PRODUCTS
1. MoPao4S/4
2. iqiege50S


The automatic metallographic grinding and polishing machine performs precise grinding and polishing of metal samples under program control, eliminating cutting marks and preparing mirror-like specimens. It provides a standardized inspection surface for metallographic microscopic analysis.
Suitable for precise cutting of various materials, especially ideal for cutting high-value brittle synthetic crystals.
3. iqiege650S
4. DY-5


Suitable for precise, deformation-free cutting of materials such as metals, electronic components, ceramics, crystals, hard alloys, rock and mineral samples, concrete, organic materials, and biological materials (e.g. teeth and bones).
It can be used with various grinding and polishing machines to automatically dispense polishing liquid between the grinding disc and the sample holder, achieving the desired polishing effect.
5. ixiang5/5S
6. HBRV-187.5S


Small, difficult-to-handle, or irregularly shaped metallographic and petrographic specimens are embedded to facilitate subsequent grinding and polishing operations. Embedding also enables accurate observation of the material’s microstructure under a metallographic microscope and reliable hardness testing using a hardness tester.
7. Auto-HRSA-150S
8. HRS-150S


Applicable for testing the Rockwell hardness of hard metals and alloys, non-ferrous metals, alloy steels, tool steels, quenched steels, thin sheets, stainless steel, cast iron, powder metallurgy materials, copper and copper alloys, aluminum and aluminum alloys, hard plastics, and other materials.
The Rockwell hardness tester measures material hardness using the indentation method. A diamond or steel ball indenter is pressed into the material under a specific load to create an indentation, and the hardness value (HRA, HRB, HRC, etc.) is calculated based on the depth difference of the indentation. It features simple operation and intuitive results, making it ideal for rapid testing of metals, plastics, and other materials. It is a commonly used device in industrial quality inspection.
9. QHV-1000TPTA
10. Auto-HRSA-150S


Suitable for testing the Vickers or Knoop hardness of small metal components, thin sheets, metal foils, and hardened layers, electroplated coatings, nitrided layers, carburized layers, and cyanided layers of workpieces. It can also be used for non-metallic materials such as jewelry, ceramics, and glass that cannot be tested with large test forces.
Suitable for testing metal structures, including small components, thin sheets, metal foils, wires, thin hardened layers, and electroplated coatings. It is also applicable for testing non-metallic materials such as glass, jewelry, and ceramics, which cannot be measured using the Rockwell method or other hardness testing methods that require relatively large test forces.
11. HR-150A
12. MoPao250DE/250


The Rockwell hardness tester measures material hardness using the indentation method. A diamond or steel ball indenter is pressed into the surface under a specific load to create an indentation, and the hardness value (HRA, HRB, HRC, etc.) is calculated based on the depth difference of the indentation. With easy operation and intuitive results, it is ideal for rapid testing of materials such as metals and plastics, making it a commonly used instrument in industrial quality inspection.
This machine is suitable for the preparation of metallographic specimens, from coarse grinding and fine grinding to rough and final polishing. It is an ideal sample preparation equipment for enterprises, research institutions, and laboratory use in colleges and universities.
13. GTQ-5000B
14. iqiege6100S


Suitable for precision, deformation-free cutting of materials such as metals, electronic components, ceramics, crystals, hard alloys, rock and mineral samples, concrete, organic materials, and biological materials (e.g., teeth and bones).
The metallographic cutting machine is mainly used for precisely cutting representative small samples from larger specimens made of metal, ceramics, composite materials, and other materials.
