Porosity Control & X-Ray Inspection: Ensuring Internal Integrity in Every Casting

Zero-Defect Commitment. Our IATF 16949 Certified Quality Management System ensures precision and consistency for every automotive and industrial component, and our ISO 14001 certified aluminium die casting operation applies the same discipline to environmental compliance. IATF 16949:2016ISO 9001:2015ISO 14001:2015RoHS & REACH Compliant

Our Systematic Inspection Workflow

1

IQC

Incoming Quality Control: Spectrometer analysis of raw ingots (Aluminum/Magnesium) to verify alloy composition. 2

IPQC

In-Process Quality Control: First-article inspection and hourly dimension checks during casting and CNC cycles. 3

Laboratory Testing

X-Ray porosity detection, salt spray corrosion testing, and mechanical property verification (T6/T4). 4

FQC

Final Quality Control: 100% visual inspection and critical dimension verification using Hexagon CMM. 5

OQC

Outgoing Quality Control: Packaging audit and final documentation review before worldwide shipment.

Advanced Metrology Lab

We invest in world-class inspection technology to validate the high-tolerance automotive CNC machining work we perform. Our lab is temperature-controlled to ensure measurement stability.

Porosity & Inspection FAQ

Can you provide 100% X-ray inspection for our entire order? Yes. While many factories only do batch sampling, we have the capacity to provide 100% X-ray inspection for safety-critical components, ensuring every single part delivered meets your internal quality standards. What is the difference between gas porosity and shrinkage porosity? Gas porosity is caused by trapped air or steam and typically appears as smooth, round holes. Shrinkage porosity occurs as the metal cools and contracts, appearing as jagged, irregular voids. We use different vacuum and cooling strategies to eliminate both. Do you provide X-ray reports with the shipment? Absolutely. Every batch can be accompanied by a detailed X-ray inspection report and a certificate of compliance (CoC), providing full traceability and peace of mind for your engineering team.
