Walk into a precision workshop in the industrial belt along the Yellow River in Jinan, Shandong, and you will see something unusual: slabs of black granite so large they are moved by overhead cranes, ground and lapped by hand to flatness measured in microns. That workshop is where ZHHIMG — Zhonghui Intelligent Manufacturing (Jinan) Group Co., Ltd. — started, and it is where global customers like GE, SAMSUNG and Apple first learned to trust a Chinese precision supplier with their most demanding components.
This is the story of how a family-rooted granite business became a name that passes international due diligence — and what that means for the next customer evaluating ZHHIMG.

Rooted in Jinan Since the 1980s
ZHHIMG’s founder entered precision manufacturing in the 1980s, first in metal-based precision components, and — after a formative visit to the United States and Japan in 1980 — moved into granite precision components and granite-based metrology instruments. The first formal entity was established in 1998, and as the business expanded, the group was restructured and incorporated as Zhonghui Intelligent Manufacturing (Jinan) Group Co., Ltd. in 2020.
Today the company is headquartered in Shandong’s core industrial zone, near Qingdao Port, with two manufacturing plants in the Huashan and Huadian Industrial Parks covering roughly 200 acres, plus overseas offices in Singapore and Malaysia. That footprint is not just scale — it is what allows a single workpiece of up to 100 tons and 20 meters in length to be produced, inspected and shipped without leaving the group’s control.
Certifications Built for Due Diligence
For a new customer, the first question is rarely about price. It is about whether the supplier can be verified. ZHHIMG answers that question with a certification set that is deliberately international:
- ISO 9001 Quality Management System — certified under CNAS and IAF accreditation
- ISO 14001 Environmental Management System
- ISO 45001 Occupational Health and Safety Management System
- EU CE marking for international compliance
ZHHIMG is one of the few enterprises in China’s ultra-precision manufacturing sector to hold all of these certifications concurrently — a detail that matters when a procurement team needs a supplier whose quality, environmental and safety systems are all independently audited.
Behind the certificates sits a disciplined operating culture: the company runs a 7S management system (Seiri, Seiton, Seiso, Seiketsu, Safety, Saving, Shitsuke) across the entire value chain, from raw-material qualification and dust-controlled production environments to ultra-precise cutting, grinding and lapping, and finally metrological inspection. Critical processes are verified by trained personnel, and state-of-the-art metrology equipment validates flatness, parallelism and surface roughness against specification.
An International Patent and Trademark Position
Certification protects quality; intellectual property protects the customer’s confidence in long-term continuity. Through the Trademark and Patent Office of the China Council for the Promotion of International Trade, ZHHIMG has registered its brand trademarks and core technology patents in key developed markets, including the European Union, the United States and Southeast Asia. To date, Zhonghui Group owns over 100 intellectual property assets — trademarks, patents and software copyrights — covering ultra-precision granite, ceramics, mineral casting, UHPC, precision glass and beyond.

Trusted by Fortune Global 500 and Global Leaders
ZHHIMG is honored to collaborate with many of the world’s leading enterprises, including Fortune Global 500 companies such as GE, SAMSUNG and LG Group. Its partner ecosystem also includes globally recognized names in motion and metrology — HIWIN, THK, HEXAGON METROLOGY, MISUMI and Apple — a network that reflects the trust the precision industry places in ZHHIMG’s components and granite mechanical components.
These relationships are not built on a single product line. ZHHIMG supplies a one-stop portfolio spanning granite precision platforms, granite measuring rulers and air bearings, precision ceramics, precision metal machining, mineral casting, UHPC machine beds, carbon-fiber crossbeams and guide rails, and 3D-printed precision parts — all serving sectors such as Aerospace, Semiconductor, CMM, CNC, Laser machines, Optical, metrology and calibration.
Backed by Universities and Metrology Institutions
Alongside industry, ZHHIMG works with prestigious academic and research institutions, including the National University of Singapore, Nanyang Technological University and Stockholm University. Collaboration with universities and metrology bodies is significant for two reasons: it subjects the company’s components to independent scrutiny, and it keeps ZHHIMG at the leading edge of measurement science — the discipline that defines ultra-precision manufacturing.
The company also offers assembly, inspection and calibration services for precision components in ceramic, metal and granite, closing the loop from raw material to verified, ready-to-install system.
What It Means for a New Customer
When a procurement team runs due diligence on ZHHIMG, the picture is consistent: a company with manufacturing roots going back four decades, an incorporated group structure since 2020, a genuinely international certification set, a cross-border IP position, and a customer list that includes Fortune Global 500 manufacturers and world-class universities. Behind it all is capacity — the ability to process large-volume orders of up to 10,000 sets per month, or a single customized workpiece weighing up to 100 tons.
From a granite workshop in Jinan to the supply chains of GE, Samsung and Apple, ZHHIMG’s growth has one simple engine: the precision business can’t be too demanding.
