AFFES

What AFFES does

AFFES (legal name Aceros Fundidos Forjados Especiales, S.L.) is a Valencia, Spain-based custom metalmechanic manufacturer founded in 1997. The firm engineers, develops, and fabricates bespoke industrial components and spare parts for heavy-industry clients, with core product lines spanning custom gears (spur, helical, conical, bevel, and chevron), speed reducers, heat exchangers, conveyor belt components, mineral processing equipment parts, crusher and mill components, furnace parts, fluid transport equipment, and industrial machinery repair services. Notable technical capabilities include the manufacture of crown gears up to 5 meters in diameter, support rings of equivalent size for iron-ore recoverers, speed reducers rated for 30,000 MW gas turbines with input speeds of 5,300 rpm, and 65-ton heat-exchanger tubular bundles with approximately 1,500 tubes each rated for 250°C and 25 atmospheres.

The company's revenue model is project-based B2B manufacturing: every order is quoted individually after engineering consultation, with no published pricing and no intermediaries. AFFES serves six heavy-industry verticals — oil and gas (including hydrocarbon cryogenic plants), electrical power generation (hydroelectric, coal-thermal, and gas-turbine), iron and steel (mining through cold rolling), aluminum (bauxite to lamination), cement, and mining (gold, copper, bauxite, iron). Multi-year contract cadences and custom-engineered specifications create client-specific drawings and qualification work that lock in repeat business.

Distribution is direct enterprise field sales; the company markets through its bilingual corporate website and handles inquiries via direct contact forms and phone. Manufacturing is performed in-house using a substantial installed base of precision equipment from manufacturers including Lambert, Koepfer, Pfauter, Klingelnberg, Reishauer, Oerlikon, Kitamura, and Deckel-Maho. The firm has 1-10 employees per available firmographic data and is privately held as a Spanish Sociedad Limitada, with no disclosed investors, parent company, or funding rounds.
