Our process
From concept to fabrication-ready
A structured, code-driven workflow so every drawing that leaves MEXWORX is shop-floor accurate.
- 01
Requirement & data sheet review
Process data sheets, codes, and client specs are reviewed and scoped.
- 02
Design & simulation
Mechanical design, thermal rating, and FEA/CFD simulation validate performance.
- 03
3D modeling & drafting
Parametric 3D models generate fully detailed fabrication drawings.
- 04
QA review & handover
Independent checking, client review cycles, and final issue for fabrication.

★★★★★
“MEXWORX turned around our heat exchanger fabrication drawings in half the time our previous vendor needed — and the QA was flawless.”Daniel ReyesProject Engineer, Thermocore
★★★★★
“Their FEA and simulation work on our pressure vessel caught a stress concentration issue early — saved us weeks of rework.”Priya NathanDesign Manager, Vessel&Co
★★★★★
“Solid API 661 air cooler package, accurate 3D models, and responsive communication throughout the project.”Marcus WebbProcurement Lead, AeroCool Ind.
