5 Best Mechanical Engineering in Delhi (2026)

XiLiR Technologies runs out of Dabri, offering final-year and postgraduate engineering project help across mechanical, electronics, and computer science disciplines, alongside research paper writing and publication support. It's aimed squarely at students rather than industrial clients, and reviewers, mostly B.Tech and M.Tech students, describe late-night help finishing projects before submission deadlines. The business also runs a training arm and sells pre-built project kits through its site.

Mohindra Mechanical Works, trading as Mohindra Engineering Company, manufactures printing and packaging machinery out of Khyala: rotogravure and flexographic printing machines, slitting machines, and lamination and coating equipment. It's a real production-line manufacturer, not a services shop, and reviewers who bought machines describe clean installations, follow-up checks days after delivery, and strong build quality across different equipment types.

Hydrotech Engineering Works operates a machine workshop in Sultanpuri, manufacturing hydraulic equipment and plastic injection molding machines, including toggle-type presses and grip-cover machines. Reviewers describe buying multiple machines over time and receiving hands-on setup and training, in one case with the team traveling to Kerala to assemble and train a buyer's staff on-site.

This Okhla-based studio, trading online as My Cad Engineer, specializes in mechanical CAD design using CATIA V5, covering plastic, casting, forging, and sheet-metal part design, plus 3D printing services. Its site claims over 10 years of CAD design experience, and reviewers, a mix of engineering students and small businesses, describe detailed, accurate modeling work delivered on tight timelines.

This is the Department of Mechanical Engineering at IIT Delhi, an academic department rather than a commercial engineering firm. Reviewers, mostly students, alumni, and campus visitors, describe well-maintained labs and equipment, along with faculty regarded as among the strongest in the country for production and mechanical engineering research. It's included here because it shows up prominently in Delhi's mechanical engineering search results, not because it takes on commercial contracting work.
