Precision You Can Trust – From Shenzhen to Silicon Valley

As a China-based custom injection molding factory serving clients across North America and Europe, we know one thing for certain: your FAI report isn’t paperwork—it’s your credibility.

Whether you’re launching a new smart wearable, a medical diagnostic housing, or an automotive interior component, the Full Dimensional Report is often the gatekeeper to production approval.

That’s why we don’t just “generate” an FAI—we engineer it with the same rigor as your part.

Our 4-Step FAI Delivery Process – Built for US/EU Expectations

✅ Step 1: Pre-Production Alignment – Beyond the Drawing

Before molding even begins, our quality engineers cross-check your 2D drawings, 3D CAD models, and GD&T callouts to identify all critical, major, and reference dimensions. We flag ambiguous tolerances (e.g., “±0.1mm on a 0.5mm wall”) and propose alternatives aligned with ISO 20457 or ASME Y14.5.

Case Example ：
A US-based drone startup sent a drawing with 87 dimensions but no priority labels. We categorized them using risk-based dimensioning (critical = snap-fit retention, major = aesthetic surface flatness), which reduced their inspection scope by 40% and accelerated approval.

✅ Step 2: Precision Measurement – CMM + Optical Validation

We use Nikon & Zeiss CMMs (calibrated monthly per ISO 17025) for critical features and Keyence optical comparators for complex profiles like living hinges or micro-textures. Every measurement includes:

• Actual measured value
• Nominal dimension & tolerance
• Deviation from target
• Measurement uncertainty (±0.002mm)

Why it matters：
US clients often require raw numerical data, not just “Pass/Fail.” One European automotive Tier-1 rejected a supplier because their FAI omitted measurement uncertainty—a requirement per VDA 6.3

✅ Step 3: AS9102-Compliant Documentation – Even for Consumer Electronics

While AS9102 originates in aerospace, 85% of our US/EU clients now expect its structure—even for non-aerospace parts .

Our FAI includes:

• Form 1: Part identification & revision control
• Form 2: Material certs (UL, RoHS, FDA), process specs (molding, pad printing, ultrasonic welding)
• Form 3: Full dimensional results with ballooned drawing reference

✅ Step 4: Proactive Response to Common Client Concerns

We anticipate and address the top 3 FAI pain points from US/EU buyers:

Case Example：
A German medtech client questioned why a wall thickness was “exactly” 2.00mm across 5 samples. We provided the full CMM dataset showing values from 1.998–2.003mm, proving natural variation within tolerance—gaining their trust.

Ready to Ship Confidence – Not Just Parts

At our factory, the FAI isn’t a compliance hurdle—it’s a quality handshake with your engineering team. By combining precision metrology, AS9102 discipline, and proactive communication, we turn your FAI from a risk into a competitive advantage.
