What Sinterleghe does
Sinterleghe S.r.l. is a privately held Italian industrial manufacturer founded in 1989 by Eugenio Tedeschi, specializing in resistance spot welding equipment for automotive body-in-white assembly. The company designs, produces, and sells three integrated product lines under the Ravitex brand: tip dressers (electrode refinishing machines), electrode changers (automated electrode replacement systems), and patented RX.2 three-blade hard metal (carbide) cutters, alongside HSS single-blade cutters and accessory tooling. Production is anchored at a single CNC 4.0-equipped facility in Anzola d'Ossola, with 100% internal machining for patented RX cutters and 80% internal mechanical processing for dressers and changers; the firm maintains annual capacity of 18,000 carbide cutters and 2,000 dressers/changers.
The business operates on a hardware-sales model plus a recurring technical-services and spare-parts stream, with pricing handled via quotation rather than published rates. Sinterleghe goes to market through direct enterprise sales combined with the Ravitex Global Network Partner program — 10 authorized distributors covering North America, Latin America, Europe, India, and China — and two wholly-owned subsidiaries, Ravitex GmbH (Germany, est. 2000) and Ravitex Ltda (Brazil, est. 1999). Customer concentration sits in automotive OEMs and Tier-1 suppliers (Tesla, Volkswagen, Audi, BMW, Ford, Stellantis, Volvo, Mahindra, BYD, NIO, SEAT, ABB, KUKA, Comau, TATA Motors), with products qualified at approximately 120 plants worldwide and protected by 9 worldwide patents plus ISO 9001:2015 certification.
The company is family-controlled, with no disclosed external institutional investment, and operates from a 35-year heritage in Italian carbide processing. Its competitive position rests on proprietary dressing technology, deep OEM-qualification relationships, and a globally distributed service network that smaller niche competitors would struggle to replicate.
