What Pieron does

Pieron GmbH is a 100-year-old, fourth-generation family-owned German manufacturer of precision technical springs, stamped and bent metal parts, and wire-formed components, headquartered in Bocholt, Germany. The company produces more than one billion components annually, with a core product set spanning wave springs, torsion and compression springs, stamped bent parts, wire bent parts, and clamping/lamellar rings (the latter made via a proprietary low-burr cut geometry and double-layer winding process developed with material suppliers). Pieron's primary customer base is the automotive industry — its springs are reportedly present in nearly every car clutch worldwide — with secondary applications in general mechanical engineering, electrical engineering, and a growing e-mobility product line covering canted coil springs, contact terminals, busbars, wound coils/chokes, and HV connectors for EV power electronics and charging infrastructure.

Pieron operates five production locations worldwide: its headquarters and main plant in Bocholt, Germany; a joint-venture manufacturing site in Holland, Ohio (USA); a JV in Taicang, China; and a cooperation in Tumkur, India. This footprint enables a local-to-local sourcing model for the major automotive markets of Europe, North America, and Asia. The company runs the full value chain in-house from product development and prototyping through in-house toolmaking and series production, supported by IATF 16949:2016, ISO 9001:2015, and ISO 14001:2015 certifications. Revenue is generated via B2B direct enterprise sales of custom-engineered hardware to automotive OEMs, Tier 1s, and industrial manufacturers; pricing is not publicly disclosed and is handled via direct quote, consistent with engineered-component business. The company is privately held (Pieron GmbH), led by Managing Partner Sven Pieron and Managing Director Christian Fehler, with a global workforce of approximately 379 employees.

Products and services

• Technical Springs Pieron's overarching product line encompassing wave springs, stamped bent parts, canted coil springs, rings and lamellar rings, wire bent parts, torsion springs, and compression springs manufactured for industrial applications across automotive, mechanical engineering, and electronics sectors.
• Clamping Rings and Lamellar Rings Double-layer wound clamping rings manufactured from spring-hard materials with low-burr cuts, featuring special cut and leg geometry for secure hold on rubber-metal assemblies. Produced in wire diameters of 0.2-8.0 mm with outer diameters exceeding 120 mm available on request. Annual production exceeds 300 million rings supplied internationally.
• Canted Coil Springs (Ring-Kontaktfedern) Springs designed for mechanical connections and transmitting electrical currents. Each individual coil serves as a contact point, compensating for tolerances or vibrations and enabling maximum electrical current. Used in connectors on electric motors and charging stations.
• Contact Terminals Components that connect busbars, wires, cores, and electrical cables. Once installed, they ensure a permanent and secure connection. Available with custom solutions including clamping force design and anti-loss protection.
• Busbars Used to distribute power in electric vehicles. Plastic overmoulding provides electrical insulation for copper and aluminum busbars, ensuring safe distribution of high-voltage currents. Custom-shaped geometries enable high degree of automation during installation.
• Wound Coils / Chokes Edgewise wound coils or chokes made of flat and round materials that limit currents in electrical cables. Used in power supplies of electrical devices, power electronics, photovoltaic inverters, power generation, and charging systems for electric cars.
• HV Connectors (High-Voltage Shielding Sleeves) High-voltage connectors that protect conductive or surrounding components in charging plugs from electrical and magnetic fields. Suitable for transmission of large electrical energy currents.
• Wave Springs Technical wave springs used in various industrial applications requiring compact spring force solutions.
• Stamped Bent Parts Precision stamped and bent metal parts manufactured for industrial applications.
• Wire Bent Parts Custom wire bending parts manufactured for technical applications in industrial settings.
• Torsion Springs Technical torsion springs designed for industrial applications requiring rotational force storage.
• Compression Springs Technical compression springs used in various industrial applications requiring axial force storage.
• E-Mobility Solutions A product line serving as a development partner for companies optimizing components for electric vehicles, encompassing electromechanical components including canted coil springs, contact terminals, busbars, wound coils, and HV connectors.
