SHWire

What SHWire does

SHWire (legal entity Schwering & Hasse Elektrodraht GmbH) is a German specialty manufacturer of enamelled copper and aluminum wire (magnet wire), founded in 1858 as a cigar manufacturer in Lügde and transitioned to wire production after World War II. Now in its fifth generation of family ownership, the company operates Europe's largest single-location enamelled wire manufacturing facility in Lügde, with 300 production lines, 60,000 tons of annual production capacity, approximately 50 million kilometers of yearly output, a 90,000 m² facility footprint, and 21,000+ automated high-bay pallet positions. SHWire is part of the SynFlex Group alongside SynFlex; together the group employs almost 800 people, with approximately 250 specialists concentrated at the Lügde site.

The company's product portfolio is organized into five core lines: SH*X*Life® (800V+ high-voltage enamelled copper wire for next-generation EV drivetrains with partial discharge resistance, including 220, 220 Flat, and 240 PI Flat variants), SH*Sold®* (solderable enamelled wire enabling direct soldering without insulation stripping), SH*Therm®* (high thermal resistance enamelled wire with thermal class ratings from 180 to 240, including a 210 TE traction-motor-optimized variant and SHGlide self-lubricating coating options), SH*Bond®* (self-bonding enamelled wire for self-supporting coils), and SH*Bare®* (bare uninsulated wire in round and flat profiles). Supporting services include Syn*Lab® (UL-certified in-house testing laboratory), SynServ (technical consulting and application engineering), and metal trading services providing direct London Metal Exchange (LME) access and copper hedging. Differentiating technology includes a patented HFZ high-voltage error count test method, a proprietary FIT Production Monitoring Platform (described as AI-ready for predictive process control) supporting 100% inline inspection, in-house coating chemistry synthesis, and a Winding Wire Matrix methodology for structured translation of customer requirements into product specifications.

SHWire operates a sales-led enterprise B2B go-to-market model with technically experienced direct sales contacts providing application engineering support and account management under unified sales management covering key accounts, order center, production planning, and logistics. Pricing is quote-based, multi-year, and not publicly disclosed. Revenue is generated primarily from hardware sales of enamelled wire, supplemented by transaction-fee revenue from metal trading services and professional-services revenue from technical consulting and laboratory testing. Customer relationships are characterized by long-term continuity, evidenced by repeat awards including the Bosch Supplier Award (11 times), Siemens Star Award (3 times), Magna Innovation Award, and the 2025 Großer Preis des Mittelstandes finalist recognition. Certifications include IATF 16949, ISO 9001, ISO 14001, ISO 50001, ISO 45001, and TISAX (confirmed December 2025). Revenue is not publicly disclosed.
