- High‑quality metallographic sample preparation forms the foundation of accurate material microstructure analysis, which is critical for aerospace, automotive manufacturing, metallurgical foundry, mechanical processing, quality inspection and university research labs worldwide. Wuxi OCHI Testing Technology Co., Ltd, the brand behind metallographictech.com, is an experienced high‑tech manufacturer focusing on R&D, manufacturing and global supply of metallographic instruments and supporting consumables, with nearly 20‑year industry accumulation, multiple national technical patents and ISO 9001:2015 quality management system certification.
OCHI Testing delivers a complete end‑to‑end metallographic workflow solution covering every core step of specimen processing. Its main product portfolio includes precision metallographic cutting machines, hot & cold mounting machines, manual and automatic grinding & polishing machines, hardness testers, electrolytic polishing & etching analysis instruments, metallurgical microscopes and matched metallographic lab consumables. The precision cutting machines avoid thermal‑induced microstructure damage during sectioning, protecting material integrity for subsequent observation. Mounting machines support both hot compression mounting and cold embedding to handle diverse sample sizes and temperature‑sensitive specimens. Automatic grinding and polishing units adopt touch‑screen control for stable, repeatable surface finishing results, lowering manual operation errors for high‑volume lab testing tasks. Hardness testers provide precise hardness measurement data for metal components, casting parts and new‑generation advanced materials. Electrolytic polishing‑etching instruments streamline metallographic etching procedures to clearly reveal grain boundaries and micro‑defects, greatly improving lab work efficiency. A full line of original mounting resins, polishing media and auxiliary lab consumables guarantee consistent performance matching OCHI hardware devices.
Tailored for multi‑sector real‑world application scenarios, OCHI metallographic equipment serves material evaluation for aerospace turbine blades, additive‑manufacturing composites, automotive welded assemblies and surface‑hardened crankshafts, metallurgy casting defect detection, mechanical component quality verification, as well as material science research inside university and institute laboratories. Beyond standard catalogue products, OCHI provides custom development services for special laboratory requirements, adapting machine parameters and system configurations for unique testing objectives.
Global lab operators gain reliable after‑sales support from OCHI Testing. The brand maintains 7×24‑hour technical assistance, remote troubleshooting, fast spare‑parts delivery and hands‑on operational training, now serving over 500 laboratory clients across the world. Every unit undergoes strict factory testing before shipment to align with international lab equipment quality benchmarks. Whether you are constructing a brand‑new metallography laboratory, upgrading outdated sample‑preparation hardware or sourcing stable‑performance testing consumables, OCHI Testing offers cost‑effective alternatives to high‑priced western‑origin metallographic instruments, balancing precision performance, capital budget and long‑term operational stability for global buyers.
