🔬
Prototype & Testing
Physical prototype coordination, in-field instrumented testing, strain gauge surveys, and full test reports with pass/fail criteria against spec sheets.

Our Engineering Process

A proven 3-step methodology that takes every project from requirements to road-ready in record time.

01
Requirements & Scope
We capture payload targets, operating environments, regulatory constraints, and integration requirements with your operations team before a single line is drawn.
02
Concept & Architecture
Multiple design directions are explored using 2D sketches and early 3D layouts. Packaging, access, and maintainability are validated at this stage to avoid costly rework later.
03
Detailed Engineering
Full parametric CAD models, FEA, CFD, and drivetrain simulations. All materials, welds, fastener specs, and tolerances are finalized with GD&T-annotated drawings.

SEM, EDX & Material Characterization

In-house and partner-lab capabilities to validate every material and weld before it goes near a chassis.

Scanning Electron Microscopy (SEM)
High-resolution surface and cross-section imaging to detect micro-cracks, porosity, and inclusion defects in weld beads, castings, and rolled sections. Essential for failure analysis and quality assurance on safety-critical vehicle components.
Fracture Analysis Weld Inspection Porosity Detection
Energy Dispersive X-Ray (EDX)
Elemental composition mapping coupled with SEM imaging to identify alloy grades, coating integrity, and contamination sources at micron scale. Used to verify raw material certifications and diagnose corrosion pathways in multi-axle structural members.
Elemental Mapping Alloy Verification Corrosion Diagnosis
Material Characterization
Full mechanical characterisation: tensile strength, yield point, elongation, Charpy impact, Rockwell/Brinell hardness, and fatigue life testing on steel plates, tubes, and forgings. All tests conducted against IS, ASTM, DIN, and EN standards with traceable certification.
Tensile & Yield Hardness Testing Impact & Fatigue

Finite Element Analysis

Structural simulation of ACU shelter assemblies — validating every load path before fabrication begins.

65 TR 65 TR ACU shelter structural frame — FEA model
65 TR ACU Shelter Structure
Full structural FEA of the 65 TR air conditioning unit shelter frame. Load paths through the base chassis, corner posts, and roof cross-members are solved for transit shock, lifting, and operational dead load — with member sizing driven directly by the stress results.

120 TR 120 TR ACU shelter assembly — panelled enclosure
120 TR ACU Shelter Structure
Scaled-up shelter for the 120 TR unit, analysed as a complete panelled enclosure. The heavier condenser bank and larger roof apertures shift the stiffness distribution, so the base frame and lifting points are re-solved rather than scaled from the 65 TR design.

Why we simulate before we cut steel
Running the analysis first means member sizes are set by the actual stress distribution rather than by rule of thumb — which typically removes weight from an over-built design and adds it exactly where the model says it is needed. Every load case is documented and handed over with the fabrication drawings.
