Every heat traceable.
Every batch tested.
Quality is not a slogan at INTAFIX — it is the operating budget. 4.6% of revenue goes into metallurgical testing, inspection labor, and independent audits. Here's exactly how it works.
We test everything.
Every batch. No sampling.
Sampling is how failures escape. Every INTAFIX production lot is 100% conformance-tested against dimensional, mechanical, and coating criteria before it leaves the plant. A single fail retires the entire lot — never repackaged, never mixed.
Six lab tests. Every lot.
Zero exceptions.
Our metallurgical labs in Ohio, Stuttgart, and Ningbo run six mandatory conformance tests on every production batch. Third-party spot audits run monthly.
Tensile & Yield
Each production lot pulled to failure on Instron 300 kN frames. Full stress-strain curves attached to the mill test report. Proof-load tested to 92% of UTS.
Rockwell & Vickers
Core & surface HRC / HV measured on 6 pieces per lot. Decarburization depth inspected microscopically. Case depth verified for case-hardened parts.
Salt Spray
NSS & ASS chambers running 240h to 1,000h test cycles depending on coating class. Photographic evidence archived with every batch report.
Optical Scan
Every piece optically scanned on Keyence LM-X quick-vision systems. Diameter, thread pitch, drive geometry, and length verified to 5 μm accuracy.
Torque-to-Tension
K-factor measured on live joints for coated fasteners. Ensures reliable torque-tension relationship in the field. Critical for structural preload applications.
Chemical Composition
Every heat verified on Spectromaxx Spark OES before release. Full chemical composition (C, Mn, Si, P, S, Cr, Ni, Mo, Cu, B) archived per heat number.
From heat number
to your loading dock.
Every INTAFIX pallet carries a QR-coded lot number that resolves to a full production genealogy — steel supplier, heat, cold-heading press, operator, shift, coating batch, and test results.
Heat Number
Wire rod from certified mills — Baosteel, ArcelorMittal, POSCO. OES verified per heat.
Press & Shift ID
Each part tagged with press number, operator ID, and shift timestamp during cold heading.
Furnace Batch
Heat treatment furnace batch number and time-temperature profile recorded per lot.
Coating Bath
Zinc / Ruspert / Xylan bath number, chemistry, and thickness measurement (XRF) attached.
QR Pallet Tag
Bucket, carton, and pallet labeled with QR code linking to full genealogy in customer portal.
