Shenzhen Hasung Precious Metals Equipment Co., Ltd relying on strong innovation ability and firm R&D perseverance, successfully developed High quality vacuum melting furnace gold silver bullion and ingot casting machine. Technological innovation is the fundamental reason for Shenzhen Hasung Precious Metals Equipment Co., Ltd to achieve sustainable development. Next,Shenzhen Hasung Precious Metals Equipment Co., Ltd will introduce more outstanding talents, invest more research and development funds, and improve market competitiveness.


The design of this equipment system is based on the actual needs of the project and process, using modern high-tech technology.

1. Using German high-frequency heating technology, automatic frequency tracking and multiple protection technologies, it can be melted in a short time, energy saving, and high work efficiency.

2. The closed type/channel type + vacuum/inert gas protection melting chamber can prevent the oxidation of molten raw materials and the mixing of impurities. This equipment is suitable for the casting of high-purity metal materials or elemental metals that are easily oxidized.

3. Adopt closed/channel type + vacuum/inert gas to protect the melting chamber, melting and cooling are performed at the same time, the time is halved, and the production efficiency is increased.

4. Melting in an inert gas environment, the oxidation loss of the carbon mold is almost negligible.

5. With the electromagnetic stirring function under the protection of inert gas, there is no segregation in color.

6. It adopts Mistake Proofing (anti-fool) automatic control system, which is easier to use.

7. Using PID temperature control system, the temperature is more accurate (±1°C).

8. The gold and silver ingot forming equipment/automatic production line is independently developed and manufactured with advanced technical level products for the smelting and casting of gold, silver, copper and other alloys.

9. This equipment uses Mitsubishi PLC program control system, SMC pneumatic and Panasonic servo motor drive and other domestic and foreign brand components.

10. Melting, electromagnetic stirring, and refrigeration in a closed/channel + vacuum/inert gas protection melting chamber, so that the product has the characteristics of no oxidation, low loss, no porosity, no segregation in color, and beautiful appearance.
