composites, paper and cardboard or leather using tools in presses or suitable punching machines.

In this process, a workpiece is stamped out of a sheet, metal plate or other suitable material using a punching tool and thus shaped into the desired form. Punched parts are used in a variety of industries as they are cost-efficient, precise and can be produced in large quantities.

Below you will find an overview of the processes, the most commonly used materials and an overview of the use of stamped parts and their advantages:

The processes for manufacturing stamped parts:

The production of stamped parts involves various highly developed processes, which are selected depending on the requirements for the part, the quantity and the material properties.

1. Cutting: (punching)
   In classic cutting or punching, workpieces are stamped out of a metal strip or sheet or other materials. This is done with the help of a stamping tool mounted in a press. The presses can be mechanically, hydraulically or pneumatically driven.
2. Fine blanking:
   Fine blanking is a high-precision stamping process typically used for applications where very smooth edges and tight tolerances are required.
3. Bending:
   In addition to stamping, bending is also commonly used as a process to create three-dimensional shapes from flat stamped parts.
4. Deep drawing:
   Deep drawing involves pressing a flat sheet or sheet of plastic into a deep drawing mold to create deep, hollow shapes.
5. Laser cutting:
   Laser cutting is a non-contact cutting process that is often used for prototypes or small series.
6. Embossing:
   Embossing is a process often used to add surface textures or patterns to stamped parts.
7. Progressive die cutting:
   Progressive die-cutting combines several work steps such as cutting, bending and embossing in one work cycle.
8. Pressure die-cutting:
   Pressure die-cutting uses high pressure to shape or separate the material, often for thicker or harder materials.
9. Nibbling (also known as nibbling) is a flexible cutting process used more for irregular or complex cuts.

The efficiency, precision and adaptability of each process play a crucial role in choosing the right production process.

Below is an overview of the most important points to consider when purchasing stamped parts:

When purchasing stamped parts, there are several important criteria that must be considered to ensure that the parts meet the requirements of the application and are delivered in the desired quality.

• The raw material is decisive for the properties of the finished stamped part.
• Purchasing should ensure that the material meets both the mechanical and normative requirements.
• Factors such as strength, ductility, corrosion resistance and conductivity play a role here.
• For special applications, such as in electrical engineering or medical technology, high-purity materials or biocompatible materials are required.
• The traceability and certification of materials is also essential in many industries.
• Stamped parts are often required in large quantities, but must still be manufactured with high precision in order to fulfill their function.
• Purchasing should ensure that tight tolerances resulting from the subsequent fit or function are adhered to.
• For safety-critical applications, e.g. in the automotive or aviation industries, tight tolerance ranges and test protocols are crucial.
• The surface quality is equally important: depending on the requirements, a burr-free finish, polished surface or special coating may be necessary.
• The choice of manufacturing process influences costs, precision and flexibility.
• Classic punching is suitable for simple geometries, while fineblanking is necessary for particularly clean cut surfaces.
• For complex series, the progressive die, which combines several work steps in a single pass, is ideal.
• The supplier's options in terms of forming techniques such as bending, embossing or deep drawing should also be taken into account.
• Modern additions such as laser cutting or water jet cutting can be decisive for prototypes and small series
• A significant cost factor in stamping is the manufacture and maintenance of the tools.
• When purchasing, it is important to clarify who bears the costs for tools, whether they are included in the price or shown separately, and how long the tools can be used.
• Durable, wear-resistant tools are a decisive factor for cost-effectiveness, especially for large series.
• The selection of a qualified supplier is crucial.
• Certifications such as ISO 9001, IATF 16949 for the automotive sector or ISO 13485 for medical technology provide assurance that the manufacturer works according to recognized standards.
• Experience in the respective industry, references and the ability to support product development are also important criteria.
• Some manufacturers offer co-engineering, where they are involved in the development process at an early stage, thus enabling optimal manufacturing solutions.
• When purchasing, attention should be paid to a comprehensive quality assurance system at the supplier. This includes tests such as dimensional accuracy tests, hardness tests, crack tests and surface inspections.
• Modern suppliers rely on digital test reports and batch traceability. For safety-critical applications, a 100% inspection or SPC (Statistical Process Control) is often necessary.
• Many stamped parts are further processed after the actual manufacturing process. This includes surface coatings such as galvanizing, nickel-plating or anodizing, heat treatments or cleaning processes.
• Purchasing should clarify whether the supplier offers these services itself or works with partner companies.
• A "one-stop shop" solution reduces interfaces and potential sources of error.
• Costs are a key purchasing criterion - not only per part, but also the overall process costs. Small batch sizes are more expensive, while large series quickly amortize the tool costs. Purchasing should check whether the supplier can react flexibly to fluctuating requirements, for example with buffer storage or just-in-time deliveries.
• Reliable delivery times are crucial for global supply chains. Purchasing should pay attention to short response times, transparent delivery processes and, if necessary, regional alternatives in order to reduce risks in the supply chain.
• Packaging solutions that protect the stamped parts from damage during transportation and storage are also important.
• The issue of sustainability is becoming increasingly important. Buyers should check whether the supplier uses environmentally friendly processes, recycled materials or is ISO 14001 certified. Compliance with international standards such as REACH or RoHS is also particularly relevant for stamped parts for electronics and automobiles.

When purchasing stamped parts, it is not just about the lowest price, but also about the right combination of material quality, precision, tool and manufacturing expertise, supplier quality and long-term security of supply. Taking these factors into account ensures that stamped parts fulfill their function reliably, economically and sustainably.
