Mechanical DFM Services

Streamlining Product Designs for Scalable, Cost-Efficient Manufacturing

At SunMan Technology, our Design for Manufacturability (DFM) services help you transition from prototype to production with confidence. By integrating DFM principles early in the design cycle, we ensure your mechanical components and assemblies are not only functional but also ready for efficient, repeatable, and cost-effective manufacturing.

Whether you’re building a medical device, an aerospace subsystem, a robotic mechanism, or an IoT product, our mechanical DFM team helps you avoid production pitfalls—saving time, reducing rework, and lowering costs.

What We Deliver

Optimized Mechanical Designs

We evaluate geometry, tolerances, materials, and assembly methods to ensure each component is manufacturable with your target production process—be it CNC machining, injection molding, die casting, 3D printing, or sheet metal fabrication.

Manufacturing Method Alignment

Our engineers tailor mechanical designs to suit your manufacturing environment and vendor capabilities, improving yield rates and minimizing tooling revisions.

Assembly-Aware Engineering

We simplify multi-part assemblies for ease of integration, fasteners access, and reduced part count, boosting assembly-line efficiency.

Cost & Risk Reduction

Through DFM, we proactively eliminate design features that may increase tooling costs, lead times, or QA failures—reducing your product’s cost of goods sold (COGS).

Detailed Engineering Documentation

From updated CAD files and BOMs to 2D drawings with GD&T annotations, we prepare all documentation needed to move seamlessly into production.

Mechanical DFM Applications

• Medical Devices: Ergonomic enclosures, disposable components, molded biocompatible parts
• Robotics: Joint assemblies, mounts, brackets, and gear housings
• Aerospace: Lightweight, high-tolerance components for flight-critical systems
• IoT Devices: Enclosures, thermal interfaces, clips, and PCB mechanical interfaces
• Consumer & Industrial Products: Structural housings, fastener schemes, snap-fit features

DFM Process at SunMan Technology

1. Design Review & Risk Assessment
   In-depth analysis of CAD files to flag manufacturability, tolerance stack-ups, or complexity issues.
2. Material & Process Matching
   Recommendations for optimal material/process combinations for scalability and performance.
3. Feature Optimization
   Design adjustments to reduce undercuts, thin walls, non-uniform surfaces, or complex assembly steps.
4. Feedback Loop with Manufacturing Partners
   Coordination with your contract manufacturers or ours to validate proposed design improvements.
5. Documentation for Fabrication
   Finalized models, engineering drawings, and design reports ready for production.
