The metal melting machine is equipped with Germany IGBT induction heating technology, automatic frequency tracking, and multiple protection technologies for efficient melting in a short time while saving energy and protecting the environment. Its closed type + vacuum/inert gas protection melting chamber prevents oxidation of molten raw materials and eliminates impurities, making it ideal for casting high-purity or easily oxidized elemental metals. With Mistake Proofing automatic control system and PID temperature control system, this equipment ensures precise temperature control and ease of use, delivering high-quality results in gold, silver, copper, and other alloy casting.

Using Germany IGBT induction heating technology, automatic frequency tracking and multiple protection technologies, it can be melted in a short time, energy saving and environmental protection, and high work efficiency.
2. The closed type + vacuum/inert gas protection melting chamber can prevent the oxidation of molten raw materials and prevent the mixing of impurities. This equipment is suitable for the casting of high-purity metal materials or easily oxidized elemental metals.
3. Using a closed + vacuum/inert gas protection melting chamber, melting and vacuuming are performed at the same time, the time is halved, and the production efficiency is greatly improved.
4. Melting in an inert gas environment, the oxidation loss of the carbon crucible 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). The HS-GR vacuum system casting equipment is independently developed and manufactured with advanced technology and is dedicated to the melting and casting of gold, silver, copper.
9. This equipment uses Japan SMC pneumatic, IDEC, Shimaden, Germany Omron, Siemens, and other well-known brand components at home and abroad.
10. Melting, electromagnetic stirring, and refrigeration in a closed + vacuum/inert gas protection melting room, so that the product has the characteristics of no oxidation, low loss, no pores, no segregation in color, and beautiful appearance.
