Advanced mechanical systems engineered for high-load durability, optimal power transfer, and integration into Hai Phong's manufacturing corridors.
Hai Phong has transformed into Northern Vietnam’s primary maritime trade hub and a massive focal point for automotive assembly, shipbuilding, and heavy manufacturing. Anchored by major economic projects like the DEEP C Industrial Zones and proximity to Lach Huyen deep-sea port, the city serves as a key base for enterprises requiring high-performance mechanical systems.
As factories in Hai Phong scale up operations, securing a consistent supply of drivetrain and gearbox components becomes vital. Sourcing parts that conform to international standards like ISO 9001 and IATF 16949 is critical for local manufacturers to integrate successfully with global supply networks.
Guangzhou Yihe Auto Co., Ltd. fills this gap. We provide regional manufacturers in Hai Phong with advanced CNC machined transmission elements, gears, and structural housings. This direct link supports localized assembly lines and minimizes the lead times commonly associated with intercontinental freight.
Direct shipping corridors link Guangzhou's manufacturing center to Haiphong Port, enabling regional operators to lower logistics costs, control pipeline inventories, and secure custom-engineered components.
Combining high precision with automated workflow scheduling to deliver consistent metallurgical and structural performance.
Multi-axis robotic milling cells sustain continuous dimensional consistency, with tolerances down to ±0.005mm for planetary gear sets and splines.
We utilize quality-verified raw stocks like 20CrMnTi steel, custom SG iron, and engineering polyamides to ensure durability under harsh operating conditions.
In-process inspections, 3D coordinate-measuring machine (CMM) reports, and spectrometer steel validation verify alignment with client specifications.

A visual overview of our production halls, CNC lines, raw material storage, and testing rooms that guarantee consistent component delivery to Hai Phong and other international industrial hubs.
The industrial output of Hai Phong depends heavily on specialized equipment that can withstand high stress, humidity, and temperature variations. Our drivetrain components are engineered to perform in these demanding environments:
We supply IATF 16949-certified gear systems, differential housings, and forged hub assemblies designed for vehicle platforms assembled in the Cat Hai district, supporting local production networks.
Container terminals in Hai Phong require rugged power transmission systems. Our custom parallel shaft gearboxes (F-series) and heavy-duty steel spur gears provide the torque required for container gantry drives and winch assemblies.
With the growing clean-energy manufacturing sector in Nomura-Haiphong and Trang Due industrial zones, we provide forged alloy cassette carriers, precision hub assemblies, and low-friction nylon wheels for assembly lines.
We focus on precise heat-treating and metallurgical preparation for all transmission components:
| Material Choice | Typical Heat Treat | Primary Application |
|---|---|---|
| 20CrMnTi Steel | Carburizing & Quenching | Heavy Duty Spur/Helical Gears |
| Ductile SG Iron | Annealing / Normalizing | Differential Housings, Axles |
| Alloy Aluminum | T6 Precipitation Hardening | Robot Arms, Lightweight Brackets |
| Polyamide POM | Stress Relieving | Silent Automation Gears |

Detailed technical information regarding our manufacturing specifications, materials, quality standards, and logistics workflows for the Hai Phong industrial market.
Our production runs operate under IATF 16949 (for automotive applications) and ISO 9001 certification standards. We trace our steel raw stock back to the original foundry heat numbers, and each batch undergoes chemical composition analysis and mechanical property testing before CNC processing.
Standard production runs typically take 25 to 45 days, depending on geometry complexity. Once ready, transport from our Guangzhou center to the regional ports of Hai Phong takes about 3 to 5 days, minimizing pipeline delays for local assembly schedules.
Yes, we provide full OEM and ODM services. Our engineers work from customer-supplied CAD files (.STP, .IGS, or .DWG) to machine custom gearboxes (like the F Series) or cast parts (such as differential housings) to meet specific torque and space constraints.
For heavy machinery gears, we primarily use 20CrMnTi alloy steel due to its excellent core toughness after carburizing. For structural transmission castings, we use high-grade ductile cast iron (SG Iron), while using anodized forged aluminum and engineering POM for lightweight automation systems.
We use 3D coordinate-measuring machines (CMM), gear profile analyzers, and surface roughness testers. Our tolerances are checked to meet ISO Class 6 or DIN Class 6 gear standards, ensuring reliable mesh and low noise levels.
Yes, we customize planetary carriers, ring gears, and sun gears to fit heavy equipment and packaging automation systems used in Deep C, Trang Due, and Nomura industrial zones.
We offer silver chromium electroplating, manganese phosphating, black oxide treatment, and custom anti-corrosion coatings to protect mechanical assemblies in humid maritime port areas like Lach Huyen.
Yes, we manufacture high-precision rotor shafts, engine cylinder block housings, and drive gears engineered to handle the high input speeds and torque levels of modern electric drivetrains.
