Sheet metal components
As a specialized company, Karl Naumann GmbH offers a wide range of stamped sheet metal components. We differentiate our production according to the degree of complexity, the process used and the intended function in order to deliver the most economical solution for every industrial requirement.
Differentiation by manufacturing process
- Simply punched sheet metal parts: Karl Naumann GmbH manufactures these basic components using efficient single-cut processes. These are mainly flat geometries such as washers, spacer plates or simple mounting brackets for mechanical engineering.
- Stamped and bent sheet metal parts: We create three-dimensional objects by combining cutting and forming processes. Typical examples are complex contact springs, assembly clips or precise brackets.
- Progressive composite parts: We use state-of-the-art progressive dies for production. The strip material is fed through the system step by step, with operations such as punching, embossing and bending taking place at each stroke. This is our standard process for maximum precision in series production.
- Insertion work as an intermediate or final process in production
According to geometry and functional design
- Deep-drawn components: We combine classic stamping with deep-drawing technology. This is how Karl Naumann GmbH creates hollow bodies, shells or cup housings from flat starting material.
- Composite elements: Stamped parts are joined together by welding, embossing, screwing or riveting
- Perforated elements: These are characterized by repetitive hole patterns and are manufactured by us as filter elements, ventilation grilles or decorative cladding.
- System-integrated components: Karl Naumann GmbH already integrates additional functional elements such as threads, bolts or press-in nuts in the punching tool, which drastically simplifies your subsequent assembly.
Variety of materials at Karl Naumann GmbH
Depending on the strength or conductivity requirements, we process a wide variety of sheet metal grades:
- Sheet steel: from standard cold-rolled strip (DC01) to galvanized grades and high-strength special steels for the automotive sector.
- Stainless steel variants: Corrosion-resistant sheet metal stampings from Karl Naumann GmbH, mostly made from 1.4301 (V2A) or 1.4404 (V4A).
- Non-ferrous metals: Aluminum for lightweight construction as well as copper and brass for electrically conductive contact elements.
- Spring steels: Especially for components that require a high elastic recovery.
Surface quality and edge finish
- Vibratory grinding (barrel finishing): Karl Naumann GmbH uses mechanical processes to safely remove punching burrs and smooth surfaces.
- Industrial coatings: To optimize corrosion protection or appearance, our parts are powder-coated, KTL-painted or electroplated (e.g. galvanized).
- Thermal treatment: Case-hardened or tempered components offer maximum wear resistance for highly stressed assemblies.
