From AS9100-certified aerospace assemblies and IATF 16949 automotive design to lean cell manufacturing, IBR-compliant boilers, ASHRAE-grade HVAC, bespoke SPMs, and precision sheet metal — DID Solution delivers integrated engineering that performs under audit, on the shop floor, and in the field.
Bridging Theoretical Design with Shop-Floor Reality.
At DID Solution, we don't just deliver drawings — we engineer industrial certainty. Based in Chennai, India, we are a multi-disciplinary engineering design firm specialising in high-complexity sectors where precision is the baseline and failure is not an option.

Our Operating Domain
Our team operates at the intersection of Mechanical, Thermal, and Electronic engineering — providing a seamless transition from initial concept to manufacture-ready documentation. We serve procurement officers, plant managers, and lead engineers who need engineering output that performs as well on the floor as it does in a review meeting.

Why Engineering Leaders Choose Us
Multi-Domain Fluency
Unlike niche firms, we bridge the gap between domains. Whether integrating an ECU into an automotive chassis or designing a thermal-efficient industrial boiler, our cross-functional expertise eliminates "handoff friction" — one team, full discipline coverage.
Compliance-First Culture
We don't design in a vacuum. Every deliverable is benchmarked against global standards — AS9100 for Aerospace, IATF 16949 for Automotive, ASME/IBR for Thermal Systems, and ASHRAE for MEP — so your design clears regulatory review without redesign loops.
Simulation-Driven Accuracy
By utilising advanced FEA and CFD early in the design cycle, we identify and resolve structural and thermal bottlenecks before they reach the prototype stage — catching failures in the model, not on the shop floor.
Manufacture-Ready Deliverables
We don't hand over concept sketches. Our outputs are fully annotated CAD models, GD&T drawing packages, and simulation reports that go directly to production, procurement, or statutory inspection — zero interpretation required.
Core Philosophy
"To empower global industries with design architectures that are as robust in practice as they are elegant in theory."
We believe that great engineering is invisible. It's the reliability of a flight-critical component, the efficiency of a U-shaped manufacturing cell, and the absolute accuracy of a QMS-compliant documentation package. At DID Solution, we provide the technical backbone that allows your business to scale with confidence.

Our Services
Engineering solutions built for industry.
Every engagement starts with your specification and ends with manufacture-ready drawings, validated designs, and full compliance documentation.
01 — QMS Documentation
Audit-Ready QMS Documentation
Your QMS should pass the audit before the auditor arrives. We engineer documentation systems — SOPs, control plans, PFMEA, work instructions — structured to AS9100 Rev D, ISO 9001:2015, and IATF 16949:2016 clause hierarchies, eliminating non-conformance findings at source.
→ AS9100 / ISO 9001 / IATF 16949 gap analysis & clause mapping
→ APQP, PPAP Level 3–5 documentation packages
→ FMEA (Design & Process), Control Plans, MSA, SPC setup
From body-in-white stampings to EV battery thermal enclosures, we deliver designs that survive the press tool, the crash test, and the production line. Our DFM-first methodology on interior and exterior components cuts tooling rework cycles by integrating manufacturing constraints from day one.
→ BIW structural analysis: roof crush, side impact, torsional rigidity
Flight-critical geometry demands tolerances that leave no margin for interpretation. We design and analyse aerospace components — brackets, structural ribs, control linkages, jigs & fixtures — under AS9100 Rev D protocols, delivering FEA-validated packages that compress certification lead time.
A poorly sequenced manufacturing cell bleeds Takt time and inflates WIP inventory silently. We engineer lean cell layouts with value-stream-mapped material flow, ergonomic workstation sequencing, and automated conveyance design — cutting non-value-added motion before the first tool is bolted down.
→ Takt-time calculation, line balancing & OEE improvement mapping
→ 2D/3D lean layout design with spaghetti-diagram & flow analysis
Cleanroom qualification starts with the HVAC design, not the validation protocol. We engineer ASHRAE 62.1 / 90.1-compliant mechanical systems, full MEP coordination packages, and ISO 14644-class cleanroom air distribution layouts — delivering construction-ready Revit/AutoCAD drawings, BOQ, and commissioning checklists in a single handover package.
→ Cleanroom ISO 14644 air change rate, pressurisation & filtration design
Boiler compliance isn't a checklist — it's a thermal, structural, and regulatory discipline. We deliver IBR, ASME Section I & VIII, and IS:2825-compliant pressure vessel engineering with CFD-validated combustion models, eliminating design rejections at the statutory inspection stage.
→ IBR & ASME Sec. I / VIII design calculations & statutory approval drawings
Off-the-shelf machines don't solve non-standard problems. We design Special Purpose Machines from blank-sheet mechanical concept through PLC-integrated control architecture — delivering CE-marked, ISO 13849-validated systems with sub-4-second cycle times and full FMEA-backed safety circuits.
Precision Tool & Die Design — High-Performance Tooling for Complex Manufacturing
We specialise in the end-to-end design and engineering of high-precision tools and dies tailored for the automotive, aerospace, and industrial sectors. Our approach integrates advanced CAD/CAM methodologies with material science to ensure your tooling survives millions of cycles with zero compromise on part accuracy.
→ Progressive Die Design: multi-station dies for high-speed production & complex metal forming
→ Injection Molds: high-precision molds for complex plastic components with optimised cooling channels
→ Poka-Yoke Integrated Tooling: smart dies with built-in error-proofing to eliminate defects at source
→ Jigs & Fixtures: custom holding & positioning devices to streamline assembly and inspection
→ Material Optimisation: high-grade tool steels & coatings for maximum wear resistance & minimal downtime
