Hasung is a Professional Precious Metals Casting And Melting Machines Manufacturer since 2019.
In the precious metal refining industry, the traditional casting method is inefficient and has become a bottleneck restricting production scale and efficiency. The emergence of fully automatic gold bar casting machines has successfully overcome these bottlenecks through various technological innovations and optimizations, achieving significant improvements in casting efficiency and quality.
1.Automated production process
（1）In the traditional ingot casting process, a large amount of manual operation is often required from raw material preparation, melting, casting to subsequent processing, which is not only inefficient but also prone to human errors. The fully automatic gold bar casting machine has achieved full process automation. It is equipped with an advanced feeding mechanism that can automatically place precious metal raw materials of a set weight into stone ink cartridges or other molds.
（2）The conveying mechanism will accurately transport the mold containing raw materials to the vacuum melting crystallization chamber, where the raw materials are automatically melted, cooled and crystallized to form gold bars. The formed gold bars are transported to the post-processing module through the cutting mechanism for inspection, marking, stamping, weighing, and stacking operations. The entire process does not require manual intervention, reducing labor costs and production delays caused by human factors, greatly improving production efficiency.
2.Efficient heating and cooling system
（1）Rapid heating technology: Fully automatic gold ingot casting machines typically use advanced induction heating technology. Compared to traditional flame heating or resistance heating methods, induction heating can quickly and uniformly heat precious metal raw materials to the desired melting temperature.
For example, some ingot casting machines are equipped with high-power induction generators, which can heat the raw materials above the melting point in a short period of time, greatly reducing the melting time. Moreover, induction heating is carried out in a vacuum environment, avoiding oxidation caused by contact between metal and air, and improving the purity and quality of gold bars.
（2）Optimized cooling system: Cooling speed is also crucial for ingot efficiency and quality. The cooling method of traditional ingot casting machines often has low efficiency, resulting in long ingot casting cycles. The fully automatic gold ingot casting machine adopts an efficient water cooling or air cooling system, and some also combine a water-cooled vacuum chamber and a water-cooled conveyor track.
These cooling systems can quickly remove heat, allowing the molten metal to cool and crystallize in a short period of time. This not only improves production efficiency but also enhances the internal structure and properties of the gold bars, reducing the occurrence of defects. For example, by precisely controlling the flow rate and temperature of cooling water, the crystallization process of gold bars can be made more uniform, improving product consistency.
3.High precision control system
（1）Temperature control: The control system of the fully automatic gold bar casting machine can accurately control the temperature during heating and cooling processes. By installing temperature sensors at critical locations, real-time temperature changes are monitored and data is fed back to the control system.
The control system automatically adjusts the heating power or cooling speed based on preset temperature parameters to ensure that the entire casting process is carried out within a precise temperature range. This not only helps to improve the quality and stability of ingots, but also avoids production accidents or product scrap caused by temperature fluctuations.
（2）Weight control: In precious metal ingots, extremely high precision is required for the weight of gold bars. The fully automatic ingot casting machine can accurately control the input amount of raw materials and the weight of finished gold bars through advanced weighing and control systems.
During the feeding process, the weighing device will accurately measure the weight of the raw materials to ensure that the weight of each input of raw materials meets the set value. After the casting is completed, the weighing device will re weigh the gold bars. For gold bars whose weight does not meet the standard, the system will automatically process them, such as remelting or adjusting the weight, to ensure that the weight of each gold bar is within the specified error range.
4.Improvement of mold and conveying technology
（1）High quality mold materials and design: The fully automatic gold bar casting machine adopts high-performance mold materials, which have good high temperature resistance, wear resistance, and thermal conductivity. For example, some molds use special graphite or alloy materials that can withstand the erosion of high-temperature molten metal and maintain dimensional accuracy and surface quality during repeated use.
At the same time, the design of the mold has been optimized to have a reasonable demolding slope and surface roughness, which facilitates the smooth demolding of the gold bars after cooling, reducing production interruptions and mold damage caused by difficult demolding.
（2）Efficient conveying device: The conveying mechanism is one of the key components to ensure the continuous and efficient operation of the ingot casting machine. The conveying device of the fully automatic gold bar ingot casting machine adopts advanced chain or belt transmission technology, which has the characteristics of high precision, high speed, and high reliability.
The conveying device can accurately transport the mold between various workstations and maintain stability during the conveying process, avoiding the shaking or collision of the mold and ensuring the forming quality of the gold bars. In addition, some ingot casting machines are equipped with automatic detection and adjustment devices, which can monitor the operation status of the conveying device in real time, detect and solve possible problems in a timely manner, and ensure the continuity of production.
5.Online detection and quality control
The fully automatic gold bar ingot casting machine integrates an online detection system, which can perform real-time detection of the appearance, size, weight, etc. of the gold bars during the production process. For example, through a visual inspection system, it is possible to detect whether there are defects, scratches, or bubbles on the surface of the gold bar; Through a laser measurement system, the dimensional accuracy of gold bars can be accurately measured.
Once non-conforming products are found, the system will automatically remove them and record relevant data for analysis and improvement of the production process. This real-time quality control measure helps to detect problems in production in a timely manner, avoid the production of a large number of unqualified products, and improve production efficiency and product quality.
In summary, the fully automatic gold ingot casting machine has successfully broken through the bottleneck of traditional ingot efficiency through various innovations and optimizations such as automated production processes, efficient heating and cooling systems, high-precision control systems, improvements in mold and conveying technology, and online detection and quality control. It has achieved high efficiency, high quality, and automation in the production of precious metal ingots, providing strong technical support for the development of industries such as gold refining.
