A metallographic microscope is used to observe the microstructure of metals.

The test specimens for observation must undergo grinding, polishing, and chemical etching.

Key observation points include metal phases, defects, and grain boundaries.

Universal Testing Machine (UTM)

It is mainly used to perform various static and mechanical tests on materials, including tensile, compression, and bending tests, in order to understand material properties.

The test specimens must be machined on a lathe in advance according to the required specifications to ensure more accurate test results.

A hardness tester is an instrument that applies physical principles to measure the hardness values of various materials.

During measurement, the relevant testing standards must be followed according to the type of material being tested.

Used to test properties such as the compressive and shear strength of molding sand in both dry and wet conditions, serving as a reference for composition adjustment, mold making, and defect analysis.
