Automatic Gold Bullion Vacuum Casting Machine 12KG 15KG 30KG
Why do You Choose Hasung Vacuum Gold Bar Casting Machine ？
Hasung Vacuum Bullion Casting Machines compares to other companies
1. It’s a Big different. other companies vacuum are controlled by time. They are not real vacuum. They just pump it symbolically. When they stop pumping, it is not a vacuum, easily leak out. Ours pumps to the setting vacuum level and can maintain the vacuum for a long time.
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 well-known brands from Japan, France and Germany.

Tunnel Type Gold Ingot Vacuum Casting System
HS-VF260 is an induction tunnel furnace which, although it involves a very advanced technology, is flexible and easy to use. Available in different models, each Tera Automation HS-VF260 is designed, managed and assembled within our company.
Our tunnel furnace is divided into three chambers, where grains are melted in a controlled atmosphere and are casted into glossy and completely flat gold or silver ingots. The patented technology called Pinch Valves, placed at both ends of the tunnel, ensures a perfect sealing: as a matter of fact, this system with pneumatic valves keeps oxygen outside the tunnel, maintaining an inert atmosphere and drastically reducing gas -usually nitrogen – consumption. Graphite consumables last longer and do not deteriorate due to oxidation.
Like all other induction casting furnaces, this furnace needs to be connected to a duly sized water refrigeration installation

VCT Vacuum Pressure Casting Machine for Jewellery
Pressure over Vacuum Casting Machines
VCT is a family of pressure over vacuum casting machines designed to meet the more severe needs in lost wax casting production of gold, K-gold, copper, bronze, alloys. They are often used in connection to a 3d printer for direct casting to get the first metal parts of complex objects.
This family of machines works with a new, revolutionary double chamber concept. This innovative system gives several advantages compared with the traditional single chamber suction system currently available in the market.
In VCT, melting chamber and flask chamber are completely indipendent: while casting, the machine can control the metal injection into the mold by applying a differential pressure during pouring. This yields to a faster injection compared to the simply gravity pouring with the benefit to cast items at lower temperature. This will result in better surface finishing and reduced shrinkage of the cast parts.The casting cycle takes only few minutes and, while the previous flask is cooling down in protective gas for no oxidation, the next charge can be loaded into the crucible and melted, thus overlapping two cycles for no time waste.
The machine is fully automatic, featuring a PC based monitoring system for process parameters acquisition and production data management, with easy editing of casting programs suitable for many kind of alloy.
This revolutionary machine is the synthesis of the most advanced engineering and years of experience in casting that only Hasung will bring in your factory.

Mini Vacuum Pressure Casting Machine for Platinum Palladium Steel Gold Silver
Hasung Precious Metals SVC/MC Equipment advantages
The SVC/MC series are extremely versatile casting machines suitable for a wide range of applications for metal castings – and a number of options that were considered mutually incompatible up to now. Thus, while the MC series was originally designed as a high-temperature casting machine for casting steel, palladium, platinum etc. (max. 2,100° C), large flasks also make it suitable for economically producing castings in gold, silver, copper, steel, alloy and other materials.
The machine combines a dual-chamber differential pressure system with a tilting mechanism. The casting process is achieved by rotating the entire melting-casting unit by 90°. One benefit of the tilting system is the use of economically priced graphite or ceramic crucibles (without holes and sealing rods). These tend to have a longer service life. Some alloys, such as copper beryllium, quickly cause crucibles with holes and sealing rods to become untight and therefore useless. For this reason, many casters have so far processed such alloys only in open systems. But this means they can’t choose to optimise the process with overpressure or vacuum.
