鑄錠模具 — 金銀用小型鑄鐵條模具，紅色手柄，70×35×27mm

The red handle stays cool enough to grip right after pouring, which I didn't expect at this size. Bars come out clean and square at 70 × 35 mm, so they feed straight into my rolling mill without any trimming. Turned a jar of bench scrap into usable stock in one afternoon.

Poured my first silver bar today and it popped right out of the mould with clean edges. The red handle stays cool enough to grip while pouring, which I didn't expect at this size. The 70x35mm bar fits my rolling mill perfectly, so no more trimming.

Finally stopped tossing my bench filings in a jar and melted them into a bar — the 70 × 35 × 27 mm cavity gives a nice compact loaf that fits my rolling mill without any trimming. The red handle stays cool enough to lift the mould right after pouring, which surprised me.
