Engineering training models make internal mechanisms visible. A sectioned gearbox teaches more about power transmission in five minutes than a chapter of diagrams, which is why cutaway and demonstration models remain standard equipment in engineering colleges, polytechnics and TVET institutes. Naugra Export manufactures and exports the complete range from Ambala, India.
Cutaway models - real components sectioned and finished so the internal construction is exposed, with cut faces painted to distinguish parts. Used for engines, gearboxes, pumps, valves, bearings and compressors.
Working models - motorised or hand-cranked so mechanisms can be operated and observed under motion. Used for theory of machines, kinematic linkages, cam and follower, gear trains and governors.
Demonstration models - simplified representations built to teach a single principle clearly rather than to replicate a real component.
Automotive - four-stroke and two-stroke petrol and diesel engine cutaways, gearbox and transmission assemblies, differential and axle models, clutch and braking system models, steering and suspension assemblies.
Theory of machines and mechanisms - gear train models, cam and follower apparatus, governor models, universal joint models, kinematic linkage sets, belt and chain drive models and flywheel apparatus.
Fluid machinery - centrifugal and reciprocating pump cutaways, turbine models including Pelton, Francis and Kaplan, valve cutaways and compressor sections.
Thermal engineering - boiler models, steam turbine sections, refrigeration and air conditioning cutaways, and heat exchanger sections.
Civil and structural - truss and frame models, bridge models, building construction sequence models and structural joint demonstration models.
Confirm whether a model is static or working, whether it is mounted on a stand or bench-top, whether the cut faces are colour-coded to a legend, and whether an explanatory chart and instruction manual are supplied. For working models, confirm the drive - hand-cranked models need no power supply and survive better in laboratories with unreliable electricity.
Naugra Export manufactures cutaway and working engineering models to standard and custom specification, and supplies complete engineering teaching laboratories for colleges and government tenders worldwide. Send your syllabus or tender BOQ for a compliant quotation.
