Mentco is a full-service precision CNC machine shop that produces high-quality machined parts and sub-assemblies built to customer specs. We run our manufacturing operations out of Mumbai, India, with headquarters and warehousing in San Antonio, Texas — giving customers the best of both worlds: cost-effective production without sacrificing reliable lead times or hands-on service. Our specialty is precision CNC turning and milling, handling everything from one-off prototypes to full production runs for OEMs in semiconductor, aerospace, energy, automation, medical, transportation, and industrial machinery. We don't stop at machining — we manage sourcing, finishing, assembly, packaging, and logistics too, so you get one dependable partner instead of five vendors. Investing In Precious Metals
