The core function of the metallographic preparation inlay machine is to achieve the inlay of the sample through the curing process of thermosetting resin. After the equipment is started, the inlay material is heated to a molten state under the action of the heating system, and pressure is applied at this time to fully fill the gap between the sample and the mold. As the temperature decreases, the resin gradually solidifies to form a hard shell that is tightly combined with the sample. This process requires precise control of three key parameters: temperature, pressure, and time: too high temperature may cause the resin to decompose or the sample to oxidize, insufficient pressure cannot ensure that the resin completely wraps the sample, and improper time control will affect the uniformity and density of the inlay.

In order to meet the preparation needs of different materials, modern inlay machines are usually equipped with molds of various specifications and adjustable process parameters. For example, for metal samples with higher hardness, a resin with slightly lower hardness needs to be selected to avoid damaging the sample during grinding; for samples with complex shapes, bubbles in the inlay material need to be removed through a vacuum system to ensure the filling effect. In addition, the design of the cooling system also directly affects the inlay efficiency - water cooling can significantly shorten the curing time and improve equipment utilization compared to air cooling.

The traditional manual inlay method relies on the experience of the operator, and has problems such as low efficiency and unstable quality. The modern metallographic preparation and inlaying machine realizes the full automation from sample placement to inlay completion through integrated temperature control, pressure sensing and programmed operation. Users only need to set parameters and start the equipment to obtain multiple standardized samples in a short time. For example, the automatic inlaying machine can process two samples at the same time, and the single inlay cycle is shortened to 15-30 minutes, which greatly saves experimental time and labor costs.

The temperature and pressure control system of the inlaying machine is the core of its high-precision processing capability. Taking a certain model of equipment as an example, its temperature adjustment range covers 0-300℃, and the pressure control accuracy can reach 0-2 MPa. With the intelligent algorithm, it can realize the free switching of time mode and intelligent mode. This precise control ensures the bonding strength between the resin and the sample, and the prepared inlay has a smooth surface and clear edges, which provides an ideal basis for subsequent microscopic observation.

The metallographic preparation and inlaying machine can process various types of samples such as metals, ceramics, polymer materials and composite materials. According to the characteristics of different materials, users can choose thermosetting resin or cold-setting resin as the inlay material, and adjust the process parameters to achieve the best preparation effect. For example, for samples that are easily damaged by heat, such as electronic materials, low-temperature fast-curing resins can be used; while for samples that require high-strength support, high-hardness thermosetting resins can be selected.

In the material science laboratory, the metallographic preparation inlay machine is a basic tool for studying metal microstructure, phase change behavior and failure mechanism. For example, by preparing samples under different heat treatment conditions, researchers can observe the changing laws of microscopic characteristics such as grain size and precipitate phase distribution, providing a basis for the design of new materials. In addition, the inlay machine can also be used for failure analysis. By preparing the inlay of the fractured sample, combined with equipment such as scanning electron microscopes, the crack source is located and its extension path is analyzed.

In the fields of aerospace, automobile manufacturing and electronics, metallographic analysis is a key means to evaluate material properties and process stability. For example, the fatigue life assessment of aircraft engine blades requires the preparation of inlay samples to observe the initiation and extension of their microscopic cracks; the hardness test of automotive gears depends on the flatness of the inlay surface to ensure measurement accuracy. The high efficiency and stability of the metallographic preparation and mounting machine make it an indispensable quality control equipment on industrial production lines.

In the teaching of materials science and engineering, the metallographic preparation and mounting machine is an important tool for cultivating students' practical skills. Students can master the whole process of sample preparation by operating the equipment, understand the influence of parameters such as temperature and pressure on the mounting quality, and use a microscope to observe the differences in microstructure under different process conditions. This teaching mode that combines theory with practice helps to improve students' engineering literacy and innovation ability.
