Our Evolution From Precision Tooling to Turnkey Automation
A quarter-century journey of heavy engineering craft, technological investments, and zero-compromise precision in Pune.
Workshop Inception in Pune
Founded as a precision tooling and fixture workshop in Dehu Gaon, supplying high-tolerance components to Pune's automotive belt.
CNC & Heavy Machining Expansion
Invested in in-house VMC and heavy turning machinery to deliver complete welded and machined sub-assemblies under one roof.
Induction Hardening Specialization
Engineered specialized vertical scanning induction hardening cells and custom copper coil tooling for Tier-1 gear manufacturers.
Turnkey SPM Automation & Global Supply
Delivering complete custom machines with PLC automation, safety enclosures, and 100% in-house FAT live testing for global manufacturers.
"To be the most trusted and reliable partner for custom machine design and manufacturing."
"To provide our customers with high-quality, practical, and long-lasting machine solutions at the best value."

The 4 In-House Manufacturing Pillars
Why leading Tier-1 automotive and heavy equipment manufacturers trust Three Star Enterprises with their mission-critical machinery.
Smart, Practical 3D Design
Every machine model is built for heavy continuous industrial use, easy maintenance access, and ergonomic operator safety.
100% In-House Manufacturing
Steel fabrication, precision CNC milling, electrical panel wiring, and PLC logic are performed completely within our Pune workshop.
Full Workshop FAT Live Trials
Before shipping, we run the completed machine with your actual raw parts to verify cycle times, hardness depth, and tolerances.
Single-Point Accountability
Direct communication with the engineers designing and building your machine — zero subcontracting delays or lost details.
How We Build Your Machine: 5-Stage Controlled Protocol
A transparent, systematic route from your raw drawings to a tested, production-ready machine on your factory floor.
Requirement & Blueprint Study
We review your part drawings, material grades, production throughput, and dimensional tolerances.
3D CAD & Motion Simulation
Complete SolidWorks 3D models and assembly kinematic simulations verified before cutting any metal.
Precision CNC Machining
In-house heavy CNC milling, turning, boring, and structural frame fabrication to tight micrometric tolerances.
Electrical & PLC Integration
Servo motor wiring, quench manifold routing, safety interlocks, and custom HMI touch-screen programming.
100% FAT Live Part Testing
Rigorous Factory Acceptance Testing (FAT) with actual client parts to prove cycle times and surface quality.
Built in Pune. Engineered for Zero Downtime.
“Every machine, conveyor, and automation system leaving our workshop is built with pride, thoroughly tested with real materials, and engineered to run reliably year after year on active factory floors.”
