Alfred Kron GmbH from Solingen is your experienced B2B manufacturer for high-precision EMC contact springs – elastic metal springs that reliably shield electromagnetic interference and ensure secure electrical contacts in devices. Using state-of-the-art stamping and stamping-bending technology on BIHLER machines, we produce springs that are precisely tailored to the requirements of electronics, automotive and industry.
Spring elements for EMC shielding ensure:
- Effective shielding of electromagnetic interference
- Secure connection between circuit boards and housings
- Continuous contact guidance for long-lasting operation
Production uses high-quality materials such as stainless steel 1.4301/1.4310 for corrosion resistance or copper alloys CuBe2 / CuSn6 for high conductivity. Through precise stamping, bending and forming, springs are created with consistent dimensional accuracy and high repeatability. Complementary surface treatments such as galvanizing, nickel-plating or powder coating ensure longevity and corrosion protection.

Shielding Springs for EMC – Production, Properties and Applications
Shielding in modern technology
EMC contact springs are indispensable components for ensuring electromagnetic compatibility (EMC) in electronics, automotive and industrial plants. Alfred Kron GmbH produces high-precision springs that combine shielding, conductivity and long-lasting function.
What are EMC contact springs?
Contact springs for electromagnetic shielding are resilient metal elements with shielding properties that:
- Minimize EMC interference in devices
- Reliably connect circuit boards to housings
- Enable continuous electrical contacts
Typical areas of application: electronic housings, circuit board contacts, telecommunications, automotive and industrial applications.
Practical Example
Solderable "connectors" made of 0.3 mm nickel silver CW403j for receiving and permanently fastening electronic components, as a plug & play connection, without additional soldered joint.
Weldable and solderable "ground plates" made of 0.8 mm copper strip Cu-ETP, with integrated spring contact and mounting points for automated further processing.
Clampable, snap-in, solderable and pluggable "shielding housings" for EMC applications in various sizes made of 0.4 mm CuSn6 material.
EMC-shielded contact connectors with convex spring action for improved clamping contact, made of Cu-ETP strip in 0.4 mm material thickness.

FAQ
What are EMC contact springs and how do they work?
Spring elements for EMC protection are elastic metal components used to ensure electromagnetic compatibility (EMC). They act as a physical connection between electronic components, safely conduct electrical currents and reliably absorb or divert electromagnetic interference.
Which materials are suitable for EMC contact springs?
Since conductivity and corrosion protection are decisive, we manufacture EMC shielding springs from highly conductive materials. Special copper alloys (such as CuBe2 or CuSn6) or corrosion-resistant stainless steel (e.g. 1.4301 or 1.4310), which have optimal spring properties, are frequently used. Our materials and surface treatments are of course RoHS-compliant.
For which industries and applications are the springs suitable?
EMC contact springs are used wherever sensitive electronics must be protected from interference. The focus is on the electronics and telecommunications industry, medical technology, the automotive sector (e.g. in control units) as well as demanding mechanical engineering.
How are EMC spring elements manufactured at Alfred Kron?
Production takes place through precise stamping and stamping-bending processes on state-of-the-art BIHLER machines. This allows us to form complex geometries in a single operation and ensure extremely high repeatability. Tailor-made special solutions according to individual design specifications are also easily possible.
What is the service life of EMC spring elements?
Thanks to the use of high-quality, fatigue-free materials and refining surface treatments (such as galvanizing or nickel-plating), our EMC spring elements have an extremely long service life. They guarantee low-maintenance and reliable shielding over many years.
How quickly can custom-made EMC springs be produced?
The exact production time depends on the complexity of the geometry and the specific customer requirements. Thanks to our modern machine fleet and experienced processes, however, we can usually realize very fast delivery times – from the first prototype to series production.
Conclusion
EMC shielding springs from Alfred Kron combine precise production, high-quality materials and reliable function. They ensure EMC compliance in electronics, automotive and industry – from development through prototypes to series production.
