Stamped Parts Manufacturer – Precision for Series Production – Alfred Kron GmbH

Alfred Kron GmbH from Solingen is your B2B expert for high-precision stamped parts, stamped and bent parts, pressed parts, formed parts, busbars, and hybrid parts made of metal and plastic. For decades, we have guaranteed quality, precision and on-time series production for automotive, the electrical industry, mechanical engineering, medical technology and household goods.

Our state-of-the-art stamping machines (Bihler, Bruderer, Herm Raster, Andritz-Kaiser) in combination with our own injection molding machines from Arburg and Netstal enable the economical production of even complex components. High-precision material feeding, exact stamping and optional forming processes ensure repeatable quality with minimal material loss.

The combination of metal and plastic – that is, stamped parts overmolded with plastic – are "hybrid parts". Hybrid parts are overmolded directly in plastic via insert molding, creating insert molded assemblies that combine the highest mechanical stability, electrical insulation and functional integration. This results in durable, precise and economical components for demanding industrial applications.

Thanks to our own toolmaking and integrated design, we realize individual solutions "from a single source". Certifications to IATF 16949 and ISO 14001 guarantee the highest quality standards and sustainable production processes.

Our stamped products are successfully used in automotive (body, chassis, interior), mechanical engineering, the electrical industry (circuit boards, contact springs, busbars), household goods, the lamp and luminaire industry, building technology and medical technology.

Production at Your Stamped Parts Manufacturer: Materials and Applications

Precision stamped parts form the backbone of industrial metalworking. They combine precise mechanical function with economical series production. Alfred Kron GmbH manufactures these components tailor-made on a modern machine fleet, supported by in-house toolmaking and certified quality.

Difference Between Stamped Parts and Stamped & Bent Parts

• Stamped parts: predominantly flat and geometrically defined. Where present, they have only a few bends; their function is mostly fulfilled through holes, cut-outs or embossing.

Stamped parts for battery terminal plates

• Stamped and bent parts: additionally contain dominant bending processes, dynamic elements such as springs, and complexly bent structures
• Use: stamped parts for precise blanking; stamped and bent parts for complex shapes or spring functions

Manufacturing Process

Material feed: automatic strip and wire feeding for minimal losses.

Stamping: precise blanking of holes, cut-outs, notches and embossing.

Our stamping and stamping-bending machines:

• Bihler: small to medium components, stamping + light forming
• Bruderer: medium to large series, short cycle times
• Andritz-Kaiser: filigree contours, deep stampings
• Raster: high load, industrial large-scale series

Post-processing: deburring, forming, preloading; integrated processes reduce the machining effort.

Quality assurance: inspection of dimensional accuracy and contour, freedom from burrs and surface quality, IATF- and ISO-compliant, testing by means of digital measuring systems and regular random sample checks.

Practical Example of an Industrial Stamped Part

For an industrial customer in building technology, we regularly produce stamped parts from C75 S steel strip in 2.0 mm material thickness, which connect cable ducts in hall ceilings with a holding device. The stamped parts are stamped on a Bruderer stamping press, hardened in our in-house hardening shop and electrogalvanized against corrosion.

Thanks to the progressive compound principle and intelligent part connections in the carrier strip – produced directly from the coil – up to 25 sequential bends in all directions can be realized. This eliminates individual work steps and enables efficient production in our stamping shop. As a matter of principle, we rely on automated output with tool-integrated adjustment options for the setter, which are always accessible from the outside. One example of this is a retaining plate made of stainless steel strip (1.4301) with a material thickness of 0.4 mm, which is used in the lamp and luminaire industry.

Materials

• Unalloyed steels: robust and economical
• Spring steels: dynamic load, springs, contact springs
• Stainless steel (1.4301 / 1.4310): corrosion-resistant, hygienic applications
• Copper & copper alloys: high conductivity, electroplated coatings possible
• Aluminum: lightweight, dimensionally stable, corrosion-resistant

Areas of Application

• Automotive: spring and retaining elements, conductor contacts, IATF-tested series
• Electrical and electronics industry: circuit board contacts, relay springs, switch components, busbars
• Mechanical & plant engineering: assembly and connecting elements, guide elements
• Household goods / medical technology: functional elements, clamps, hybrid parts, insert molded assemblies

Advantages

• High precision & dimensional accuracy
• Economical series production
• Flexible choice of materials and components
• Insert molding & hybrid parts enable complex assemblies with electrical insulation and mechanical stability
