1. Using high-frequency 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 imported PID program control system, SMC pneumatic and Panasonic servo motor drive 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.
Hasung Precious Metals Equipment advantages
1. The product has uniform color and no segregation:
The porosity is reduced, and the density is higher and constant, reducing post-processing work and reducing loss.
2. Better material fluidity and mold filling, lower enthusiasm risk:
Vibration improves material flow, and the material structure is more compact. Improve shape filling and reduce the risk of hot cracks
3. The grain size is reduced to 50%:
Solidify with a finer and more uniform structure
4. Better and more stable material properties:
The tensile strength and elasticity are increased by 25%, and the subsequent processing performance is improved.
Why do You Choose Hasung Vaccum Pressured Casting Machine ?
Hasung Vacuum Casting machines compare to other companies
1. It’s a Big different. other companies vacuum are controlled by time.They are not vacuum.They just pump it symbolically.When they stop pumping, it is not a vacuum.Ours pumps to the set vacuum level and can maintain the vacuum.
2. In other words, what they have are the vacuum setting time.For example, adding inert gas after one minute or 30 seconds is automatic.If it does not reach the vacuum, it will be converted to inert gas. It is In fact, the inert gas and the air are fed at the same time. It is not a vacuum at all. the vacuum cannot be maintained for 5 minutes.Hasung can maintain a vacuum for more than twenty hours.
3.We are not the same. We have drawn a vacuum. If you stop the vacuum pump,it can still maintain the vacuum. For a certain period of time,we will reach the set After setting the value,it can automatically switch to the next step and add inert gas

4.Hasung the original parts are from well-known domestic Japan and German brands.
