Mechanical Design Services in India, Built on Metrology-Grade Accuracy
Physical to Production-Ready CAD
APJ 3D Design Solutions India is a Hosur-based engineering services company that helps manufacturers move from a physical part, a legacy drawing, or a rough concept to a production-ready CAD model and validated design. Our core work spans reverse engineering, 3D scanning, parametric CAD reconstruction, and multi-physics CAE simulation for automotive, rail, aerospace, and heavy-machinery OEMs and Tier-1 suppliers. Rather than generic drafting, we combine high-precision optical and CMM metrology with experienced design engineers, so every model we hand back is both dimensionally accurate and manufacturing-ready.
1,000+ Precision Projects Delivered
Manufacturers work with APJ 3D because we shorten the distance between "we have a part or an idea" and "we have a verified, production-ready design." Our teams have delivered over 1,000 precision engineering projects, and we structure every engagement around right-first-time outputs — cutting down redesign cycles, prototype scrap, and tooling rework. To see how this applies to your product, read more about our team and capabilities, or get in touch to discuss a project.
Full-Chain Scan-to-CAD vs. Piecemeal Services
Manufacturers often start by hiring a scanning vendor and a CAD vendor separately. APJ 3D runs the full scan-to-CAD chain as one accountable engagement. Here is how the two approaches compare on a typical reverse-engineering project.
