To obtain reliable test results of material microstructure, standardized metallographic specimen preparation serves as the foundation. The complete specimen preparation workflow consists of four major stages: sampling, mounting, grinding & polishing, and microscopic observation. The performance of equipment selected for each stage will directly affect the final metallographic observation results. Chongqing Wanwei Instrument provides full-range metallographic specimen preparation equipment to complete metallographic sample preparation in one-stop service.

Chongqing boasts concentrated industries of automobile & motorcycle, mold, heat treatment and precision casting. Many manufacturing enterprises’ quality inspection and material laboratories need to independently carry out metallographic structure testing. A complete metallographic sample preparation system mainly consists of four parts: metallographic cutting machine, metallographic mounting press, metallographic grinding & polishing machine and metallographic microscope. Chongqing Wanwei Instrument can customize complete metallographic equipment solutions for enterprises and provide on-site commissioning and on-site practical operation training services.
