Staying informed about the evolving regulatory landscape is key to successful global sourcing. A significant update is approaching: starting January 2026, certain raw steel materials from China will require an export license. However, it is important to distinguish between raw steel commodities and high-precision, custom-fabricated metal products. In this update, we analyze the new MOFCOM

If you’ve ever sourced “cast iron” parts and later realized the supplier delivered something that machines differently, performs differently, or doesn’t match your expectations, it usually comes down to one thing: the spec wasn’t clear enough. ASTM A48 exists to remove that ambiguity. It’s one of the most common standards used in Western markets for gray

You can get internal shapes, ribs, bosses, and near-net geometry that would otherwise take a lot of CNC time. But “aluminum casting” is a broad label, and the results can vary widely

Casting Shrinkage

Casting shrinkage sounds like a simple idea—metal gets smaller as it cools. But in real production, casting shrinkage is one of the main reasons parts end up with internal voids, surface depressions, leaks in pressure-tested components, or “surprise scrap” after CNC machining. The tricky part is that shrinkage isn’t just one event. It happens across
