✅ Internal dims provide a 3.5-inch width and 6.75-inch length for standard pours.
✅ Handles extreme heat up to 5000°F for heavy-duty gold and silver melting.
💡 Why do pros pick graphite molds for melting gold and silver over steel alternatives?
This material offers practical benefits that keep your workflow efficient and reduce scrap waste in metal casting operations.
- High thermal conductivity moves heat faster through the graphite block to maintain uniform pour temperatures constantly.
- Non-reactive composition keeps impurities out of your molten pool when processing sensitive alloys like sterling silver daily.
- Tolerates sudden heat changes without fracturing, which saves money on replacements and boosts productivity at the bench handy for busy workshops.
