Why Can the Denture Furnace be Vacuumed?

Denture furnaces are indispensable equipment in the process of denture manufacturing. They sinter denture materials at high temperatures to produce durable finished products. As a professional manufacturer of denture furnaces, many users inquire whether our furnaces can operate under vacuum conditions. The answer is yes.

This article will explain in detail the reasons for vacuum operation in denture furnaces.

Reasons for Employing Vacuum Operations

Prevention of oxidation

Protective gases reduce the oxygen content, preventing oxidation of materials during sintering. Oxidation can affect the performance and quality of materials, so controlling the oxygen content can improve the quality of the finished product.

Reduction of gas impurities

Protective gases reduce oxygen and other impurity gases in the furnace, ensuring a relatively pure atmosphere during sintering. This helps avoid the influence of impurities on material performance.

Stable heat distribution

Proper flow of protective gases helps maintain uniform temperature distribution in the furnace, preventing local overheating or cooling, and ensuring even heating of materials during sintering.

Control of the sintering rate

By adjusting the flow and composition of protective gases, the sintering rate can be controlled, affecting grain growth and structure formation of materials, thereby influencing the final product's performance.

How to determine the need for vacuum operation

Non-oxidizing materials: Some non-oxidizing materials, such as silicon carbide, and tungsten carbide, are prone to oxidation reactions at high temperatures, making vacuum operation necessary in such cases.

If you are looking for a denture furnace with a built-in vacuum pump, consider Brother Furnace's T-Run Porcelain Furnace. It features an imported high-quality oil-free vacuum pump and a multi-layer filter structure vacuum tube, ensuring the stability and longevity of related components. With a 10-inch high-definition touch screen and up to 500 built-in programs, it can meet the needs of most laboratories, schools, hospitals, and more.

In conclusion

Denture furnaces equipped with vacuum capabilities can sinter a variety of materials effectively. For more detailed information, please contact Brother Furnace, and we will respond promptly.
