Mechanical Assembly & FAT Testing
First In Service OÜ delivers complex mechanical, electrical, and hydraulic assemblies with Factory Acceptance Testing and full Manufacturing Data Record documentation from Tallinn, Estonia.
Complex assemblies and fully FAT-tested modules, delivered installation-ready with complete Manufacturing Data Records.
Complex assemblies and fully FAT-tested modules for demanding industrial applications. From precision bearing installations to fully commissioned units, we assemble, verify, and deliver with comprehensive documentation.
Complex mechanical, electrical, and hydraulic assemblies, from precision bearing installations to fully commissioned, ready-to-install units.
Factory Acceptance Testing verifies a module functions correctly before it leaves our workshop. We deliver fully FAT-tested modules with complete test protocols.
A full Manufacturing Data Record (MDR): material certificates (3.1/3.2), NDT reports, dimensional logs, and FAT protocols.
Yes. Our assembly scope covers mechanical, electrical panel wiring, and hydraulic system integration and pressure testing.
Yes, where scope requires it. We assemble, verify, and commission before delivery, so the unit arrives installation-ready.
The difference between a box of correct parts and a working system is everything that happens in assembly: bearing seats measured and matched before installation, torque sequences that load a structure evenly, hydraulic circuits flushed to cleanliness class before first pressurisation, and electrical systems point-tested against the schematic rather than assumed from it. Our assembly team plans this sequence in advance — tooling, lifting, quality hold points — so the build runs to a procedure, not to improvisation.
Factory Acceptance Testing is where scope ambiguity goes to be resolved. We agree the FAT protocol with you before assembly starts: what is tested, to what acceptance criteria, witnessed by whom. When the unit passes, you have documented proof of function before transport risk and site-installation variables enter the picture — which is precisely the point of testing at the factory.
The delivered package is a commissioned unit and its Manufacturing Data Record: material certificates, NDT reports, dimensional logs, and signed FAT protocols. Installation-ready means your site team bolts it down and connects it — not that they finish building it.
