CAD Services for Manufacturing, Prototyping & Production
Professional CAD drafting and modeling services engineered specifically for CNC machining, injection molding, sheet metal fabrication, additive manufacturing, and precision cutting processes.
At NPDCAD, we create manufacturing-ready CAD files optimized for the exact production method you use—whether it's CNC milling, molding, sheet metal forming, laser cutting, 3D printing, or assembly fabrication. Our engineering-focused approach ensures every model and drawing includes the correct geometry, wall thicknesses, draft angles, tolerances, hole sizes, and material considerations needed for smooth, error-free production.
Manufacturing-grade CAD • Accurate geometry • Optimized for real-world fabrication
CAD Services for Manufacturing Use Cases
CAD for CNC Machining
Our CNC-ready CAD models and engineering drawings are built for precise machining, whether you're producing simple brackets or complex multi-axis components. We design models that accommodate cutter paths, machining clearances, tool approach, fillet radii, and manufacturability guidelines.
What We Deliver:
- CNC-ready 3D CAD models
- Fully dimensioned 2D machining drawings
- GD&T callouts for fit, form, and function
- Optimized geometry for milling, turning, and multi-axis machining
CAD for Injection Molding
We create CAD designs that follow molding best practices, ensuring manufacturable parts with proper draft angles, uniform wall thickness, rib reinforcement, gate-friendly geometry, and clean parting lines.
What We Deliver:
- Mold-ready 3D CAD models
- Draft analysis & wall-thickness optimization
- Rib & boss design
- Split-line and core/cavity-ready geometry
CAD for Sheet Metal Fabrication
Our CAD services support sheet metal bending, laser cutting, forming, and assembly operations. We deliver flat patterns, bend tables, K-factors, and detailed fabrication drawings.
What We Deliver:
- Sheet metal 3D models
- Flat patterns (DXF/DWG for cutting)
- Bend lines, radii & tolerances
- Hardware callouts & PEM detail support
CAD for 3D Printing
We design 3D printable parts optimized for FDM, SLA, SLS, MJF, and resin printing. Our models focus on strength, printability, wall thickness, support structure minimization, and layer orientation.
What We Deliver:
- STL & 3MF files
- Solid & hollow models
- Print-ready geometry
- Prototype optimization
CAD for Laser Cutting & Waterjet Cutting
We create 2D vector CAD files and simplified 3D models ready for plasma cutting, laser cutting, and waterjet operations. All geometry is clean, closed-loop, and optimized for cutting tolerance.
What We Deliver:
- DXF/DWG cutting files
- Flat profiles & nested layouts
- Kerf compensation
- Bend reliefs for formed parts
Assembly Drawings & Exploded Views
We produce assembly-level CAD documentation with exploded views, BOMs (Bill of Materials), fastener callouts, and step-by-step assembly visualization.
What We Deliver:
- Exploded diagrams
- Part-to-part interface details
- BOMs & assembly tables
- Sequence illustrations
Tolerance & GD&T Drafting Services
Our GD&T drafting services ensure your parts meet critical fit, form, and function requirements. We apply datums, tolerance zones, feature control frames, and dimensional constraints that match industry standards.
What We Deliver:
- Full GD&T annotation
- Tolerance stack analysis
- Precision machining documentation
- ASME Y14.5-compliant drawings
What File Formats We Deliver
We provide all major CAD formats for manufacturing, including:
- STEP (.step / .stp)
- IGES (.igs / .iges)
- STL, 3MF
- DWG, DXF
- SLDPRT, SLDASM
- F3D, IPT, IAM
- OBJ, Parasolid
Why CAD Must Match the Manufacturing Method
Different production processes require different CAD approaches.
We ensure your CAD files fit the exact needs of:
- CNC machining tolerances
- Mold flow and cooling requirements
- Sheet metal forming limitations
- Additive manufacturing strengths/weaknesses
- Laser/waterjet kerf and material behavior
- Assembly order and part relationships
This reduces manufacturing errors, saves time, lowers cost, and speeds up your time to market.
