Precision Assembly &
Contract Manufacturing
Two divisions — CNC machining and electromechanical assembly — built for U.S. OEMs. Same timezone. Same standards. Two hours from the border.
Two Divisions, One Standard of Excellence
Whether your project demands precision-machined components or complex electromechanical assemblies, you work with a team that understands tolerances, timelines, and the cost of getting either one wrong.
Contract Manufacturing
CNC Precision Machining — Tight Tolerances, Reliable Output
GPW's Contract Manufacturing division delivers precision CNC machining for components that demand consistency at scale. From prototype runs to production volumes, we machine parts to specification across metals and engineering-grade plastics.
Electromechanical Assembly
Complex Assembly for U.S. OEMs — From BOM to Boxed Product
GPW's Electromechanical Assembly division is built for one thing: taking your bill of materials and delivering a fully assembled, tested, and packaged product. This is not board-level assembly — this is full system integration.
Your Nearshore Advantage — 150 Miles from the Border
Tariff exposure, 8-to-12-week ocean freight lead times, and timezone gaps that turn a simple engineering question into a 48-hour email chain — these are problems that nearshoring to Monterrey eliminates.
Eight Industries, One Quality Standard
Our assembly processes adapt to your industry's requirements — not the other way around. The same engineering-driven quality system governs every build.
Engineered for OEMs Who Demand More
Most contract manufacturers in Mexico focus on high-volume board-level work. GPW is different. We are assembly-first — built for the complex, multi-step electromechanical builds that single-process shops cannot handle.
Assembly-First Specialization
We do not fabricate PCBAs. We assemble complete products — mechanical, electrical, cabling, and testing — under one program manager who speaks your language and works your hours.
Right-Sized for Tier 1 & Tier 2 OEMs
Large enough to handle production volumes. Agile enough to adapt when your BOM changes mid-run. You are not account number 500 at a mega-EMS — you are a partner with a dedicated team.
Engineering-Driven Quality
Every project starts with a DFM review. Every assembly follows IPC-standard workmanship criteria. Every unit passes end-of-line functional testing before it ships.
Speed That Matters
48-hour RFQ response. First article builds in 2–3 weeks. Production ramp in 4–6 weeks. We move at the speed your supply chain demands.
