What TMCOMAS does

TMCOMAS (legal entity: Talleres Mecánicos Comas S.L.U.) is a privately held, family-owned Spanish industrial services company founded in 1952 and headquartered in Blanes, Girona, on a single ~6,000 m² site. The firm provides integrated mechanical and surface engineering services — primarily rotating-equipment repair (pumps, gearboxes, compressors, turbine and compressor rotors), Laser Cladding using Laserline FDK VG4L 1000-4000 diode laser systems, Thermal Spray coatings (APS, HVOF, HVOF-W, Arc Spray, Combustion), Special Welding (WPS/WPQR/WPQ-qualified), Babbit bearing manufacturing and repair, precision machining of steels and superalloys, and reverse engineering/NDT inspection — to petrochemical, energy, chemical, steel, plastics, and heavy-industrial customers.

The technology stack centers on advanced surface engineering: two complete Laserline-based laser cladding installations featuring a proprietary online melt pool control system that regulates energy application to maintain coating homogeneity and minimum-constant dilution, plus a new HVOF rig capable of coating internal diameters from 330 mm via perpendicular and 45° projection. The company holds ISO 9001:2015, nuclear certification, API standards, and Level 2 NDT credentials, and maintains a temperature- and humidity-controlled vertical rotor warehouse storing critical spares up to 10 tonnes with a 48–72 hour delivery guarantee and 12-month warranty. It allocates approximately 12% of turnover to R&D through permanent research agreements with CPT (University of Barcelona), AIN, AIDO, AIMEN, CTM-EURECAT, and IK4, and participates in subsidized consortia (FAMPAI, r3MYDAS, BIOENERGY) with CDTI and ACCIÓ.

Revenue is generated through project-based, quote-driven B2B contracts priced on unit rates for labor, equipment usage, materials, and transport. The go-to-market is direct enterprise field sales with technical and metallurgical advisory embedded in delivery. Customer concentration is anchored on large Spanish industrial enterprises (Repsol, Petronor, Cepsa, Iberdrola, Dow, Celsa, Ercros, UBE, Elix Polymers, KEM ONE, Fertial), with international references in France and North Africa. The company remains under founding-family ownership (Comas family, with Llorenç Comas Puig as CEO and Georgina Comas Vieta and Llorenç Comas Vieta as Deputy CEOs) with no disclosed parent, institutional investors, M&A activity, or plans for public listing.
