Widely used for quality testing of fasteners, hardware, and automotive parts, it supports testing standards such as NSS, ASS, and CASS, delivering reliable data for product corrosion resistance evaluation.MORE
Tensile Testing MachineUsed to perform mechanical tests including tension, compression, bending, and shear on metals, non-metals, and components. Precisely measures yield strength, tensile strength, elongation, and more. Ideal for evaluating bolts, nuts, profiles, and other products – ensuring compliance with national standards and customer strength specifications.MORE
Metallurgical MicroscopeUsed to observe internal microstructures of metals – grain size, metallographic structure, inclusions, decarburized layers, weld structure, etc. Microscopic analysis helps evaluate heat treatment quality, forging process rationality, and defects. A vital tool for metal material development and quality control.MORE
Sample Mounting PressUsed to embed small or irregular metal specimens in thermosetting resin for easier handling, grinding, and polishing. Protects specimen edges and internal structures, ensuring complete sample preparation and enhancing the accuracy and consistency of metallographic inspection.MORE
Metallurgical Sample CutterDesigned for high-precision, burn-free cutting of metal materials to produce flat metallographic samples. Features a cooling and lubrication system to prevent heat-induced microstructural changes. Ideal for preparing samples of steel, fasteners, castings, and more.MORE
Metallographic PolisherUsed for grinding and polishing metallographic specimens to achieve a mirror finish for clear microstructural observation under a microscope. Features multi-stage grinding discs and polishing cloths, integrating coarse grinding, fine grinding, and polishing into one process – enhancing metallographic analysis efficiency.MORE
Rockwell Hardness TesterHardness testers (Rockwell, Brinell, Vickers, etc.) rapidly measure metal hardness. Ideal for testing surface hardness and case depth of heat-treated steel and fasteners – evaluating material strength, wear resistance, and heat treatment compliance.MORE
Impact TesterUsed to measure the toughness and impact resistance of metals under impact loads. Measures impact absorbed energy to assess brittle fracture risk under low temperature or dynamic loading. Ideal for quality verification of structural steel, forgings, fasteners, and other critical components.MORE
LatheA fundamental metal cutting machine tool. Rotates the workpiece while feeding the tool to machine external diameters, internal holes, threads, and end faces. Ideal for precision turning of shafts, sleeves, and fastener blanks – offering high accuracy and strong versatility.MORE
