Description

Technical Field

[0001] The utility model relates to the technical field of detection and analysis, in particular to a chamfer-free plastic cold-mounting mold. Background Art

[0002] Using embedding materials (such as epoxy resins and curing agents) to prepare reflective sheets of powdered or bulk samples into specific specifications for analysis using instruments such as light and electron microscopes is a fundamental method for studying the fundamental properties of materials and is widely used in research fields such as metallurgy and mineralogy. Unlike mineral samples, which are often ground into powders and then cold-mounted using gum, metal samples such as titanium and steel are often mounted directly from appropriately sized blocks due to their unique properties and the need for structural observation. Cold mounting is widely used for sample preparation of more demanding metal materials because it is virtually pore-free after consolidation and can effectively fill cracks. Cold-mounted reflective sheets can produce sharp edges during the grinding and polishing process, which can easily cause scratches of varying depths on the polishing consumables. This is particularly true for bulk metal samples, resulting in difficult-to-remove scratches on the sample observation surface, compromising observation and image quality. In severe cases, these scratches can even result in sample rejection and necessitating re-sampling. To mitigate this issue, manual chamfering of the sample observation surface is often performed to smooth the edges, ensuring the success and reliability of metal sample preparation. Although manual chamfering is not complicated, it is difficult to control the chamfering angle and force, and even unpredictable situations such as improper operation causing samples to splash and injure people. Therefore, a chamfer-free plastic cold mounting mold is needed that is convenient and fast, and can ensure personal safety and the success rate of metal sample preparation. Utility Model Content
