Core Competencies
Engineering &
Engineering &
Design Services
End-to-end capability from initial concept to complete manufacturing-ready documentation and photorealistic visualization.
01
3D Modeling & Assemblies
Extensive expertise in 3D modeling of large assemblies and complex mechanisms using SolidWorks and Autodesk Inventor. Movement simulation validates optimal functionality before a single drawing is produced.
02
Product Development
Full product lifecycle from concept to manufacturing, leveraging deep knowledge of materials, sheet metal properties and manufacturing possibilities. The result: analytical construction drawings that enable the full construction of the final product.
03
3D Rendering & Visualization
Photorealistic product visualization using KeyShot and 3D Studio MAX. Dynamic section views, exploded assemblies, and product brochures — high-end rendering that communicates engineering clearly and drives effective product advertising.
04
Mold Design
Precision casting mold design where every part interlocks seamlessly — cast with impeccable accuracy and consistent results. Geometry optimized to minimize final processing and finishing time.
05
Technical Drawings
Complete engineering documentation: construction drawings, data sheets, maintenance manuals, and assembly instructions. ISO-standard, fully dimensioned, and ready for direct production use.
06
Stress Analysis & Simulation
Finite element analysis and motion simulation to validate structural integrity and mechanism behaviour before committing to production. Reduce iterations, reduce costs.

Delivered Projects
A selection of real projects — from complex industrial machinery to precision consumer products — delivered to specification, on time.
02
Mold Design & Cast-Iron
Precision casting molds where every part interlocks seamlessly — plus CNC post-processing and FANUC programs for cast-iron components.
03
Construction Machinery R&D
R&D design of heavy equipment such as Mobile Batch Concrete Units and Horizontal Vibrated Feeders — large mechanical assemblies under strict manufacturing constraints.
04
Prototyping & Product Development
From concept sketch through movement simulation to 3D-printed prototypes — analytical construction drawings that enable the full build of the final product.
05
Brochures, Renders & Client Work
Photorealistic KeyShot visualization for brochures, product advertising, and international freelance deliverables — backed by a perfect 5.0/5.0 across 54 reviews.
