[0002] In the process of metallographic specimen preparation, many specimens are difficult to grind and polish directly, and need to be mounted. The specimens that are usually mounted include: irregularly shaped specimens, wires and plates, small workpieces; surface treatment and infiltration layer, plating, etc. Mounting is to turn the metallographic specimens that are not easy to hold or have irregular shapes into regular specimens that are convenient for sample preparation.

[0003] The current cold mounting process for enameled wire is as follows: a cylindrical cup-shaped rubber container is used, a mold release agent is applied to the inside, the cold mounting material is placed in the container, and after the cold mounting agent solidifies into a semi-solid state, the wire sample is vertically inserted into the cold mounting agent, and after it is completely dried, it is taken out, the bottom surface is ground, and then the mirror polishing is performed for inspection and observation. The existing cold mounting method has at least the following defects: (1) a mold release agent is required; (2) the wire sample is inserted manually, and it is difficult to ensure the vertical state of the wire sample. The subsequent inspection and observation will cause the test to fail due to the non-concentricity between the wire and the insert. Utility Model Content
