Part 1 The Casting Room

The casting room of Taeantech vacuum blue gold bar casting machine is the key part of the machine.  It is responsible for completing the entire process of melting and casting gold in a vacuum environment.


IGBT induction heating: Using the principle of electromagnetic induction, eddy currents are generated inside the metal raw materials to achieve heating.  This method has fast heating speed and high efficiency.  It can melt 2000g of gold, silver and copper in 1-5 minutes, and the metal is not easily oxidized during the heating process.

Fast melting speed:The heating speed is fast, the thermal efficiency is high, and a lot of energy is saved. The heating system is equipped with an advanced automated control system, allowing our machine to cast more than 20kg high-quality gold bars in one hour. The machine can work 24 hours a day, and two people can cast nearly 600kg of gold in one day by taking turns operating it.  The output of this kind of gold ingot is currently far ahead of its peers.  Usually other ordinary ingot casting machines on
the market have slow melting speeds and can only cast less than 10 kilograms of gold in one hour.

Customized mold: The mold is separated from the melting chamber and can be replaced at any time, which is very convenient.   The mold matched with this machine is made of 99.99% graphite, which has the characteristics of high temperature resistance, wear resistance, corrosion resistance, thermal conductivity and low cost.  According to the ingot casting requirements of different customers, molds of various shapes and qualities can be customized.   Taeantech's engineers have rich experience in mold design and guarantee to design molds of various shapes and sizes for free for life for customers of ingot casting machines.

Vacuum protection: 24-hour vacuum protection, no vacuum left, no need for secondary vacuuming.  This is to reduce the contact of metal with oxygen in the air during the smelting and casting process, thereby preventing oxidation and ensuring the quality and appearance of the casting.  In a vacuum environment, the casting room is also filled with inert gas (such as argon) for protection, further reducing the risk of metal oxidation and helping to stabilize the melting and casting process.  The gold nuggets produced in this way have no loss and no bubbles in the finished product.

Chamber seal:Through precise processing and matching, the metal sealing surfaces form a close contact surface to prevent gas leakage. In order to further improve sealing performance, soft sealing materials, such as rubber "O" rings or high-temperature resistant gaskets, are usually embedded between the metal sealing surfaces.

Casting process: First, metal raw materials (such as gold particles) are put into a smelting furnace and heated to a molten state.  Also prepare the mold and vacuum chamber to ensure they are clean and dry.
Second, when the metal is melted, the vacuum chamber is sealed, the vacuum pump is started, and the air in the vacuum chamber is extracted to achieve the required vacuum degree.  This step can effectively prevent the metal from reacting with oxygen and other gases in the air during the casting process, thereby improving the quality and purity of the casting.
Third, molten metal is poured into the mold through a gating system under vacuum.  The pouring system usually includes pouring pipes, gates and other components, which are designed to ensure that metal can flow into the mold evenly and stably.  The metal cools and solidifies into the desired shape in the mold.  Due to the existence of a vacuum environment, metal can avoid defects such as oxidation and inclusion of gases during the solidification process.
Finally, after the metal has completely solidified, the vacuum chamber is opened and the casting is removed.  The gold bars and other castings obtained at this time have smooth surfaces, no defects, high quality and high purity.


Part 2 Mitsubishi PLC control panel

As a high-precision machine in modern gold nugget manufacturing, the control panel of the vacuum automatic ingot casting machine is the core control center of the entire casting process.  Taeantech vacuum blue gold bar casting machine is equipped with Mitsubishi PLC with precise data control.  PLC frees up manpower and enables one person to control multiple units.

Parameter setting: Through the control panel, the operator can conveniently set various process parameters during the casting process.  The precise setting of these parameters is crucial to ensuring casting quality.  The control panel displays the current operating status of the casting machine in real time, helping operators grasp the machine's operating status in a timely manner.  Gas flow management, the control panel is responsible for controlling the flow of inert gas to ensure that sufficient protective gas is provided for smelting and casting during the casting process to prevent metal oxidation.

PID ±1°C temperature control: The casting room can monitor and adjust the melting temperature in real time.  This is essential to ensure the quality of the metal melt and avoid casting defects caused by overheating or cooling.  The Taeantech gold nugget casting machine was designed with environmental requirements in mind and adopted a low-pollution, low-energy-consumption heating method to reduce the impact on the environment.

Safety warning: When a malfunction or abnormality occurs in the gold bar casting machine, the control panel will promptly send out an alarm signal and display a fault code or error message to help the operator quickly locate the cause of the problem.  Human-computer interaction interface, the control panel adopts an intuitive and friendly human-computer interaction interface design, allowing the operator to easily grasp the machine operation method and status information.
