Your Personal Quality Assurance Team in China

10 years of mechanical drafting experience behind every project

My Story

We are an independent quality assurance team based in Shanghai, specializing in high-pressure flanges and forgings. Because we are not affiliated with any single factory, we are free to select the most suitable partner for your specific requirements—at no extra cost to you. Whether you need a small batch of special materials or a large container order, we match you with the right manufacturer.

I worked closely with manufacturers across China, understanding their capabilities, quality systems, and most importantly, their limitations. This experience gave me unique insights into what makes a supplier truly reliable.

That's why I transitioned to become an independent quality assurance partner. Unlike traditional suppliers who own factories and must push their own production capacity, I'm free to choose the best manufacturer for each specific project based on material expertise, certification requirements, quantity, and delivery timeline.

Every flange I supply comes with full traceability: EN 10204 3.1 certificates, NDT reports, heat treatment curves, and heat numbers. I help clients avoid mismatches, reduce project delays, and sleep better knowing their quality is protected.
