Product Description

Product Feature：

1. Adopt medium frequency heating technology, automatic frequency tracking and multiple protection technology, can melt in a short time, energy saving and environmental protection, high efficiency.

2.The melting chamber and casting chamber adopt integrated molding process, which will not cause the risk of air leakage and water leakage due to long working time.

3.The melting chamber adopts closed + vacuum/inert gas to protect the smelting chamber, which is safe and can prevent the oxidation of molten raw materials and impurities from mixing. This vacuum pressure casting machine is suitable for casting high purity metal materials or easy to oxidize elemental metal.

4.Closed + vacuum smelting chamber is adopted, smelting and vacuum-pumping are carried out at the same time, the time is halved, and the production efficiency is greatly improved.

5.In the vacuum environment, the oxidation loss of carbonaceous crucible is small.

6.smelting process with electromagnetic stirring function, no color difference.

7.Use error-proof automatic control system, easy to operate.

8.Using PID temperature control system, the temperature is more accurate (soil 1 degree).

9. Mini semi-automatic vacuum casting equipment is independently developed and manufactured, with advanced technology level products, specially used for smelting and casting of gold, silver, copper and other alloys.

10. Melting, electromagnetic stirring and cooling in the enclosed + vacuum/inert gas protection melting chamber make the products have the characteristics of no oxidation, low loss, no pores, no segregation, beautiful appearance and so on.

Hasung compact vacuum pressure casting machine with an integrated closed chamber and emergency stop switch, designed for gold and silver jewelry production.

• High-purity gold and brass jewelry casting trees with zero pores and a smooth surface finish, produced by advanced vacuum casting equipment.

FAQ

Q1: What is the maximum capacity and compatible metals for this machine?

This 1KG small vacuum pressure casting machine is specifically designed for precious metals and their alloys. It has a maximum casting capacity of 1KG for gold and silver, and is also highly efficient for processing copper and brass.

Q2: How fast is the melting process, and what heating technology is used?

Powered by advanced medium frequency induction heating technology and automatic frequency tracking, this vacuum casting equipment delivers ultra-fast melting, successfully liquefying metal charges within just 1–2 minutes.

Q3: How does the machine prevent metal oxidation and eliminate porosity or color defects?

It features an enclosed smelting chamber protected by a closed + vacuum/inert gas system. Combined with a unique electromagnetic stirring function, it prevents oxidation, minimizes material loss, eliminates segregation, and ensures cast jewelry trees have no pores and zero color difference.

Q4: Is the temperature control accurate enough for high-purity casting?

Yes. The machine integrates a highly precise PID temperature control system that maintains temperature stability with an incredibly tight accuracy tolerance of only ±1°C, making it safe for high-purity or easily oxidized elemental metals.
