CAD Design & Prototyping Services in India
Alpha Grade Industries provides professional CAD design services for industrial manufacturers, OEMs, and product developers across India. Based in Delhi NCR, we support clients with accurate design modeling, technical drafting, and structured product development workflows.
Our expertise in industrial CAD design allows us to convert product concepts, sketches, and ideas into production-ready engineering models. From 2D drafting to 3D modeling and prototype development, we help businesses move from concept to manufacturing with clarity and precision.
We specialize in product design and prototyping, ensuring every component is optimized for functionality, manufacturability, and cost-efficiency.
Our CAD & Engineering Capabilities
Our engineering team provides comprehensive digital design and modeling solutions.
Core Services Include:
- 3D CAD modeling services
- CAD drafting services
- 2D CAD drafting services
- 3D product modeling
- CAD drawing conversion services
- Reverse engineering services
- Design for manufacturing services
We create accurate technical drawings, assembly models, exploded views, and detailed production documentation required for industrial manufacturing.
For clients moving toward physical production, our designs are directly aligned with our Precision Turned Components, Sheet Metal Fabrication, and Injection Molding Services divisions to ensure a smooth production transition.
3D Modeling & Product Development
We offer structured 3D CAD modeling services for components, assemblies, and full product systems.
Our Process Includes:
- Concept Understanding: We analyze product requirements, functional goals, and application environment.
- 3D Product Modeling: Using professional CAD software, we develop detailed 3D product models with accurate dimensions and tolerances.
- Assembly Simulation: Component interactions and assembly fit are validated digitally before manufacturing.
- Design Optimization: Through design for manufacturing services, we simplify geometries, optimize tolerances, and reduce production costs.
This ensures smooth handover to machining, fabrication, or molding processes.
Prototype Design & Development
Before bulk production, validation is critical. We provide reliable prototype design services and rapid development support.
Our Prototyping Capabilities:
- Rapid prototyping services
- Prototype manufacturing services
- 3D printing prototype services
- Industrial prototype development
- Plastic and metal prototype validation
Prototypes allow clients to evaluate functionality, assembly fit, and structural strength before investing in full-scale production.
For plastic product development, prototypes seamlessly transition into production through our Injection Molding Services team.
Reverse Engineering & Drawing Conversion
We assist clients who have physical samples but lack technical drawings.
Our services include:
- Reverse engineering services
- CAD drawing conversion services
- 2D to 3D model conversion
- Legacy drawing digitization
Using measurement and modeling techniques, we recreate accurate CAD models that can be used for manufacturing and quality control.
These designs are production-ready and compatible with our machining and fabrication divisions.
Engineering-Driven CAD Design & Prototyping for Smart Manufacturing.
Design for Manufacturing (DFM)
One of the most important aspects of engineering design is manufacturability.
Through our design for manufacturing services, we:
- Optimize material selection
- Adjust tolerances for cost efficiency
- Simplify complex geometries
- Improve assembly feasibility
- Reduce material waste
This ensures that components designed digitally can be efficiently produced by our Precision Turned Components and Sheet Metal Fabrication teams without unnecessary rework.
Industries We Serve
Our CAD design services support multiple sectors:
- Automotive: Component modeling, assembly design, and prototype validation.
- Electrical & Electronics: Enclosure design, plastic housings, and mounting systems.
- Industrial Machinery: Machine component modeling and structural system design.
- OEM Manufacturers: Full product design and prototyping support.
Workflow Integration with Manufacturing
What makes our CAD division powerful is its integration with real manufacturing.
Our design outputs are directly compatible with:
- CNC machining and Precision Turned Components
- Structural and enclosure production in Sheet Metal Fabrication
- Plastic component manufacturing in Injection Molding Services
This reduces design-to-production gaps and accelerates project timelines.
Prototype to Production Transition
After design validation and prototype approval, we support clients through full-scale production.
Transition Steps:
- Final CAD approval
- Technical documentation release
- Tooling and mold preparation
- Trial production runs
- Bulk manufacturing coordination
This integrated workflow makes us a reliable partner for complete product lifecycle development.
