Fully Automatic Gold Ingot Casting System
The Fully Automatic Gold Ingot Casting System is a state-of-the-art, fully automated production solution specifically designed for the precious metal processing industry. This advanced system efficiently transforms dry neutral gold granules and other gold materials into high-purity gold ingots that meet international standards, including those set by the Shanghai Gold Exchange (SGE) and the London Bullion Market Association (LBMA).
This innovative system integrates essential production processes such as casting, cooling, demolding, polishing, cleaning and drying, quality inspection, marking, and precise weighing. Utilizing a 6-axis robotic arm, the Fully Automatic Gold Ingot Casting System facilitates a fully automated production line, significantly reducing manual intervention and ensuring consistent operational efficiency.
Widely adopted in key sectors of the precious metal industry, this system is ideal for gold refineries, precious metal recycling enterprises, jewelry manufacturing facilities, and downstream processing operations in mining. As a comprehensive solution provider, the Fully Automatic Gold Ingot Casting System offers an integrated workflow that transforms raw materials into refined gold, adhering to the stringent purity, productivity, and compliance standards demanded by contemporary precious metal processing operations.
Key Process Flow
- Raw material pretreatment: Screen dry neutral gold granules/gold materials to remove impurities;
- Precision weighing: Automatic feeding with weighing error ≤20mg;
- Melting & forming: Heating via IGBT power supply, nitrogen-protected melting, and forming with high-purity graphite molds;
- Cooling & demolding: Efficient cooling + automated demolding by robotic arm;
- Polishing & cleaning: Non-damaging magnetic needle polishing, followed by cleaning, drying, and centralized collection of polishing residues;
- Quality inspection: Visual inspection (appearance) + high-precision weighing (0.001g accuracy);
- Marking & traceability: Clear marking on qualified ingots, with system recording batch data for full-process traceability.
