【Jewelry Vacuum Casting Machine】

With the continuous development of modern industry, material science, and manufacturing technology are also constantly innovating. In the field of casting, vacuum pressure casting furnace has attracted widespread attention as a key technology. It achieves significant improvements in material properties and casting quality by applying vacuum and pressure during the casting process. This article will delve into the principles, advantages, and application fields of vacuum pressure casting furnaces, aiming to demonstrate the importance and potential of this technology.

1. Principle of Vacuum Pressure Casting Furnace

Vacuum pressure casting furnace is an advanced casting technology, whose core lies in controlling the atmosphere during the casting process to achieve a high vacuum environment and apply additional pressure. This process involves the following key steps

1.1 Vacuum treatment: Before the start of the casting process, the air inside the vacuum casting machine will be extracted to create a high vacuum environment. This can eliminate the presence of gases and impurities, thereby reducing the internal porosity of the casting and improving its density and uniformity

1.2 Pressurization operation: In a vacuum environment, pressure casting can be achieved by applying additional pressure to the molten metal. This pressure can eliminate bubbles inside the casting and promote a more uniform filling of the molten metal into the mold, thereby reducing shrinkage cavities and defects

CDOCAST Jewelry Vacuum Casting Machine is customized and made to melt and cast 1-6 kg of jewelry gold, silver, and other precious metals. Precious metal is melted and cast in an argon-protected atmosphere under a vacuum to protect your precious jewelry from oxidation, It achieves high density, high compactness, almost no air bubbles, and basically achieves non-shrinkage cavity casting. Any precise jewelry and metal artwork can be perfectly done with the CDOCAST Jewelry Casting Machine. We also offer a year-round warranty and worldwide on-site training services.

Feature

1:CDOCAST Jewelry Vacuum Pressurized Casting Machine is designed with the most advanced PID temperature control, Max Temperature can reach up to 1600 degrees Celsius, with a temperature difference only 2 degrees.

2:The strong induction electromagnetic stirring force makes the metal solution more uniform, and the casting quality is higher.

3:The entire melting and casting process is carried out under vacuum, thus minimizing metal oxidation and minimizing metal loss.

4:CDOACAST Jewelry Vacuum Pressurized Casting Machine Equipped with various safety alarms, such as over-current, over-pressure, water shortage and other alarms, when an emergency occurs, the machine can automatically stop

5:Integrated design of the melting and casting chambers for a more compact structure and a smaller footprint for our Jewelry Casting Machine

6: Jewelry Vacuum Casting Machine’s Pressurized casting design highly improves castings’ density and no porosity compare with the traditional casting

Advantage

Advantages of Jewelry Vacuum Pressure Casting Machine

1:Improving the quality of castings: The vacuum pressure casting machine reduces the presence of gases and impurities, making the internal structure of castings dense and reducing the generation of defects such as pores and shrinkage. This helps to improve the mechanical properties and corrosion resistance of castings, making the final product more reliable.

2:Enhanced alloy properties: In a vacuum environment, the oxidation reaction during the casting process is suppressed, thereby reducing the oxidation loss of the alloy. This can maintain the content of specific elements in the alloy and improve its properties and properties

3:Support for complex structural castings: Vacuum pressure casting furnaces can effectively cast castings with complex structures and rich details, as high vacuum environments and pressure operations can ensure more uniform flow of molten metal in the mold, filling fine voids

4: Energy saving: Compared with traditional casting methods, vacuum pressure casting furnaces have lower energy consumption. Due to faster heating and cooling rates in high vacuum environments, the entire casting cycle is shorter, saving energy and time costs.
