– Conduct Design for Manufacturability (DFM) analysis to optimize production efficiency and cost-effectiveness.
2. CAD/CAM Integration & Prototyping
– Convert your designs into precise CAD models using SolidWorks/AutoCAD, ensuring compatibility with CNC machining and laser cutting.
– Develop functional prototypes with rapid sheet metal prototyping services (10-20 business days typical).
3. Material Selection & Approval
– Recommend optimal materials (e.g., stainless steel, aluminum) based on your application’s strength, corrosion resistance, and budget.
4. Production & Quality Validation
– Execute full-scale manufacturing with ISO 9001-certified processes.
– Perform in-process inspections using CMM measurement and surface finish testing.
5. Delivery & Post-Sales Support
– Coordinate global logistics via air/sea freight with real-time tracking.
– Provide after-sales support on all products.
Result: 30% faster turnaround than industry benchmarks, with zero compromise on precision.
