Metallographic analysis is generally performed by microscopic observation of the cross section. Most of the samples after cutting are irregular in shape, which is inconvenient to clamp and grind, so most of the cut samples need to be inlaid into a standard size.

Hot inlay is to fill the resin particles into the mold, heat it to liquid state, tightly wrap the sample after pressurization, and demold it after curing. Hot inlay is mostly used for heat-resistant and pressure-resistant solid materials. Hot inlay is fast and simple, and the sample is dense and standard, so most metal materials are prepared by hot inlay.

The quality of inlay depends directly on the function of the inlay machine. Some inlay defects are more obvious, such as layering and severe looseness, which directly declares the inlay failure. In some cases, even the sample cannot be recycled and reused.

Most defects in inlays are often hidden, but the impact is serious and difficult to eliminate. In particular, the tiny pores left behind due to the density of the sample act as storage volumes during the grinding and polishing process. The stored grinding and polishing liquid will be released in the next more delicate grinding and polishing process, causing uncontrolled contaminated scratches; in addition, if the gaps storing corrosive liquid overflow again after strong light exposure during microscopic observation, misleading the observation results.

Insufficient hardware and improper parameter settings of the inlay machine may lead to inlay defects. Insufficient hardware such as insufficient heating power and lack of pressurization capacity. Improper parameter settings come from the system's failure to provide a comprehensive system recommendation program.

All microscopic analyses are the accumulation and crystallization of countless details, and the same is true for metallographic analysis. Even the most insignificant errors may create obstacles for subsequent observations. Industry practitioners must be in awe and pursue perfection.
