Case 2: European Gold Bar & Silver Ingot Processing Factory Upgrades Vacuum Ingot Casting Machine

Customer Background

A large precious metal refinery in Poland, main business: producing standard investment gold bars, silver ingots for pawn shops, metal traders and small mints. Their old casting equipment could only produce rough ingots with uneven surface and many impurities, failing EU commodity appearance standards.

Core Production Pain Points

1. Open casting process makes ingot surface full of scratches, bubbles and dark oxidation spots, cannot pass European commodity inspection.
2. Manual pouring leads to inconsistent ingot weight, big error rate, causing customer complaints.
3. Long cooling cycle, low daily ingot output, cannot meet growing wholesale order demand.
4. No dust-proof closed structure, metal dust floats in workshop, wasting raw materials and failing local environmental audit.

SanSongMelt Customized Solution

We supplied our full-automatic vacuum ingot casting machine as core production equipment, with full closed vacuum chamber design. The machine realizes automatic melting, vacuum degassing, one-step ingot forming without manual pouring. We adjusted the mold module according to client’s standard ingot size requirements, and added energy-saving constant temperature module to lower power consumption.

• Sealed vacuum environment eliminates oxidation, mirror smooth ingot surface
• Precise weight control system, weight error controlled within ±0.01g
• Integrated dust recycling structure, reduce metal waste and meet EU environmental rules
• Short automatic cooling cycle, continuous batch production

Actual Production Results After 2 Months

1. All gold & silver ingots reach mirror-flawless standard, fully pass EU commodity appearance inspection, new wholesale orders increased by 65%.
2. Metal weight error complaints completely eliminated, customer reputation greatly improved.
3. Daily ingot production capacity raised by 90%, labor cost reduced as one worker can operate 3 machines at the same time.
4. Workshop metal dust pollution solved, successfully passed local environmental protection annual audit without extra renovation cost.
