In the precious metal market, gold beans have become a popular product favored by investors due to their small size, portability, and ease of trading. For gold bean production enterprises, how to efficiently and stably produce large quantities of high-quality gold beans is the key to enhancing market competitiveness. The vacuum ingot casting machine, as an advanced casting equipment, has gradually emerged in the field of gold bean production. So, can the vacuum ingot casting machine efficiently achieve the goal of producing multiple gold beans? Next, we will delve into the analysis from multiple dimensions.

1. Working mechanism and key technologies of vacuum ingot casting machine

（1） Working principle

 The operation of the vacuum ingot casting machine relies on a rigorous and precise process. Firstly, place the gold raw material in the melting chamber of the vacuum ingot casting machine. Quickly evacuate the air in the melting chamber through a vacuum pump, creating a highly vacuum environment. This step aims to minimize the oxidation effect of oxygen on the gold raw materials. Subsequently, inert gas such as argon is filled into the melting chamber to further provide a protective barrier for the gold liquid. Then, using efficient heating methods such as induction heating, the gold raw material is rapidly heated above its melting point in a short period of time, melting into a liquid state.

When the gold liquid reaches the ideal casting temperature and has good fluidity, with the help of a carefully designed casting system, the gold liquid is accurately and quickly injected into multiple pre prepared molds. As the gold liquid cools and solidifies inside the mold, molded gold beans are born one by one.

（2） Core technical features

1.Intelligent control system:

Advanced vacuum casting machines are equipped with highly intelligent control systems, usually based on programmable logic controller (PLC) technology. The operator only needs to input preset parameters on the control interface, click the start button, and the equipment can automatically complete the entire process operation from raw material melting, casting to ingot forming.

This intelligent control not only significantly reduces the requirements for operators’ professional skills and minimizes errors caused by manual intervention, but also ensures high consistency in the production process of each batch of gold beans, laying a solid foundation for efficient and stable production of multiple gold beans.

2.Excellent vacuum and inert gas protection:

Under the dual protection mechanism of vacuum and inert gas, the oxidation phenomenon of gold during melting and casting is effectively suppressed. This not only significantly improves the purity of golden beans to extremely high standards, but also greatly reduces the probability of defects such as pores and shrinkage on the surface of golden beans.

Gold beans have a smoother surface and more stable and reliable quality, meeting the market’s stringent requirements for high-quality precious metal products. High quality products help enhance a company’s brand image and market competitiveness, while reducing rework and losses caused by product quality issues, indirectly improving production efficiency.

3.Accurate temperature and flow control:

Accurately controlling the temperature and casting flow of the gold solution is a key factor in ensuring the quality and production efficiency of the gold beans. The vacuum ingot casting machine is equipped with high-precision temperature sensors and flow control valves, which can monitor and accurately adjust the temperature and casting flow of the molten metal in real time. During the melting process, the temperature control accuracy can reach ± 1 ℃, ensuring that the gold liquid is always within the optimal casting temperature range.

In the casting process, the flow control valve can accurately control the injection amount and flow rate of the gold liquid according to the number and specifications of the molds, ensuring the dimensional accuracy and weight consistency of each gold bean. This precise control capability enables the vacuum ingot casting machine to stably produce products that meet strict quality standards in the production of multiple gold beans.

4.Efficient cooling system: 

In order to accelerate the molding speed of gold beans and improve production efficiency, the vacuum ingot casting machine is equipped with an efficient cooling system. This system usually adopts circulating water cooling or air cooling technology, which can quickly remove the heat of the molten metal in the mold, allowing the molten metal to cool and solidify in a short period of time.

Taking the water cooling system as an example, by optimizing the layout of cooling pipes and water flow rate, the cooling time of golden beans can be shortened to about one-third of traditional processes. Rapid cooling not only improves production efficiency, but also enhances the internal organizational structure of golden beans, further improving product quality.

