Established in 2008, Hongbo Machinery specialises in precision components for automotive transmission, steering and hydraulic systems, serving the global supply chains of leading Tier-1 suppliers. Five process domains are fully in-house.
The company completed its shareholding reform in 2018 and operates an independent R&D centre for automotive steering and transmission components. It is a National High-Tech Enterprise, a Ningbo 'Specialized, Refined, Distinctive and Innovative' SME, and a four-star enterprise for management innovation in Zhejiang Province.
With precision machining as its core competence, Hongbo builds its product portfolio around automotive steering systems, hydraulic systems and new energy powertrains. From raw material to finished delivery, grinding, turning, gear forming, heat treatment and metrology are all completed within our own system without external subcontracting — giving us complete control over lead time and quality.
Managed under the IATF 16949:2016 system, the company links quality requirements to the manufacturing process through GP12 early containment, a temperature-controlled workshop, full-process data traceability and networked MDC equipment — providing stable and reliable supply to global Tier-1 suppliers.
All products are B2B industrial OEM components supplied into the global programmes of leading Tier-1 suppliers.

Grinding, turning, gear forming, heat treatment and metrology are completed entirely within our own system. 280+ machine tools, with no external subcontracting on critical operations.
Double-disc, profile, centreless and cylindrical grinding deliver tolerances down to 0.002 mm.
Hobbing, shaping and two-way rolling keep gears, splines and special slots fully in-house.
A dedicated screw line with controlled-atmosphere heat treatment delivers consistent microstructure and hardness.
19 inspection machines at 0.001 mm accuracy cover dimensions, form, tooth profile, material and cleanliness.
AutoTrace binds work orders and serial numbers across key operations, with real-time equipment monitoring.
GP12 early containment, a temperature-controlled workshop and PPM targets below 50.
Built on the IATF 16949:2016 system, with GP12 early containment, a temperature-controlled workshop, full-process data traceability and networked MDC equipment.
Tightened inspection and containment before new projects reach volume production, driving defects toward zero escape.
Inspection and assembly take place under controlled temperature and humidity to avoid measurement drift.
Work orders and serial numbers are traceable end to end, with automatic alerts on anomalies.
Continuously recognised and trusted by global companies including Danfoss, ZF/TRW, Kawasaki, Setec and HEMA.
Became a global supplier to ZF / TRW, a qualified steering supplier to SGM, and a global supplier to Setec Automotive.
Admitted to the global supply chains of Danfoss Rexroth, Kawasaki and Poclain; selected as a ZF strategic supplier and became a Danfoss strategic partner.
Admitted to the global supply chains of SHW, Shenglong and Cummins, extending into automotive oil pump drive shafts and brake system components.
Our industrial internet platform is built around integrated ERP and MOM systems, connecting downward to equipment and operations and upward to data dashboards and AI agent applications. Business digitalization exceeds 60%, CNC coverage of production equipment exceeds 70%, and the screw line runs at a 90% networking rate.
Work orders and serial numbers traceable end to end, with alerts and records kept on anomalies.
Key operations captured in real time, with data available on the shop floor immediately.
Transparent order status with controllable delivery cadence and capacity loading.
Advancing sustainable operations across environment, safety and governance so that manufacturing capability and social responsibility grow together.
ISO 14001 certified environmental management, rooftop solar power, energy saving and waste recycling — preventing pollution and pursuing cleaner production.
ISO 45001 is being progressively implemented. Full staff safety training, PPE standards and job risk identification; no major safety incident in the past three years.
Conflict minerals control, REACH / RoHS compliance, and business ethics with anti-fraud mechanisms under the IATF 16949 governance framework.
