An Engineering Translation Company Built for Technical Accuracy
Our network includes more than 800 professional linguists covering over 50 languages. For engineering projects, we select translators and revisers according to the subject matter, language pair, document type, and target market. This allows us to support mechanical, electrical, civil, aerospace, automotive, energy, manufacturing, medical device, electronics, and other technical sectors with the appropriate linguistic expertise.
Terminology is managed throughout the project using client references, glossaries, translation memories, and approved technical vocabulary. Where a document contains standards, units, abbreviations, or market-specific technical conventions, these elements are identified during preparation and handled consistently in the target language. Technical standards and engineering specifications are translated with the same controlled terminology process.
Engiwords supports both one-time assignments and ongoing documentation programs. Translation memories and terminology databases are maintained from project to project, helping keep future manuals, revisions, product updates, and multilingual releases consistent with previously approved content.
Whether you need a one-time technical manual translation or a long-term partner for your entire documentation library, our team scales with your projects while your translation memory and terminology stay in one place , so document number 200 sounds exactly like document number 1.
Technical documentation must remain accurate after translation. Instructions, measurements, component names, warnings, tolerances, and references all need to convey the same information as the source document. Engiwords has specialized in professional translation for more than 10 years and applies that experience to complex engineering content.
Engineering Document Translation Services for Every Format

Translation Technology That Protects Your Terminology, and Your IP
Translation memories allow previously approved segments to be identified and reused where appropriate. Termbases record preferred component names, technical expressions, abbreviations, and client-specific vocabulary. This is particularly important for documentation programs involving several files, several languages, or recurring product updates.
Client documentation is handled under confidentiality requirements appropriate to the project. NDAs can be signed before files are reviewed, and access to project material is limited to the linguists and project staff assigned to the work. Security or retention requirements can be discussed during quotation.
On the security side: encrypted file transfer, role-based access limited to your assigned team, NDAs covering every linguist, and deletion of working files on request after delivery. Your unreleased product documentation is exactly as confidential as your legal team needs it to be.
Translation technology supports consistency, but it does not replace subject-matter expertise. Engiwords uses professional computer-assisted translation tools to manage translation memories, terminology databases, repeated content, file tags, and automated quality checks. These resources are maintained at client and project level.

Case Study – Energy Industry
400 Pages of Turbine O&M Manuals, English to Canadian French
A North American energy client required the translation of a 400-page turbine operation and maintenance manual. The project included technical terminology preparation, translation by energy-sector linguists, independent revision, and layout verification before delivery.
The project glossary was retained as a client terminology resource for subsequent documentation, allowing future updates to follow the same approved vocabulary and reducing terminology review on later assignments.
“Engiwords understood the terminology requirements from the beginning and managed the documentation as a technical project, not as a generic translation assignment. The questions raised during review were relevant and well documented.”
“We needed a multilingual tender package delivered to a fixed submission deadline. The project was coordinated clearly, the terminology remained consistent across files, and the final formatting was ready for our internal approval.”

FAQs
How much do engineering translation services cost?
Engineering translation pricing depends on the language pair, source word count, technical complexity, required review level, file format, certification, and deadline. Many projects fall within a broad range of approximately $0.10 to $0.25 per source word, while CAD drawings, scanned documents, and layout-intensive files may be quoted separately. See our pricing information or send the files for an itemized quotation.
What makes engineering translation different from general translation?
Engineering translation requires more than fluent writing. The translator must understand technical terminology, document structure, measurements, abbreviations, component names, instructions, and the context in which the content will be used. Engineering documents may also refer to standards, tests, tolerances, or safety information that must remain precise in the target language.
How do you garantee technical accuracy?
Accuracy is managed through translator selection, terminology preparation, translation-memory resources, independent revision where included in the workflow, and final project-management QA. We also use client glossaries and reference material when available. For recurring work, approved terminology is retained and reused across future projects.
Can you translate CAD drawings and DWG/DXF files?
Yes. We can translate text associated with CAD drawings and DWG/DXF workflows, including annotations, notes, legends, and title blocks. The exact process depends on the file structure and software compatibility, so we review the source files before confirming the production method. Learn more about CAD drawing translation.
Do you provide certified translations for engineering documents?
Yes. We can provide engineering translations accompanied by a signed certificate of accuracy when required. Notarization and other formalities can be discussed during quotation. Because acceptance requirements vary by receiving organization, we recommend confirming the exact certification format before production begins. Learn more about certified engineering translation.
What's your typical turnaround time?
Turnaround depends on volume, language pair, technical complexity, file format, and review requirements. A single specialized translator generally handles a few thousand words per working day. Larger or urgent projects can be distributed across a coordinated team using shared terminology and translation-memory resources. Your quotation includes a proposed delivery date before the project starts.
Do you use machine translation or AI?
Our standard engineering translation service can be performed entirely by professional human linguists. Machine translation and post-editing are available only when appropriate to the project and agreed with the client. We define the workflow in the quotation so you know whether the project uses human translation, post-editing, or another approved process.
Which file formats do you support?
We handle common office and publishing formats including Word, Excel, PowerPoint, PDF, InDesign, structured localization files, and many technical file types. CAD and other specialized formats are reviewed before quotation so we can confirm the production workflow. Desktop publishing is available when translated documents must retain the source layout.
How do you handle confidentiality and IP protection?
Client files and project information are treated as confidential. We can sign an NDA before reviewing documents, restrict project access to assigned team members, and follow agreed file-transfer or retention requirements. If your organization has a supplier security questionnaire or specific confidentiality procedure, it can be reviewed during onboarding.
Which industries do you serve?
We serve more than 20 engineering and industrial disciplines, including mechanical, electrical, civil and construction, aerospace, automotive, energy, oil and gas, manufacturing, medical devices, semiconductors, electronics, and related technical fields. Translator assignment is based on the subject matter as well as the language pair.
Can you handle very large or ongoing documentation projects?
Yes. Large manuals, multi-file documentation sets, and ongoing translation programs can be managed through dedicated project teams, shared translation memories, client-specific terminology, staged deliveries, and consolidated QA. This structure is designed for companies that produce recurring technical content across products, sites, or languages.
Should I hire a freelance translator or an engineering translation agency?
A specialized freelance translator can be suitable for a single language pair and a consistent type of document. An engineering translation company is better equipped when a project involves several languages, multiple file types, independent revision, desktop publishing, urgent deadlines, or ongoing documentation. Engiwords provides centralized project management and access to a network of more than 800 linguists.
Do you translate into English as well as from English?
Yes. We translate from American English into more than 50 languages and also translate foreign-language engineering documentation into clear American English. The translator is selected according to the source language, target language, technical field, and intended audience.
