What malfunctions might occur during the mounting process of a metallographic cold mounting machine and how can they be resolved?

The metallographic cold mounting machine may encounter some failures during the mounting process, which need to be resolved in time to ensure the smooth progress of the mounting work.
One of the common failures is incomplete curing of the mounting material, which may be caused by improper material ratio, low ambient temperature, or insufficient curing time; the solution is to strictly follow the instructions to ratio the material, adjust the work environment temperature to an appropriate range, or extend the curing time.
Another failure is the separation of the sample from the mounting material, which may be because the sample surface has oil stains or impurities that were not cleaned thoroughly, preventing the material from adhering well; in this case, the sample needs to be re-cleaned and mounted again.
If a situation arises where the mold is difficult to demold, it may be because the mold was not coated with a release agent or the material adhered too tightly to the mold after curing; an appropriate amount of release agent can be applied to the inner wall of the mold before use, or the mold can be gently tapped to help with demolding.
In addition, if the vacuum embedding machine cannot achieve the expected vacuum effect, it may be due to poor sealing or vacuum pump failure; it is necessary to check whether the seals are intact and repair or replace the vacuum pump if necessary.
