A complete metallographic sample preparation process includes four core procedures: cutting, mounting, grinding and polishing, and microscopic observation. Among them, metallographic microscopic observation is the final key process, which directly determines the accuracy of metallographic structure analysis and the compliance of test reports. Even if the early sample preparation is well completed, blurred imaging or missing analysis functions of the microscope will cause deviation of metallographic data and invalid test results. Therefore, the selection of professional national standard metallographic microscopes is the core guarantee for standardized laboratory metallographic testing.

All upright and inverted metallographic microscopes of Chongqing Wanwei Instrument are strictly in accordance with national standards. Developed for the microscopic observation of opaque samples such as metals, minerals and precision materials, the equipment integrates high-definition microscopic imaging, national standard intelligent metallographic grading, accurate geometric measurement and standardized report output. With comprehensive functions and stable performance, it is essential for the standardized construction of metallographic laboratories, widely applicable to full-scenario metallographic testing work including industrial quality inspection, new material research and development, university teaching and scientific research, and third-party testing institutions.

Chongqing Wanwei Instrument provides two national standard models: upright metallographic microscope and inverted metallographic microscope, which accurately adapt to different testing working conditions and usage habits.
The upright metallographic microscope is equipped with a 30° inclined trinocular tube, a large-size movable stage and an adjustable halogen light source, featuring convenient operation and clear and transparent imaging, suitable for standardized microscopic observation of conventional samples.

The inverted metallographic microscope adopts a 45° ergonomic lens tube, matched with a rotatable special-shaped stage and professional Köhler illumination system. With shockproof and stable body and wider observation field of view, it effectively relieves fatigue during long-term observation and is more suitable for high-frequency and long-term batch testing in laboratories.

Both metallographic microscopes are equipped with genuine Wanwei metallographic analysis systems, complying with national standard metallographic testing specifications. They support multiple core functions: national standard intelligent metallographic grading, precise geometric dimension measurement, national standard metallographic gallery comparison and custom fixed-magnification printing. Multi-format compliant test reports in Word, Excel and PDF can be generated with one click, realizing standardized, data-based and intelligent metallographic testing throughout the whole process and meeting the high-standard requirements of research projects, industrial quality inspection and third-party testing.

The equipment is applicable to metallographic structure detection of mechanical manufacturing, auto parts and hardware materials; microscopic scientific research experiments of metal materials and new materials; teaching training and project research in university laboratories; standardized metallographic analysis and compliant report issuance of third-party testing institutions.
Standard metallographic analysis originates from standardized sample preparation and ends with accurate observation. Adhering to national standard quality, high-definition imaging and intelligent analysis functions, Chongqing Wanwei upright and inverted metallographic microscopes fully meet various metallographic microscopic testing requirements, helping laboratories achieve full-process standardized metallographic sample preparation and testing.
