End-to-end CAD design services
End-to-end CAD design services, from concept and functional validation to detailed modeling for manufacturing. We develop complex 3D geometries, large assemblies, sheet metal parts, aesthetic surfaces, and cast or molded components. Our work includes dimensional tolerancing (GD&T), manufacturing-ready modeling, and adaptation to specific production technologies such as machining, injection, or casting. We also support multi-CAD collaboration, model conversion and repair, and simulation integration.
3D modeling for the rear fender of a tractor
Design the rear fender of a tractor from a hand-drawn reference shape, ensuring that the final form captures the intended aesthetic and functional outline.
Translate the hand-sketched contour into a precise 3D CAD model, maintaining the stylistic intent while ensuring compatibility with the tractor body.
The fender must be manufacturable from sheet metal, utilizing appropriate bending, stamping, or laser cutting processes.
Design the fender with integrated mounting points to allow secure attachment to the tractor frame using standard fasteners or welds.
Rear Fender Development – From Sketch to Manufacturable Design
Starting from the hand-drawn sketch, we generated the complex 3D geometry of the tractor’s rear fender, guided by Design for Manufacturing (DFM) principles to ensure production feasibility and efficiency.
Convert the hand-drawn profile into a detailed and manufacturable 3D surface model, preserving the intended aesthetic while adjusting for production constraints.
Introduce bend radii, reliefs, and draft angles where needed to simplify tooling and reduce material stress during forming.
Include precise mounting points and hole placements for fasteners or welding, ensuring easy and secure assembly to the tractor frame.
Fast deployment and fast prototyping, optimized shape and good manufacturability
3D Modeling for a tractor
Design the plastic hoods for a prototype tractor. The design must incorporate several critical functions
Integrated Features: The hood must seamlessly integrate headlights, an exhaust pipe, and an opening mechanism to allow easy access to the engine for maintenance.
Manufacturability & Assembly: All components must be designed with efficient manufacturing and ease of assembly in mind.
Structural Integrity: Particular attention must be given to structural rigidity, especially in the areas supporting the headlight bracket.
The bracket requires a firm and secure mounting point, ensuring durability under operational conditions.
Starting from the 3D scan of the tractor chassis, we generated the complex outer surface geometry of the plastic hood assembly.
Create high-fidelity surfaces that accurately follow the scanned geometry, ensuring perfect fitment and aesthetic continuity with the existing tractor structure.
Integrate assembly bosses, clips, and fastening points directly into the CAD design to allow efficient and repeatable assembly of all components.
Large plastic surfaces are reinforced with ribs, walls, and strategically placed support structures to prevent warping during both molding and real-world use.
Fast deployment and fast prototyping, optimized shape and very fast assembled.
Trunk side bracket design
Consolidate 2-piece welded assembly into a single, optimized part. Eliminate ultrasonic welding & reduce molds for simpler, faster manufacturing. Apply DFM for injection molding, targeting reduced mold complexity.
Redesigned 2-piece welded bracket into a single, integrated molded component.
Integrated Features: Combined functionalities of original parts into unified geometry.
Optimized for Single-Tool Molding: Designed for single mold ejection, minimizing complex actions (sliders/lifters) through careful consideration of draw, parting lines, & features.
Mass Reduction: Implemented design strategies for lower mass without compromising structural integrity.
Maintained Functional Interfaces: Ensured critical fixing points & interfaces were maintained/improved for stiffness & assembly.
Final CAD validated with DFM analysis & manufacturing partners.
Drastically reduced manufacturing complexity (single part vs. 2 + weld).
Decreased production cycle time (eliminated welding).
Lower tooling investment & maintenance (one mold vs. two + fixtures).
Simplified logistics & inventory (single part number).Improved part consistency & quality (no weld variation).
Reduced overall component mass through optimization.
Minimized mold actions (sliders/lifters), simplifying the mold & improving reliability.
IP Shroud Design
Re-engineer 2-part IP shroud into a single part via integrated living hinge.
Enable manufacturing from a single injection mold for simpler production.
Design to be molded 'open/flat', then fold like a book into final state.
Designed as a single, monolithic part, molded open/flat.
Folds along an engineered living hinge (like a book) to final 3D form.
FEA collaboration optimized living hinge for durability & form (open/closed).
DFM for living hinges ensured efficient single-tool molding & reliable folding.
Significant cost reduction (one mold vs. two) – lower tooling & maintenance.
Simplified assembly & servicing (single piece, book-folding design).
Improved aesthetics & fit (no gaps from separate parts when folded).
Reduced part count & inventory (single part from one mold).
Streamlined manufacturing workflow (no multi-part assembly).
