Technical Translation Services
Professional translation of user manuals, engineering specifications, datasheets, and safety documentation by linguists with engineering and technical backgrounds.
When a factory worker in Vietnam reads your equipment manual, or a maintenance engineer in Saudi Arabia consults your troubleshooting guide, the accuracy of the translation can determine whether a machine operates safely — or causes injury. Technical translation is not about converting words; it is about preserving precise engineering meaning across languages, cultures, and measurement systems while maintaining the clarity that end users depend on.
At iTrex, our technical translation teams combine engineering expertise with linguistic precision. With 20+ years of experience and a network of 5,000+ specialist linguists covering 120+ languages, we have translated millions of pages of technical documentation for manufacturers, OEMs, energy companies, automotive firms, IT corporations, and construction enterprises. From 500-page service manuals and IEC-standard safety documentation to quick-reference cards and UI strings, we handle every format and complexity level.
Our ISO 9001-certified workflow includes translation by a domain-specialist engineer-linguist, technical review by a second expert, and DTP formatting that preserves every diagram, table, and callout from the source. Combined with CAT tools and client-specific terminology databases that grow with every project, iTrex delivers consistent, accurate technical translations that reduce your time-to-market and protect your brand reputation worldwide.
Key Features
Engineer-Linguist Specialists
Your technical documents are translated by professionals who hold engineering degrees and understand industry-specific terminology. From mechanical and electrical engineering to IT and aerospace, our translators speak your technical language fluently.
DTP & Diagram Localization
Technical documents are more than text — they include schematics, CAD drawings, flow charts, and annotated images. Our DTP team localizes all visual elements, ensuring that diagrams, callouts, and measurement units match the target market's conventions.
Translation Memory & Consistency
Technical documentation often spans thousands of pages with repeating terminology. Our CAT tools and translation memory databases ensure that every term — from torque specifications to error codes — is translated consistently across all documents, saving you time and reducing costs on updates.

What Our Clients Say
We localized our SaaS platform into 12 languages with iTrex, including UI strings, help documentation, and API error messages. They worked natively with our .json and .xliff files, which meant no reformatting on our end and a smooth integration with our CI/CD pipeline.
iTrex translated 1,200 pages of technical manuals for our robotic welding systems from Japanese into English, German, and Korean. The translators understood engineering diagrams, safety standards references, and maintained consistent terminology across all three target languages.
As a Swiss manufacturer exporting to DACH and EU markets, we need German translations that respect the differences between Swiss German, Austrian German, and Bundesdeutsch conventions. iTrex is one of the few agencies that consistently gets this right, especially in regulatory and compliance documentation.
