PARTNER WITH US






DHIO Research worked with OEMs, Tier-1, (and lower) suppliers of auto/aero/general engineering industry in collaborative engineering services, research and development in Design (3D, 2D, drafting), analysis (FEA/ CAE/DOE/, and process modeling (of manufacturing processes).
DHIO has a team of experts with FEA Analysts, Metallurgists, Manufacturing Process Experts, Optimisation Specialist and Tool & Die Designers with decades of experience in complex engineering Simulation based services in product/process/ material design, redesign, engineering reverse engineering, analysis and optimization to save money, material and time.
DHIO is conducting a variety of analysis for industry covering the interaction of thermal, stress, and material effects.
The objective of the analysis have been:
1. Re-design of the component / system
2. Analysis (for failure or redesign) of the system
3. Inducting new material for the design
4. Process re-engineering
5. Development of analysis / certification / virtual proofing procedures.
