Documentation where every term carries load
In a service manual or a safety data sheet, vocabulary is not style — it is function. Render one torque value, one chemical name or one warning loosely and the consequences run from a voided certification to a hurt operator. EKO 4 National Translation Service therefore routes technical material only to linguists with formal education and working experience in the relevant discipline — engineering, chemistry, IT, energy — never to generalists.
Manufacturers and engineering firms across the country have run their documentation through us since 1991: term bases lock key vocabulary across thousands of pages, our in-house DTP team rebuilds drawings and typeset layouts, and when a tender or authority requires it, a certified translation ships in the same order — in 72 languages, to all 50 states, with express 24-hour service available.

Why engineering teams nationwide pick EKO 4
Specialists, not generalists
Every file is matched to a translator with formal training in that exact discipline, working into their native language — someone who has read a thousand documents like yours.
A term base on every project
Key terms are fixed at first use and enforced by tooling and human editors across the entire documentation set — and across next year’s revision, so updates never drift.
In-house DTP
Diagrams, tables, callouts and typeset pages are rebuilt by our own desktop publishing team, so the translated manual drops into production looking exactly like the source.
Need it official? One order covers the whole chain
Certified translation, notarization and apostille — handled in-house, in a single online order, wherever in the country you are.
Certified translation
Word-for-word translation with a signed accuracy affidavit, official letterhead and wet stamp — accepted by USCIS, courts and authorities nationwide.
Notarization
A licensed notary notarizes your translation 100% online — no office visit, ready as fast as the next business day.
Apostille
We obtain the apostille from the correct competent authority — the issuing state’s Secretary of State, or the U.S. Department of State for federal documents — end to end.

Technical translation — questions & answers

EKO 4 National Translation Service delivers professional, human translation
in up to 72 languages — coast to coast
Every certified translation at EKO 4 is produced by a vetted human linguist — educated, widely experienced and genuinely at home in both of their languages. That is what allows us to stand behind a 100% accuracy guarantee across more than three decades of work.
From our first project in 1991 to the 50,000+ clients we serve today, the formula has never changed: careful translators, disciplined proofreading and honest service. It is why a first order so often becomes a working relationship that lasts for years.
EUROPEAN
ASIAN, AFRICAN, MIDDLE EASTERN
No translation leaves our hands on a single pass. Before any linguist joins EKO 4 they are recruited, vetted, interviewed and examined; once on a project, their work moves through editors and project managers who proofread it again before it ever reaches you. That layered process is the machinery behind our 100% accuracy guarantee.
Most of our 500+ translators and editors have spent years inside international, multi-cultural projects, so the finished document does not merely say the right words — it speaks to the audience, authority or market it was written for.
Professionalism, precision and fair pricing, backed by a 100% quality guarantee. Wherever in the country you are, EKO 4 speaks your language — and your industry’s; explore every field on our terminologies page.
