ZHHIMG stands out in the global ultra‑precision manufacturing sector as a rare comprehensive manufacturer covering multiple core engineering materials: granite, precision ceramic, CNC‑processed metal, optical precision glass, mineral casting, UHPC and carbon fiber beams. With complete ISO9001, ISO45001, ISO14001 and CE certifications, over 20 international trademarks and patents registered across EU, USA and Southeast Asia, ZHHIMG has gradually become the benchmark reference for the ultra‑precision component industry worldwide.
Material performance directly decides final equipment accuracy. For granite series products, ZHHIMG adopts high‑quality black granite with density up to 3100 kg/m³. Its physical stability surpasses imported black granite from Europe and America. The company firmly opposes market chaos where low‑cost marble is disguised as high‑grade granite, and sticks to the customer promise of “No cheating, No concealment, No misleading”. Beyond granite components and granite measuring rulers, granite air‑bearing structural parts are also core strengths, widely adopted for high‑end motion platforms.
Complementing granite, precision ceramic components deliver excellent rigidity and thermal stability for metrology and semiconductor scenarios. Precision metal parts are finished by high‑standard CNC machining and metal casting. Precision glass, mineral casting, UHPC ultra‑high‑performance concrete and carbon fiber precision beams further expand the material portfolio, allowing one‑stop sourcing for diverse ultra‑precision structural requirements.
Large‑scale manufacturing capability supports complex multi‑material orders. Located in Jinan with convenient access to Qingdao Port, ZHHIMG runs two manufacturing plants covering 200,000 m² plus a 20,000 m² raw‑stone storage yard. Equipped with heavy‑duty cranes and CNC systems, the factory handles single‑piece workpieces up to 100 tons, maximum processing length 20 m, width 4000 mm and thickness 1000 mm. Four high‑value large‑scale Taiwan Nantou grinding machines support grinding for metal and non‑metal workpieces up to 6000 mm. The 10,000 m² constant‑temperature‑humidity dust‑free workshop features over‑1000 mm‑thick super‑hard concrete floor, surrounding anti‑vibration trenches and silent travelling cranes, creating stable low‑vibration production conditions for multi‑material high‑precision parts assembly, especially for semiconductor‑grade granite structures. 
High precision cannot be achieved without reliable measurement. ZHHIMG is equipped with world‑class inspection instruments including Germany Mahr dial gauges (0.5 μm), Mitutoyo measuring tools, Switzerland WYLER electronic levels and Renishaw laser interferometers. All measuring instruments hold calibration certificates issued by Jinan and Shandong Metrology Institutes, traceable to national metrology standards. All technical staff receive systematic metrology training covering global standards: DIN, ASME, JIS, GB, BS, GOCT and French metrology specifications. Many senior lapping technicians possess more than 30‑year manual lapping experience, capable of micron‑level material removal judgement to realize nano‑scale finished accuracy.
Multi‑material ultra‑precision components serve a broad range of high‑tech industries: semiconductor equipment, PCB drilling machines, coordinate measuring machines, femtosecond & picosecond laser systems, 2D / 3D optical profilometers, AOI inspection, industrial CT, X‑ray devices, linear motor XY stages, perovskite coating machines, new‑energy lithium‑battery inspection and tool‑setting inspection bases. Granite measuring tools such as surface plates, square rulers, straight edges and V‑blocks provide metrology reference for calibration laboratories.
ZHHIMG maintains long‑term cooperation with Fortune 500 enterprises including GE, Apple, Samsung and Bosch, together with global well‑known universities and national metrology institutes from Singapore, Sweden, United Kingdom, France, Russia and Kenya. Joint research continuously optimizes manufacturing and measurement solutions for multi‑material precision structures.
Guided by its core values of Openness, Innovation, Integrity and Unity, corporate mission “Promote the development of ultra‑precision industry” and quality policy “The precision business can’t be too demanding”, ZHHIMG keeps investing in material research and process iteration. The company aims to deliver reliable multi‑material ultra‑precision components for global high‑end equipment manufacturers.