2.Analysis of the advantages of vacuum ingot casting machine in the production of multiple gold beans

（1） Production efficiency advantage

1.Rapid melting and casting process: 

The advanced heating technology used by the vacuum ingot casting machine, such as high-frequency induction heating, can heat the gold raw material to the melting point in a very short time. Compared with traditional resistance heating methods, the melting time can be shortened by more than 50%. For example, some high-performance vacuum casting machines can melt a furnace of gold raw materials (usually several kilograms to tens of kilograms) in just 3-5 minutes.

In the casting process, the high-speed casting device equipped can evenly inject the gold liquid into multiple molds in just over ten seconds. Assuming a mold contains 50 gold bean forming chambers and is cast using a vacuum ingot casting machine, the time required to complete one casting operation may only be about 15 seconds, greatly increasing the gold bean production per unit time.

2.Outstanding continuous production capacity: 

Many vacuum ingot casting machines have the ability to operate continuously. As long as the continuous supply of raw materials, normal operation of cooling systems, and regular maintenance of equipment are ensured, 24-hour uninterrupted production can be achieved.

This continuous production characteristic has significant advantages in dealing with large-scale gold bean production orders. Taking a medium-sized gold bean production enterprise as an example, if a vacuum ingot casting machine with continuous production capacity is used, the daily production of gold beans can reach thousands or even tens of thousands, which can quickly meet the strong demand of the market.

3.Multi cavity mold design:

In order to further improve the production efficiency of gold beans, some vacuum casting machines adopt innovative multi cavity mold design. Dozens or even hundreds of gold bean molding cavities can be set up in a mold, and multiple gold beans can be obtained simultaneously in one casting. For example, some advanced mold designs can produce 100-200 gold beans in one casting. Compared to traditional single-mode or few cavity designs, this multi-mode cavity design has achieved a geometric multiple increase in production efficiency, greatly improving the production scale and speed of gold beans.

（2） Product quality advantage

 1.High purity and low defect rate: 

Thanks to the dual protection of vacuum and inert gas, the gold beans produced by the vacuum ingot casting machine have extremely high purity, usually reaching 99.99% or even higher. At the same time, due to the effective avoidance of oxidation and impurities, the surface of gold beans almost does not have common defects such as pores, shrinkage pores, sand holes, etc., and the surface smoothness is excellent.

High quality golden beans are not only more attractive in appearance, but can also be sold at higher prices in the market, bringing higher profit margins to enterprises. Moreover, a low defect rate means a lower rate of defective products and rework, further improving production efficiency and economic benefits.

 2.Dimensional accuracy and weight consistency:

The vacuum ingot casting machine ensures the dimensional accuracy and weight consistency of each gold bean during the molding process through precise temperature control, flow control, and advanced mold design.

Whether it is large-scale production or small batch customization, the errors in size parameters such as diameter and thickness of the produced golden beans can be controlled within a very small range, and the weight deviation can also be controlled at the milligram level. This high level of dimensional accuracy and weight consistency is particularly important for financial investment gold beans and high-end gift customized gold beans. It can meet customers’ strict requirements for product specifications and enhance the competitiveness of enterprises in these high-end market areas.

（3） Cost control advantage

1.Significant reduction in raw material loss:

Melting and casting are carried out in a vacuum environment, effectively controlling the oxidation loss of gold raw materials. At the same time, the precise casting system can accurately inject the gold liquid into the mold, reducing the splashing and waste of the gold liquid. According to statistics, using a vacuum casting machine to produce gold beans can reduce raw material loss by 10% -15% compared to traditional casting processes. In the long run, this will save companies considerable raw material procurement costs.

2.Reasonable equipment maintenance and energy consumption costs: 

Although the initial purchase cost of the vacuum ingot casting machine is relatively high, it has complete self diagnosis and fault warning functions, which can timely detect potential problems of the equipment and carry out maintenance, reducing the probability of sudden equipment failures, and reducing downtime and maintenance costs caused by equipment maintenance.

In addition, with the continuous advancement of technology, the design of vacuum ingot casting machines is increasingly focused on energy conservation and consumption reduction. Efficient heating elements, optimized cooling systems, and intelligent energy management systems are adopted, resulting in relatively low energy consumption during operation and further reducing production costs for enterprises.
