• Biocompatibility: Medical-grade aluminum (paired with appropriate surface treatments) meets ISO 10993 standards, ensuring it’s non-toxic and non-irritating when in contact with human tissue—critical for devices like surgical forceps or implantable accessories.

• Sterilization Resistance: Aluminum withstands repeated exposure to autoclaving (121°C, 15 psi), ethylene oxide (EtO) gas, and chemical sterilants without warping or degradation, maintaining part integrity over thousands of cycles.

• Lightweight Durability: Aluminum’s high strength-to-weight ratio reduces the weight of handheld devices (e.g., ultrasound probes, dental tools) by 30-40% compared to steel, minimizing clinician fatigue during long procedures.

• Precision for Miniaturization: With CNC machining, we can create micro-scale aluminum parts (down to 0.1mm feature sizes) for minimally invasive devices (e.g., laparoscopic instruments, catheter components) where space is extremely limited.

1. Design Collaboration: Our engineering team works with you to refine CAD models (compatible with SolidWorks, AutoCAD) to optimize for manufacturability, sterility, and device integration. We also conduct DFM (Design for Manufacturability) reviews to reduce costs and lead times.

2. Material Sourcing: We use only medical-grade aluminum (certified with material test reports, MTRs) from trusted suppliers, ensuring compliance with FDA 21 CFR Part 820 and ISO 13485.

3. Precision Machining: Our state-of-the-art CNC machines (Fanuc, Mazak) with climate-controlled environments deliver consistent accuracy, even for complex geometries like internal channels or micro-threads. We use dedicated tooling for medical parts to avoid cross-contamination.

4. Medical-Grade Finishing: Surface treatments are tailored to device needs, including:

• Electropolishing: Creates a smooth, microbe-resistant surface (reduces bacteria adhesion by 60%).

• Type III Anodizing: Provides a hard, wear-resistant coating (ideal for surgical tools).

• Passivation: Enhances corrosion resistance for parts exposed to bodily fluids.

5. Quality & Regulatory Compliance: Every part undergoes 100% inspection using CMM (Coordinate Measuring Machines) and optical inspection systems to verify tolerances. We also provide full documentation, including:

• Certificate of Compliance (CoC)

• Batch traceability records

• Sterilization validation reports (when applicable)

• Rapid Prototyping: Get functional prototypes in 3-7 days to accelerate your device development timeline.

• High-Volume Production: Scale from 100 to 100,000+ units/month with consistent quality.

• Regulatory Expertise: Our team understands FDA, CE, and ISO 13485 requirements, ensuring your parts meet global market access standards.
