What Fireplace does

Feuerherdt GmbH is a Berlin-based, privately held German manufacturer specializing in electromagnetic compatibility (EMC) shielding components, founded in 1989 by Jochim Feuerherdt. The company produces contact springs made from copper-beryllium and stainless steel with optional surface finishes (tin, nickel, zinc, gold, or silver), alongside a broader portfolio that includes conductive silicones, knitted wire mesh gaskets, conductive elastomers, dispensed gaskets, shielded windows, conductive foils, and board-level shielding enclosures. The company self-describes as Germany's most renowned EMC contact spring manufacturer, offering over 400 standard product variants plus custom-engineered solutions ranging from individual prototypes to million-unit production runs.

The business operates a sales-led, direct distribution model out of its Berlin headquarters (relocated to a newly constructed facility in 2023), with quotes generated via email, phone, and website contact forms, and short delivery times supported by a comprehensive warehouse stock. End markets are diversified across seven verticals — medical, energy, electronics, automotive, aerospace, research (including CERN, where Feuerherdt supplies EMC contact springs for the particle accelerator), and machinery/plant engineering. The company is ISO 9001 (2022) and ISO 14001 (2024) certified and markets itself on Made-in-Germany craftsmanship and engineering flexibility from early product development through high-volume production.

Following the death of founder Jochim Feuerherdt in 2023, Alexander Singer was appointed Managing Director. The company remains a single-entity GmbH with no disclosed external investors, subsidiaries, or M&A activity, and operates with a 51-100 employee headcount. Revenue, pricing, and detailed financial figures are not publicly disclosed.
