- Medical Devices: As non-magnetic, lightweight structural components for diagnostic imaging and surgical robots
· Production Process Introduction
- Design & Engineering Validation: Our engineering team collaborates with you to refine CAD models, optimize for weight reduction and structural integrity, and validate load-bearing performance via finite element analysis (FEA).
- Raw Material Preparation: Premium aluminum billets are sourced from certified suppliers, with full spectrometric analysis to verify material composition and mechanical properties.
- 5-Axis CNC Machining: State-of-the-art 5-axis milling machines execute complex 3D machining operations to create deep cavities, contoured surfaces, and precision hole features in a single setup, minimizing setup error and maximizing accuracy.
- Deburring & Finishing: Components undergo meticulous mechanical and manual deburring to ensure burr-free edges and smooth internal surfaces, followed by optional surface treatment.
- Comprehensive Quality Inspection: 100% inspection is performed via CMM (Coordinate Measuring Machine), 3D scanning, and visual inspection to verify compliance with all dimensional and functional specifications.
- Final Packaging: Components are cleaned, wrapped in anti-static foam, and secured in custom-cut corrugated boxes to prevent scratching and damage during transit.
· Packaging and Shipping Methods
- Standard Packaging: Each bracket is individually wrapped in anti-static PE foam and placed in a custom-cut corrugated box, with additional cushioning for bulk orders to prevent movement and surface damage.
- Shipping Options:
- Express Delivery (3–7 Business Days): DHL/FedEx/UPS for prototypes and small batch orders, with full tracking and delivery confirmation provided.
- Standard Sea Freight (25–40 Business Days): Cost-effective FCL/LCL options for large-volume production orders, with full customs documentation and logistics support included.
- Custom Packaging: Branded labeling, barcoding, serialized part marking, and custom foam inserts are available to align with your inventory management and brand guidelines.

· Frequently Asked Questions (FAQ)
What is your Minimum Order Quantity (MOQ)?
Our MOQ is highly flexible: 1 piece for prototyping and custom one-off projects, with volume pricing starting at 20+ pieces for production runs. We specialize in both low-volume, high-mix custom manufacturing and large-scale OEM production.
What are your typical lead times?
- Prototyping: 10–15 business days from final CAD design approval to shipment.
- Mass Production: 20–35 business days, varying based on order volume, design complexity, and surface treatment requirements.
- Rush Service: Expedited production (5–7 days for prototypes) is available upon request for an additional fee.
Can you accommodate custom modifications?
Absolutely. We offer full end-to-end customization to meet your exact application requirements:
- Material Customization: Alternative materials including stainless steel, titanium, or magnesium alloy for specialized strength, corrosion resistance, or weight reduction needs.
- Design Modifications: Custom dimensional adjustments, added features such as mounting tabs, fluid passages, or sensor mounting points, and modified load-bearing geometries.
- Surface Finish Options: Custom anodizing (clear, black, or colored), powder coating, or chromate conversion coating to enhance corrosion resistance and aesthetic appeal.
- Branding & Traceability: Laser engraving of part numbers, logos, or serial numbers for full product traceability.
