1、 The Function of Metallographic Inlaying Machine


Embedding is a very important step in the preparation process of metallographic specimens, especially for some small and difficult to handle samples.


Metallographic analysis is generally based on microscopic observation of the cross section. Most of the cut samples are irregular in shape, which is inconvenient to hold the grinding sample. Therefore, most of the cut samples need to be inlaid into the shape of standard size.


The embedding of samples with irregular shapes that require edge protection or automatic polishing is an essential process. Scope of application: Suitable for small, irregularly shaped specimens that require edge protection or specimens that require automatic grinding and polishing.


2、 Use of metallographic inlay machine


Hot inlay is to fill the resin particles into the mold, heat them to liquid state, tightly wrap the sample after pressurization, and release the mold after curing. Hot inlay is commonly used for solid materials that are resistant to heat and pressure. Hot embedding is fast and simple, and the sample density is standard, so most metal materials use hot embedding to prepare samples.


3、 Embedding precautions


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


Most of the embedded defects are often hidden, but the impact is severe and difficult to eliminate. Especially the small pores left over due to the density of the sample, which play a storage capacity during the grinding and polishing process. The stored grinding and polishing liquid is released in the next finer grinding and polishing process, which can cause uncontrollable contaminative scratches; In addition, if cracks containing corrosive liquid leak out again after being exposed to strong light during microscopic observation, it will mislead the observation results.
