Assembly Partner for Medical Equipment Manufacturers in Mexico
Shelmex builds electronic sub-assemblies, wiring, and complete units for medical equipment brands, made to your specifications and quality requirements at our plants in Nuevo León.
What We Build for Medical Equipment Brands
We work from your drawings, bill of materials, and test requirements. Depending on your program, we can take on:
Boards mounted, wired, and integrated into the modules your equipment needs.
Final assembly of the unit inside its enclosure, ready for testing.
Internal wiring and cables built to your drawings.
Units tested against your procedures before they leave our plant.
Packed to your requirements and shipped from Mexico to your customers or warehouse.
Built to Your Quality Requirements
Medical equipment brands set strict requirements, and our job is to meet them on the production floor. Every program starts with a structured launch using APQP, PFMEA, SPC, and PPAP, so the process is defined and validated before volume production begins.
From there, we build to your specifications, follow the documentation your team defines, and test units against your procedures.

Why Medical Equipment Brands Work With Shelmex
- Manufacturing since 1996: companies from around 30 countries trust our plants in Mexico.
- Several processes, one partner: electronics, wiring, assembly, and testing under one roof, so fewer suppliers handle your product.
- From prototype to production: we can build prototypes before moving into volume production.
- Close to the United States: our plants in Nuevo León are about two hours from the Texas border.
