Honest caveat: this batch was almost entirely manufacturer promo content from Chinese roll-forming and bending shops. This pick is the least promotional of the bunch — it actually shows a specific part being formed end-to-end.

The video walks through forming a refrigerator door panel from 1mm galvanized sheet on a press brake. That's a useful case study because thin galvanized stock has its own quirks: the zinc coating can flake at tight inside radii, springback behaves differently than mild steel, and any tooling marks on a visible appliance panel become warranty calls.

What's worth paying attention to as you watch: the bend sequence (the order of bends matters enormously on a four-sided enclosure panel — get it wrong and the part can't clear the upper tool on the final hit), the backgauge positioning between bends, and the punch-and-die geometry chosen for a thin sheet (typically a smaller V-die opening, around 6× material thickness, with a sharp or radiused punch depending on the desired inside radius).

For anyone learning sheet metal work, refrigerator panels are a classic teaching part — they combine box-bending, return flanges, and tight tolerance requirements for door seals. Even as a demo reel, watching a real production sequence beats reading about it.
