UMI

UMI (Útiles y Máquinas Industriales, S.A.) is a Spanish manufacturer, distributor, and accredited calibration laboratory with continuous operations dating to 1939 in Bilbao. Over more than eighty years the company has grown from a local industrial-tools supplier into a comprehensive metrology and testing partner for Spanish and international industry, offering services and instrumentation spanning materials testing, non-destructive testing, calibration, temperature measurement, coatings inspection, sand testing, and metallographic analysis. Headquartered at Polígono Ugaldeguren I in Zamudio, Bizkaia — within the Basque Country's dense industrial corridor — UMI also operates delegations in Torrejón de Ardoz (Madrid) and Sant Cugat del Vallès (Barcelona), enabling nationwide on-site service coverage.

Materials testing forms the technical cornerstone of UMI's business. The company designs and manufactures Universal Testing Machines (Máquinas Universales de Ensayo) for tensile, compression, bending, torsion, and fatigue tests on metallic and non-metallic specimens. Complementing its own manufactured machines, UMI distributes an extensive catalogue of hardness-testing instruments (durómetros) from leading global manufacturers, covering every principal scale: Brinell (HBS/HBW for castings and large structural parts), Rockwell in all standard and superficial variants (HRA, HRB, HRC, HRD, HR15N, HR30N, HR45N, HR15T, HR30T, HR45T for steels, carbides, and thin-section components), Vickers (HV for universal precision measurement), Knoop (HK for micro-hardness of brittle or very thin coatings), Shore, and Leeb (portable rebound method for large fixed parts). Hardness conversions between scales follow ASTM E140-12be1 and ISO 18265 with material-specific tables covering non-austenitic steels, austenitic stainless steels, brass, aluminium, copper, nickel alloys, and white cast iron — spanning the full range of industrial metallic materials.

Non-Destructive Testing (NDT / Ensayos No Destructivos) is a dedicated service and product line within UMI's portfolio. Methods available include ultrasonic testing, magnetic particle inspection, liquid penetrant testing, eddy-current testing, visual inspection, and radiographic testing. These techniques are applicable to welds, castings, forgings, and machined components in safety-critical applications such as pressure vessels, piping, structural steel, aerospace structures, and automotive parts, where detection of subsurface or surface discontinuities before service entry is mandatory. UMI supplies NDT instruments from recognised market brands and provides technical support for method selection, procedure qualification, and field application.

A key credential distinguishing UMI is its ENAC-accredited calibration laboratory, operating under accreditation number 44/LC10.024 awarded by ENAC (Entidad Nacional de Acreditación) in accordance with the international standard UNE-EN ISO/IEC 17025. The accreditation scope covers four metrological disciplines: Hardness (Dureza), Force and Torque (Fuerza y Par), Pressure and Vacuum (Presión y Vacío), and Temperature and Humidity (Temperatura y Humedad). Calibration is carried out both at UMI's own laboratory facilities and on-site at client premises (calibración in situ) — a service particularly valuable for large fixed installations or high-volume production environments where removing instruments for off-site calibration would cause operational disruption. Full metrological traceability to national measurement standards is maintained throughout, providing clients with the documented calibration certificates required under ISO 9001, IATF 16949, and aerospace AS9100 quality management standards.

Temperature measurement is an area in which UMI acts as a manufacturer, not merely a distributor. The company designs and produces industrial temperature probes and sensors (sondas de temperatura) for thermal-treatment processes including heat treatment of metals and other high-temperature manufacturing operations. Products are engineered for specific temperature ranges and operating environments encountered in metallurgy, petrochemistry, and general process industry contexts. These manufactured probes fall within UMI's own ENAC-accredited temperature calibration scope, giving clients a single-source path from probe procurement through initial verification and periodic re-calibration — a meaningful advantage for traceability-conscious quality programmes.

UMI's offering extends into several complementary quality-control specialisms. In coatings inspection (Inspección de Revestimientos), UMI is an authorised distributor of DeFelsko PosiTector instruments, including the PosiTector 6000 for coating-thickness measurement on all metallic substrates and the PosiTector 200 for non-metallic substrates, plus accessory gauges for surface profile, dew point, and environmental conditions during coating application. For the foundry and casting industry, UMI supplies a complete line of sand-testing equipment (Ensayos de Arenas) evaluating the physical properties of moulding and core sands — permeability, compressive strength, moisture, and grain fineness — as the official Spanish distributor of Multiserw-Morek (Poland), a specialist foundry-instrumentation brand. Metallographic analysis (Metalografía) encompasses specimen preparation, polishing, etching, and microscopic examination of microstructure, grain size, phase distribution, and surface-treatment depth. Additional product lines include industrial part-marking tools (Útiles de Marcaje) and predictive-maintenance instrumentation for vibration analysis and equipment condition monitoring.

The industrial sectors served by UMI encompass the broad spectrum of Spanish and European manufacturing: automotive and tier-one automotive supply chains, steel mills and metal-working plants, ferrous and non-ferrous foundries, aerospace and defence, shipbuilding, oil and gas, chemical and petrochemical processing, and general mechanical engineering. This diversified base, combined with UMI's in-house engineering and after-sales technical service team (SAT) capable of custom developments for equipment both manufactured by UMI and sourced from third parties, reinforces the company's standing as a technically credible, long-established partner for industrial quality assurance across Spain and beyond.
