The core advantage of the vacuum cold mounting machine is that it can create tightly bonded specimens. Through the built-in vacuum system, the equipment can create a high-intensity vacuum environment during the mounting process, which effectively extracts the air between the sample and the mounting material, allowing the liquid mounting material to fully fill every tiny gap in the sample without pressure. This process not only eliminates bubbles, but also ensures the tight bonding between the mounting material and the sample, achieving dual optimization of structure and performance.

Tightly bonded specimens first improve their structural stability. In conventional cold mounting operations, since the air between the sample and the mounting material is difficult to completely eliminate, bubbles or gaps often exist inside the mounted sample. These defects weaken the structural strength of the sample and make it easy to loosen or break under external force. The vacuum cold mounting machine ensures the integrity and stability of the mounting structure by eliminating these bubbles and gaps, laying a solid foundation for subsequent processing steps.

In the grinding stage, the tightly bonded mounting structure plays a vital role. Grinding is an important step in the sample preparation process, and its purpose is to remove impurities and uneven parts on the sample surface for more detailed analysis. However, if the mounting structure is not tight enough, the sample is prone to loosening or breaking due to external forces during the grinding process, which will not only affect the uniformity of grinding, but also reduce the accuracy of grinding.

The vacuum cold mounting machine effectively prevents the loosening and breakage of the sample during the grinding process by ensuring the tightness of the mounting structure. The tight mounting structure allows the sample to remain stable during grinding, avoiding deformation or damage caused by external forces. Due to the close combination between the mounting material and the sample, the heat and stress generated during the grinding process can also be better dispersed and absorbed, thereby reducing the risk of cracks or breakage on the sample surface. This feature ensures the uniformity and accuracy of grinding, providing high-quality samples for subsequent analysis.

Polishing is the last step in sample preparation, and its purpose is to further smooth the sample surface and eliminate scratches and uneven parts generated during grinding for more detailed observation and analysis. However, the polishing process is also a link that requires extremely high sample surface quality. If the polishing force is too large or the inlay structure is not tight enough, it is easy to cause sample deformation or damage.

The vacuum cold inlay machine provides solid support for the sample during the polishing process through its tight inlay structure. The close combination between the inlay material and the sample allows the sample to remain stable during polishing, avoiding deformation or damage caused by excessive polishing force. The inlay material can also absorb the heat and stress generated during the polishing process, further protecting the integrity and quality of the sample. This feature ensures the ideal polishing effect, making the sample surface smoother and glossier, providing better conditions for subsequent observation and analysis.

In addition to the core functions mentioned above, the vacuum cold inlay machine also has many other technical advantages. For example, modern vacuum cold inlay machines usually use advanced PLC control systems, which can complete the entire inlay process with one click, including multiple steps of vacuuming, maintaining vacuum, and deflation, greatly improving work efficiency and sample preparation quality. At the same time, its large-volume transparent vacuum chamber design allows the operator to intuitively observe the inlay process, which is convenient for timely adjustment and optimization of process parameters.

The application field of vacuum cold inlay machines is also expanding. From porous specimens, micro specimens to materials with micropores, vacuum cold mounting machines can provide precise and efficient mounting solutions. Especially in high-tech fields such as electronics, semiconductors, aerospace, etc., the requirements for sample preparation are getting higher and higher. Vacuum cold mounting machines have become an indispensable and important equipment in these fields with their excellent performance and broad application prospects.

With the continuous development of materials science and metallographic analysis technology, vacuum cold mounting machines are also constantly innovating and upgrading. For example, some advanced vacuum cold mounting machines have been able to achieve intelligent control and can automatically adjust the mounting parameters according to the characteristics and requirements of the sample, further improving the quality and efficiency of sample preparation. The research and development and application of some new mounting materials have also made vacuum cold mounting machines show broad application prospects in more fields.
