- High‑quality metallographic analysis relies on reliable sample‑preparation workflows and precise testing instruments, which directly determine the accuracy of material microstructure evaluation. OCHI TESTING, operated by Wuxi OCHI Testing Technology Co., Ltd, is an ISO 9001‑certified high‑tech manufacturer supplying complete metallographic equipment, analytical instruments and matching laboratory consumables for global industrial factories, university research institutes, aerospace facilities and automotive quality‑control departments.
The brand covers the full metallographic workflow chain, starting from precision cutting machines for damage‑free sectioning. OCHI precision cutting machines adopt adjustable rotating speed and effective cooling structures, minimizing thermal deformation and mechanical damage when sectioning metal alloys, composite materials and additive‑manufacturing workpieces. After cutting, mounting machines deliver stable hot‑mounting performance to fix irregular specimens for subsequent grinding and polishing operations. Automatic and manual grinding & polishing machines support multi‑step surface refinement, removing scratches and preparing mirror‑finish specimen surfaces for microscopic observation.
For material performance verification, OCHI provides multiple hardness testers for Vickers, Rockwell and micro‑hardness measurement, suitable for thin coatings, welded joints and surface‑hardened components. Its analysis‑instrument lineup includes electrolytic polishing & etching devices, which realise controlled chemical treatment to reveal grain boundaries and micro‑phases of metal samples. Beyond hardware, OCHI supplies a comprehensive portfolio of metallographic consumables: hot mounting resins, grinding sandpapers, polishing fluids and auxiliary chemical supplies, helping laboratories avoid compatibility risks between third‑party spare parts and main devices.
With nearly 20 years of industry accumulation and multiple independent technical patents, OCHI TESTING serves over 500 clients worldwide across aerospace, automotive manufacturing, metallurgy & foundry, mechanical processing and quality‑inspection sectors. Many aerospace research labs and automotive component manufacturers select OCHI solutions for high‑temperature alloy analysis, welded‑structure inspection and batch incoming‑material quality auditing. Customised equipment and system‑level laboratory solutions are available to match unique specimen‑processing requirements.
Global buyers benefit from 7×24‑hour technical support, remote troubleshooting and steady spare‑parts supply. Every unit undergoes strict factory testing under ISO9001 quality‑management standards, balancing high‑end performance and competitive total‑cost‑of‑ownership compared with well‑known Western metallography brands. Whether you are building a brand‑new material‑testing lab or upgrading existing metallographic sample‑preparation stations, OCHI TESTING delivers integrated hardware, consumables and after‑sales service packages for consistent, repeatable metallographic test results.
