Concept & design
From clean-sheet concept to detailed drawings. Requirements are translated into buildable specifications with explicit tolerance and process notes.

What we do and how we do it
Engineering, production and quality — deliberately in-house.
Our capability stack is organised around three integrated pillars: Engineering, Manufacturing, and Quality. Keeping them under one roof is what makes tight tolerances and on-time delivery possible on low-volume defence work.
Pillar 01 · Engineering
Designs that can be built, priced fairly, and delivered on time.
Engineering is the gate that every job passes through — before costing, before routing. A buildable design with a defensible tolerance plan is the foundation of everything downstream.
E.02
DFM & tolerance analysis
Manufacturability assessed against our actual plant. Tolerance stack-up is formally analysed before release.
- Process capability mapping
- Stack-up analysis
- Fixture & jig design
E.03
Simulation (roadmap)
FEA for structural and thermal behaviour is being added as a partner capability — ready for strategic programmes in FY26–27.
- Static & modal FEA
- Thermal mapping
- Fatigue estimation
Pillar 02 · Manufacturing
A vertically integrated plant at Govindpur.
Machining, fabrication, welding, assembly and finishing sit inside one facility under one quality protocol. Nothing critical is shipped out to untraceable sub-tiers.
M.01
CNC machining
Turning, milling and multi-axis machining on calibrated equipment. Critical dimensions are verified in-process, not just at final inspection.
- 3-axis & 4-axis CNC
- Live-tool turning
- Hard-spec fixturing
M.02
Fabrication & welding
Sheet-metal fabrication, TIG/MIG welding and precision forming — all tracked against drawing revisions and certified weld procedures.
- Certified weld procedures
- Jig-controlled assembly
- Post-weld treatment
M.03
Surface treatment
Protective and functional finishes aligned to defence and marine specifications — corrosion, wear, appearance and signature control.
- Phosphating & passivation
- Powder coat & paint
- Black oxide & specialty finishes
M.04
Heat treatment (partner)
Hardening, tempering and stress-relief carried out through qualified heat-treatment partners with full material test records.
- Through-hardening
- Case-hardening
- Certified MTCs
Pillar 03 · Quality
Quality is built in, not inspected in.
Our quality function owns the declared grade. It has a veto at every gate — including commercial pressure — to ensure we don’t release what we can’t stand behind.
Q.01
In-process inspection
Quality is built in, not bolted on. Inspection stations sit inside the production flow, not only at the end.
- First-piece inspection
- Patrol checks
- Statistical sampling
Q.02
Metrology
Calibrated instruments across dimensional, form and surface-finish inspection — CMM capability is in the current-year plan.
- Height gauges & micrometers
- Roughness & profile
- CMM (FY26 plan)
Q.03
Traceability
Every batch is serialised. Material, machine, operator and inspection records are archived against the job number.
- Material test certificates
- Routing-card traceability
- Archived inspection records
What this adds up to
A supplier built to be boring — in the best possible way.
- No surprise schedule slips, because routing is realistic
- No quality incidents, because inspection sits inside the flow
- No mystery charges, because quotes are line-itemised
- No lost paperwork, because every batch is serialised
